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) )

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.
Thanks

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.
Thanks
Xi
