Saving matrix in Rdata and updating Rdata file

I have a matrix: 

mat<-matrix(data=1:30,ncol=10,nrow=3)

I would like to save this to Rdata:

save(mat, file="m.Rdata")

Then load it back:

m<-load("m.Rdata")

Then look at its contents: 

m
[1] "mat"

All it displays is the name of the matrix saved but the values are lost.

What am I doing wrong?

Also

Once I have saved the matrix I would like to create a new matrix:

mat2<-matrix(data=30:59,ncol=10,nrow=3)

I would then like to save this mat2 into the same Rdata file, what is the right procedure?

use

write.table(mat, file="m.Rdata")
m<-read.table("m.Rdata")

Just use load("m.Rdata")

And try ls(). You should see your matrix name.
