Hi,
I've been reading the Data Import and Export manual (page 25 on Connection
chapter) but somehow I can't manage to get what I want.
I have a 28x28 distance matrix, which I would like to export to a file.
What I did was something like:
zz <- file("ex.data", "w") # open an output file
connection
cat( traffic.manDist, file = zz ) # traffic.manDist is my matrix name
close(zz)
But instead of exporting the matrix, it export each number in the matrix and
separating each number into one line!
Can anyone tell me where I did wrong? Much appreciated!
Cheers,
Kevin

Try it at the console.> Can anyone tell me where I did wrong? Much appreciated!If you want to export a matrix to a text file, read the section on `export to text files', which is way before page 25. -- Brian D.
