>for (i in 1:NROW(vector.with.names) You need length instead of nrow (lowercase) which will be NULL for a vector.
>I also want to convert the name from file name to something I can understand For this part of your statement, I think you're after the assign function (included in basic install of R) to go from a string to an object of that name ?assign assign(objectname,values_to_be_assigned_to_object) a<-"doctor2008visit" assign(a,c(7,5,4)) print(doctor2008visit) The opposite of assign() is ?get Depending on what you want to do, this should help you out but if you do use assign() please remember that the object name you work with later in the loop will change each time so you'll need to use get() to copy with that. If reading in a number of files, and processing them, I'll usually just call the variable "input.file" or something like that. The question mark above in my post just means to open up the help page for the function. You can usually use help(functionname) as well. -- View this message in context: http://r.789695.n4.nabble.com/Creating-new-dataset-based-on-variable-name-tp3769285p3769478.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
