If you are not sure what files are in the current working directory you can use the dir() command to list the files and the getwd() command to determine the current working directory:

> dir()
[1] "fixedWidth.dat" "simple.csv"     "trees91.csv"    "trees91.wk1"[5] "w1.dat"
> getwd()
[1] "/home/black/write/class/stat/stat383-13F/dat"
