...using data from each row in the dataframe. It appears that this technique is not scalable to large dataframes without making some changes to the way tempfiles are handled. In the background, R generates tempfiles in a directory using a sequential number. In my case, the numbers ranged from Rf1 to Rf32767. The next in line would of course be Rf32768. This number happens to coincide with 2^15-1, which my programmer colleagues tell me is the maximum positive value a software program with 16 bit processing can create. So, R recognizes that it cannot create a new tempfile and stops the loop. According...

Dear List: I am encountering an error that I can't resolve. I'm looping through rows of a dataframe to generate individual tex files using Sweave. At random points along the way, I encounter the following error Error in file() : cannot find unused tempfile name At which point Sweave halts. There isn't a logical pattern that I can identify in terms of why the program stops at
