...9353 -6616.8677 -6498.7183 I would like to sum each row and output the results to another dataframe (Results). The resluts would be Results[1] <- sum(DF[1]) When I try this i get: Error in FUN(X[[1L]], ...) : only defined on a data frame with all numeric variables I have also tried apply(AFDDsec,1,sum) Error in FUN(newX[, i], ...) : invalid 'type' (character) of argument What am I doing wrong? Eventually I would like to do this with a dataframe that has 44 columns and 5329 rows. Cheers, R -- View this message in context: http://www.nabble.com/sum-each-row-and-output-results-tp18...
