I have used R in Windows, but am now trying it on a Mac. I am having problems loading my data as I am not sure how the path names work. Here is what I have tried and am getting errors with: sfs2<-read.delim(???/Users/fj/Documents/Data/Analysis/ student2.txt", header = TRUE, sep = "\t")
If that was cut and paste, it looks as though you used the wrong kind of quotes for the open quote. But the easiest way to get the path right is the same on the Mac as on Windows: use file.choose() rather than typing it explicitly.
That would work, but.... On the Mac the easiest way to get a correct path (at least in Urbanek's GUI version) is to drag and drop. In a console window, set up your read function as: test <- read.table(file="", header = TRUE) and then activate a Finder window with your target file, and click- hold-drag that file so that the cursor is between the quotes and release. A properly constructed reference to the file will appear. Mac- magic ala Urbanek!
