Hi I have a source file in Splus that fails in R as I am using the Splus function compare(). compare( ii * 1e9,f ) where ii is a single variable and f is a vector of length 146 R returns with no function error Can anyone inform me how I can do this in R thanks in advance Bob Kelly [[alternative HTML version deleted]]
