How to transpose a matrix in R

Question

Which R function should I use to find the transpose of a matrix?

Answer 1

You can use t(); it returns the transpose of a matrix.

Here is an example:

a <- c(10,15,20,12,16,18,17)
b <- c(12,14,23,10,13,19,18)
m <- matrix(c(a,b), nc=2)
m1 <- t(m)

The above code will return the following output (Matrix 'm' and its transpose 'm1'):

> m
     [,1] [,2]
[1,]   10   12
[2,]   15   14
[3,]   20   23
[4,]   12   10
[5,]   16   13
[6,]   18   19
[7,]   17   18
> m1
     [,1] [,2] [,3] [,4] [,5] [,6] [,7]
[1,]   10   15   20   12   16   18   17
[2,]   12   14   23   10   13   19   18
