Hello, I am new to this list and new to the R language. I am currently evaluating the R language to see if it can be helpful. I currently use the SAS language. In SAS, all my data sets are dealt with as files. This is preferable as I tend to work with very large sets of data. I see that R can read and write files of various formats, but can a data set be worked with directly off the disk, not reading it into memory? Thanks for your time. -Jess Balint -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
