Jens, Im not exactly sure what you meant by "principles of calling batch procedures from other software into R" !?! Would you like to know how R import data from ohter software formats? How other sotwares export into R format? Access these codes? Is that it? R has a lot of different functions to import data from different formats, including, Stata, SAS, SPSS, SQL, MySQL, xls, xlsx, ols (this last a think is available only for UNIX), csv, dbf, revman, and others! I never heard that other software could export to R workspace! However, I have a Stat/Transfer (2007) that has an option to export to R workspace format! Im not sure it work properly though!

R, EpiInfo and opensource software
by epidata-list＠lists.umanitoba.ca 29 Sep '10

29 Sep '10

Hello EpiData Friends, Im just writing a few lines to you at the end of my working day to share some toughts that I have recently. In the last four years I invested a lot of effort and time tring to learn R due to my PhD object. Right now I feel confrtable with R, but in the biginning I felt like banging my head in many places to make stuff work. For the same reason I signed some R mail lists around to trade some doubts and solutions. About three weeks ago, a EpiInfo developer posted a message in epidemiologic issues for R users and it seems that he wanted to go for a EPiInfo - R interface. I was curious and found out that the latest version of EpiInfo available at CDC is 2 years old. My guess is that it is too old for a software. Clearly it was not a oficial CDC contact. Wondering why and how this could be done I realize that most likely R cand do every analysis EpiInfo can and much more. The disadvantageous are: R is is not friedly for the uninitiated, and has no default and complete GUI, although there are several GUIs available. A EPI extesion could be developed in R, while there is already four of them, that I know of. But there some sntroger point to consider in developing stuff in R: (1) opensource software is growing (2) R is opensource (3) R is multi OS (4) R language is reasonbly stable; thus something developed today may last for many many years indently of OS updates or Software updates (5) R has a core team that develop the software itself thus contributers may concentrate efforts in the extension codes and not in the software core, and OS integration. (6) There hundreds of maintainers and contributers thus it is a solid development that even has a early congress for users (7) It is possible, and there is many examples, to create a friendly graphical interface for epidemiologic users (8) There is already many functions directed to epidemiologic users such as epidemic curves, tables in stack form etc Thus I would not be surprised if one day EpiData friends also start an integration with R, as already has been done for SAS, SPSS, WinBugs, SQL, MySQL etc etc and more recently it seems that epiinfo too.

Help - Auto Member Id & Checks
by epidata-list＠lists.umanitoba.ca 29 Sep '10

29 Sep '10

Hi All, I am setting up a parent-child project. At the child level, I need to capture sets of data for every member of household. I have a variable at the beginning which captures Number of people in the household. The problem is I want the Household Member Id to be automated, secondly I want to ensure all members data are captured and equals the total number in the household initially specified. Kindly help with statements to use to achieve these two things. Thank you. Bola Adedoyin DCConsult, Lagos, Nigeria

Hi Jamie Could you please explain why you changed the booleans to 0-1 before loading it into manager? Sorry if this is a silly question. I am asking because someone recently gave me an outbreak file where they had used 0 and 1 (created in Excel 0 = no and 1 = yes). The problem was that when I came to analyse it (in this case using Epi Info) it meant that the two by two tables were in the wrong order. Because no was 0 it came out first in the table. I have always used the boolean field in epidata for our outbreak questionnaires and it has worked very well. They come out in the right order in both Epidata Analysis and Epin Info, and also make intuitive sense to the data entry person. thank you Christine Christine Roseveare Analyst Regional Public Health 570 9194 027 495 9671 >>> <epidata-list(a)lists.umanitoba.ca> 13/09/2010 2:34 p.m. >>> I successfully loaded a moderately-sized .rec file (changing all booleans to 0-1 before loading into Manager--it should prompt to do that for us). Entry handled the existing and new data as expected. I would like to have the autojump to next field when all digits are filled. I assume that this is coming. I successfully loaded a fictitious file with just under 500,000 records and 12 fields (41.8 MB .epx from an 8 MB .rec). Given the capacity of removable memory today, size really isn't a problem. I cannot imagine ever having a real file that large. On my old Windows laptop, this file loaded/saved in 20-30 seconds, but GO TO any record in the file was instantaneous.

