Hi, Kenneth,
I would like a bit more advice on how to use gsub to remove the spaces at
the beginning or the end for a data frame and still keep the data frame in
the same format. The way I see is something like
gsub(' *$', '' , unlist(dataframe)). But the result is not a data frame
anymore. Thanks.
