Dear R-helpers,
I have a dataframe that should not contain any negative values, but
it does.
I wish to print the rows from my dataframe that contain a negative
value in
any column. I've tried this:
dataframe[dataframe<0,]
but it just returns a row of NAs.
I would very much appreciate any help with this you could provide.
Thanks, Mark
