The following function gives me the means for every 6 rows (96 rows gives me 16 mean values) colMeans(matrix(data.trim$X0, nrow=6)) I would like to do this for ALL columns (a total of 1280 mean values). I tried running this function: colMeans(matrix(data.trim, nrow=6)) but this does not work at all and I get the following error message: Error in colMeans(matrix(data.trim, nrow = 6)) : 'x' must be numeric In addition: Warning
