I have encountered a problem reading SAS transport files on both a Mac
(OS X) and Linux (RedHat 9), both using R2.0.1.
After loading "foreign", the command:
read.xport("V1622101_050304.xpt")
yields:
Error in lookup.xport(file) : File not in SAS transfer format
In Linux, I can "cat" the file. The first few lines are:
**COMPRESSED** **COMPRESSED** **COMPRESSED** **COMPRESSED**
**COMPRESSED********LIB CONTROL WIN_PRO<BC>[EMAIL PROTECTED]
SAS8.2<BC><AB>D701DATALIB
ACM<BC><9B>VC30<BC><81>CC14537<BC><85>RL507<BC><87>1<BC><87>S 0 0 20
CHAR
In contrast, I can read.xport a different file successfully.
That file (and others that I can import successfully) contains the
following first line:
HEADER RECORD*******LIBRARY HEADER
RECORD!!!!!!!000000000000000000000000000000 SAS SAS SASLIB
6.12 WIN_NT
21OCT02:13:30:0721OCT02:13:30:07
I know little about SAS but I wonder whether the problem relates to the
export characteristics of different versions of SAS. If so, it appears
that read.xport may not work with newer versions of SAS. If so, is
there a new function to read SAS transport files?
Thanks for any possible help.
