Hi there.
Using read.spss I can read in a file 333 columns, 280 lines, but if I

use

write.table to export it, I only get 256 columns x 280 lines. I can't

find

this feature documented anywhere...

I can't replicate this:

foo<-matrix(rnorm(333*280), ncol=333, nrow=280)
foo<-as.data.frame(foo)
write.table(foo,"foo.txt")
bar<-read.table("foo.txt",header=TRUE)
dim(bar)

[1] 280 333

all.equal(foo,bar)

[1] TRUE

and I can't see why it would be true. Does this example work for you?
 The largest SPSS file I have lying around has only 212 columns, so I
can't test the read.spss aspect of it.
