Try reading the csv file with, say, Notepad. I think you may find that
the problem is that Excel assumes the column is numeric and strips off
the zeros before saving the file. So you need to tell it that the ID
columns are character before saving.
Then you need to read the Help page for read.csv more carefully,
noting, in particular, the "colClasses" argument.
