Good morning! Which is the preferred method to leave a sourced script and returning back to the '>' prompt?
For example I search for certain files to be processed, but nothing should be done if they are not present. Normally I do in my script: f<-dir(pattern="qq") if(length(f) > 0) { ...process file list... } # script end But I don't like those {} encompassing the whole script so I'm searching for something to put in place of the '???' here: f<-dir(pattern="qq") if(length(f) == 0) '???' ...process file list... # script end Using stop("No file found", call.=F) works, but the Error message is ugly in this case. Any suggestion? Thanks for your help! mario -- Ing.
