Dear all, I use R in Batch Mode with the following syntax: X:\...\Rcmd BATCH --slave X\...\test.R X:\...\Log.txt It works very fine. Now I want to write a function and customize the input for my R-File, e.g I want to define the start and the end date. Let's assume that test.R includes only a function like this: analysis<-function(start.date,end.date){...} Is it possible to give the arguments of the function via Batch Mode, e.g. start.date=c("2009-10-01") and end.date=c("2009-10-31")? Normally I would do this as following: result<-analysis(c("2009-10-01"),c("2009-10-31")). Going away from the function: It were sufficent, if the R-Script test.R were running and recognizing start.date and end.date in the same manner as I would write the dates in the top of the file. The background: I am searching for a possibility, that my colleagues can use my files without programming skills in R and without the necessity of opening R. The batch mode is a great thing at this point - the actual problem for me is the missing possibility of define some details. Have you any suggestions to solve my problem? Probably there are other possibilities I don't see at the moment. If other people could enter the dates in the example (in which way respectively in which platform is to define) and start the R-File without R-knowledge, in whatever way, this were the optimal solution. Thank you very much in advance, Jens. -- View this message in context: http://n4.nabble.com/R-Batch-Mode-Customized-Input-tp932947p932947.html Sent from the R help mailing list archive at Nabble.com.
