R help - Jul 2014 - writing matrices of different rows in a file

Hi,
What is the best way of writing of matrices of different rows in a file? Should
the matrices with the same number of rows be written first and then, empty
columns for the matrices with a smaller number of rows followed by the matrices
with a larger number of rows? Not a good solution (see below).

Can't they be written with 1 script?

m = rbind(c(1,2),c(2,44))
n = rbind(c(1,3),c(2,4),c(5,8))

write.csv(cbind(m,n),...)
Error in .Method(..., deparse.level = deparse.level) : 
  number of rows of matrices must match (see arg 2)


write.csv(cbind(m,n[1.2,]),...)
 write.csv(cbind(cbind(rep(" ",1), rep(" ",1)),n[3,]),...)

Warning message:
In write.csv(cbind(cbind(rep(" ", 1), rep(" ", 1)), n[3,  :
  attempt to set 'append' ignored


Thanks

First combine them into one matrix, e.g. with missing values, then write...
