Subject: Re: [R] Reading xpt files into R
Well yesterday I'd downloaded the "foreign" package and tried to open the xpt
file using that:
library(foreign)
read.xport("test.xpt")
I got the following error and warning messages:
> read.xport("test.xpt")
Error in read.xport("test.xpt") :
The specified file does not start with a SAS xport file header!
In addition: Warning message:
In readBin(file, what = character(0), n = 1, size = nchar(xport.file.header, :
null terminator not found: breaking string at 10000 bytes
I can open the xpt using wordpad and there is a header but it seems to be just
text. I really don't know what constitutes an "
SAS xport file header"

That's what he tried, but the bottom line is that just because something is
called foo.xpt there is no guarantee that it actually is a SAS XPORT file.
Firefox plugins use the same extension but it could really be anything - naming
conventions are just that: conventions.
So dig deeper and find out what the file really is (or was supposed to be).
