[R] macro variable in R?

[karena]

I need to create 10 matrices. say matrix 1-10.

matrix_1 is 1 by 1
matrix_2 is 2 by 2
matrix_3 is 3 by 3
   .
   .
   .
matrix_10 is 10 by 10

I am just wondering if there are some functions in R that are similar to the
macro variables in SAS. so I can create these 10 matrices by doing:
for (i in 1: 10) {
matrix_$i <- matrix(nrow=i, ncol=i)
}

rather thank creating these matrices one by one manually.

Anyone have any suggestions?

thanks,

karena
