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,
Moreno

Hi everybody,
I am struggling to save txt. or csv. large sparse matrices (1024 X

[10,] 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1
with small distributions located at different points of matrix.
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
but for bigger sizes the output is an empty file. Does anyone know
whether there is a limit in saving such matrices and how can I work
around this problem?
Please tell us what you did exactly when you got the empty file:
