Peter and all others,
Thank you for your help. I was able to get the file loaded in. The data
set I have is unusual in regards to having spaces inbetween variables.
Usually the columns lack spaces inbetween in my other data sets. In SAS I
would give the variable name then the column #. Is there a similar
procedure in R?
