Dear R-developers,
In read.table() the argument |colClasses = "NULL" can be used to skip
columns and col.names to name the variables. The first time I tried to
skip columns, I naively thought that /first/ the "NULL"-columns are
skipped, /then/ you name only the remaining columns actually specified.
Therefore, I did not provide names (i.e. "NULL") for the (large) number
of columns skipped. When I got the warning message, "Error in
read.table(file = file, header = header, sep = sep, quote = quote, :
more columns than column names", I realized that I have to provide
col.names also for the columns skipped. Now I wonder if it might be an
idea to add a sentence in the help text for colnames (and maybe for
colClasses) that you need to provide colnames = "NULL", for variables
with colClasses = "NULL". Well, just a thought.
I take the opportunity to thank you all for your excellent work with R!
Best regards,
Henrik
