Dear R users, Suppose I have 2 parts of a dataframe, say
ABCD 2143 3245 2154 (the real dataframe is 160 columns with each 120 rows) and I want to multiply every element in [,A:B] with every element in [,C:D]; What is the most elegant way to do this? I´ve been thinking of converting [,A:B] to a matrix, and then multiplying it with the inverse of [,C:D]; would that be correct? The result should look like E;F 8;3 12;10 10;4 Thanks very much for any suggestions Christoph ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
