Converting matrices into row vectors and saving as ASCII text
...ions:
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 lab...

Suggestion: Dimension-sensitive attributes
Hi,
I agree with Henrik that his suggestion to have "dimension vector attributes" working like dimnames (see below) would be an extremely useful infrastructure adittion to R.
If this is not considered for R-core, I am happy to try to implement this in a package, as a new class. And possibly do the same thing for data frames. Should you have any comments, ideas or suggestions about it,
