note that load() returns, invisibly, a string with the names of the objects that were loaded. something in the lines of:
myObj <- load(file.path(fnDir, cvListFiles[i])) myFunction(get(myObj)) rm(list=myObj) might be closer to what you want. moreover, if length(myObj) > 1, you might want sth like: lapply(myObj, function(x) myFunction(get(x))) instead... best b On Mon, 10 Dec 2007, Talbot Katz wrote: > > Hi. > > I have a procedure that reads a directory, loops through a set of particular > .RData files, loading each one, and feeding its object(s) into a function, as > follows: > > cvListFiles<-list.files(fnDir); > for(i in grep(paste("^",pfnStub,".*\\.RData$",sep=""),cvListFiles)){ > load(paste(fnDir,cvListFiles[i],sep="/")); > myFunction(rliObject); > rm(rliObject); > }; > > where fnDir is the directory I'm reading, and pfnStub is a string that begins > the name of each of the files I want to load.
