[R] Add row into a Matrix witout headers from Function

[arun]

Hello,

The reason you are only getting one row is because each time you are replacing the NEWMatrix with new output.

Try this:
Oldmatrix<-read.table(text="
 X1        X2        X3
 22          24        23
 25          27        27
 10          13        15
 ",sep="",header=TRUE)
NewMatrix1<-rbind( c("SUM",colSums(Oldmatrix )),c("COUNT",colSums(!is.na(Oldmatrix))))
> NewMatrix1
             X1   X2   X3  
[1,] "SUM"   "57" "64" "65"
[2,] "COUNT" "3"  "3"  "3" 
> NewMatrix1<-data.frame(NewMatrix1)

A.K.

Subject: [R] Add row into a Matrix witout headers from Function

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. How can i
insert row 
of vales into NewMatrix without header. ?

Can anyone please help me ?
Thanks & Regards,
-Antony
