well, that's exactly the point, I didn't do anything fancy or special, 
just save the matrix I gave you before (1024 X 768) either in format txt.



That's strange, because

 image <- matrix(0.1, 1024, 768)
 write.table(image, "~/data.txt", col.names=FALSE, row.names=FALSE)
 file.show("~/data.txt")

works fine for me.
Hence I suspect you did something very different, but since you have 
still not provided any piece of reproducible code, we cannot help.


Uwe Ligges







write.table(image, "~/mydata/blablabla/data.txt", col.names=F, row.names=F)

or csv:

write.csv (image, "~/mydata/blablabla/data.csv")


both cases the output is an empty file. Do you know what can be the 
problem?


Thanks a lot,

If I try the same matrix but initialized at 0, it can save it.

It seems that R manages to save up around 800 X 600 decimal  matrices

whether there is a limit in saving such matrices and  how can I work 
around this problem?

 write.table(image, "temp.txt",col.names=F, row.names=F)

saved without problems to working directory. So I suspect that in your 
case it is a problem in specifying the output file. Couldn't  be the 
output file opened in some other programme?
