Then assign row names and get rid of column names using the dimnames() function. For example: OLDMatrix <- matrix(c(22, 25, 10, 24, 27, 13, 23, 27, 15), ncol=3, dimnames = list(NULL, c("X1", "X2", "X3"))) NEWMatrix <- rbind(colSums(OLDMatrix ), colSums(!is.na(OLDMatrix ))) dimnames(NEWMatrix) <- list(c("SUM", "COUNT"), NULL) OLDMatrix X1 X2 X3 [1,] 22 24 23 [2,] 25 27 27 [3,] 10 13 15 NEWMatrix [,1] [,2] [,3] SUM 57 64 65 COUNT 3 3 3 Jean Rantony <[hidden email]> wrote on 07/12/2012 12:22:53 AM: > Hi, > Here i have a matrix like this, > > OLDMatrix <- > X1 X2 X3 > ----- ------ ------ > 22 24 23 > 25 27 27 > 10 13 15 > > the thing is, > im running two function(SUM,COUNT) to get output in another matrix called > NEWMatrix > > NEWMatrix <- c("SUM",colSums(OLDMatrix )) > NEWMatrix <- c("COUNT",colSums(!is.na(OLDMatrix ))) > > Actually i need to get output like this, > > NEWMatrix <- > > SUM 57 64 65 > COUNT 3 3 3 > > Instead of getting out put like above, new row getting replaced by new row > of vales. > and after executing the function i getting the values with header.
