Let's back up a little bit. What type of file are you trying to read
into R with this statement? Did you make sure it was a SAS XPORT
format? SAS files often come in the native .sas7bdat format, which R
cannot read (it is proprietary).
At this point, try taking a look at your object "a". At the console
you can type:
class(a)
str(a)
and see what the output says. Is it a data frame? A list? or .... ?
Even if the data is read into R properly, write.csv() may not be able
to properly write all classes of data. You might also try:
print(a)
to make sure there is actually data to be written and it is not just
an empty dataset.
> write.csv(a, file="cool.csv")
Assuming "a" is a matrix or data frame or can readily be coerced to
such, this line should be fine.
Just as a note, if it is a .sas7bdat file, Revolution Analytics now
provides software that can read it into R. There is normally a
charge, but it is free for academics, which, judging by your email
address, you are.
