[R] Converting matrices into row vectors and saving as ASCII text
Hi I have some data with these dimensions: 5 3 100 which correspond to the x, y, and time dimensions, for a variable, p. I need the data in this format: 100 rows (1 row per time unit), and 15 values in each row. I have attempted to reshape my data dim(data) 5 3 100 attr(data,'dim')-c(dim(data)[3],dim(data)[1]*dimdata[2]) So I get data with 100 rows, 15 columns. I need to use this data outside of R, and so have to save it as an ASCII file that retains the row-column structure of the data, but I do not know how to. It would be ideal if I could end up with a text file that also has an additional column that labels which time unit (1-100) the row belongs to, i.e. 1 a1,1 a1,2 ... a1,15 2 a2,1 a2,2 ... a2,15 3 a3,1 a3,2 ... a3,15 4 a4,1 a4,2 ... a4,15 . . . 99 100 Any suggestions would be appreciated.

Re: [R] Converting matrices into row vectors and saving as ASCII text
Thanks for your reply. Is there a way I can save the data to an ascii file without losing the row/column structure? I have tried save(...) and write.table(...) but the output file seems to jumble up the order of the matrix.

?cat ?apply ?t You could follow each row of the transposed matrix with a newline: apply(t(XYbyT), 1, function(x) cat(x, \n, file=output.txt, append=TRUE) ) On Sep 19, 2009, at 8:11 PM, Xi Ang wrote: Thanks for your reply.

If the only reason you want to save it is to later read it back into R later then see ?dump or even ?save On Sat, Sep 19, 2009 at 8:11 PM, Xi Ang slideprojec...@gmail.com wrote: Thanks for your reply.
