Hi all,
Thanks for all the suggestions. I was able to get the

objects in the directory, and then changing the data
frame into matrix by as.matrix(), splitting the matrix
into 4 blocks and finally using

Hi all,
Thanks for all the suggestions. I
I had a similar problem not long ago. My solution was to
look at the definition of write.table and essentially do it
by hand. The key steps are to create a matrix of characters
that includes the dimnames (if desired), and then use
writeLines to put that into a file.

Patrick,
Thanks for the suggestion. do you mean you need to
change each row of the data frame into a text string
using something like paste(data[1,],collapse='\t')
and then output the resulting character vector into a
file using writeLines?
It seems not working with my data mainly because my
Yes, you have the operation precisely right. What happens if
you coerce your data frame to a matrix:
data.mat - as.matrix(data)
and then do the paste and writeLines?