Dear Suzanna, Many thanks for your help. The survey questions in which participants have entered more that one tick is like a multiple choice question, however, there is only one right answer. In many of the instances, participants have answered the right answer and also a wrong answer? I was wondering, what you would usually do in this instance?

I would propose that anything other than a single number follow the day and month scheme established for the field. So entering 1011 for a <dd/mm/yyyy> field yields 10 November, but 11 October for a <mm/dd/yyyy> field or <yyyy/mm/dd> field. It's a bit of backwards logic, but would be easily explained to anyone doing data entry.

by epidata-list＠lists.umanitoba.ca 16 Sep '10

16 Sep '10

Dear EpiData list. A new version of the programs EpiData Manager and EpiData Entry Client have been release for public testing. The program can be found in a bundled package on the testing page of EpiData website: http://epidata.dk/testing.php Changes with the new version: * On certain OS's and regional settings, the program could create datafiles (*.epx) that could not be read again. This has been fixed such programs should support local settings for decimal-, date- and time separators, while still being able to work cross-platform. * In the Entry Client "autojump on filled field" has been implemented. * Both Entry Client and Manager have a "Copy Version Info" menu item, that will copy the most needed details about program version and possibly open project to the clipboard. This information is very often vital for locating problems within a program and should be sent with when reporting error to us. Kind regards Torsten Bonde Christiansen EpiData Association.

Hi all, I am new to using epidata and I was wondering if some one could be of help to me. I have put my quantitative questionnaire into epidata & have did the rec & chk forms also. I have assigned variables such as 88-for a question/tick box which any participant has missed or left un-ticked, and 99-for a question/tick box which the answer is unknown- ie If the participant ticks for example both a true & false answer. I am wondering for in the multiple choice aspect of my questionairre, some participants have ticked two boxes and I was wondering how do I deal with this during data entry Into epidata? Or do I need to go back & edit my ques & rec to facilitate this, Thanks in advance for the help, Niamh

Sample file in Entry and how to handle date formulations in entry
by epidata-list＠lists.umanitoba.ca 13 Sep '10

13 Sep '10

Notice that when you open the Entry Client, the file sample.epx is automatically loaded if the file is in the same folder as the exe files. The file contains 12 records with examples of local font texts. If you prefer NOT to have this file loaded every time, then just rename or move the sample.epx to another folder. ...................................................................................................................................................... Specification of entry of dates. Please comment on which strategy you find most attractive: A: The date rule depends on (dmy/mdy/ymd) (current implementation) B. The date rule is independent of type of field (dmy/mdy/ymd): C: Combination of A and B A: Enter digits to the field type first part (YMD/DMY/MDY) and fill in current (day month or year) from "today" for the parts not entered. E.g. one number is day in a DMY field, but year (+2000) in a YMD field. Try this strategy in current sample file. B: one digit: always day - automatically add current month + year two digits: always day - automatically add current month + year three digits: the first two are handled as a day, the third as month four digits: the first two are handled as a day, the third+fourth as month five or more up to 8 digits: the first two as a day, the third+fourth as month, 5 and up as year (+ centenary) C1: one digit: always day - automatically add current month + year two digits: always day - automatically add current month + year if more than two follow same principle as A. C2: one digit: always day - automatically add current month + year two digits: always day - automatically add current month + year three digits: the first two are handled as a day, the third as month four digits: the first two are handled as a day, the third+fourth as month if more than four follow same principle as A. The rule should be simple to explain or else wrong data will be entered. Possibly principle C1 is the simplest to explain. Please comment regards Jens Lauritsen EpiData Association
