[R] Enhancement request: lookup.xport() in library foreign
I installed the foreign library yesterday, and have successfully used the read.xport() function to get data from SAS. This is very helpful. SAS "date" and "datetime" variables become numeric variables, which is, of course, what they really are in SAS. Naturally, it is desirable to convert them to date/time objects in R. Looking at the documentation for the SAS transport format, nicely referenced in ?lookup.xport, if appears that SAS format names are present in the transport format file, but not imported into R. If the format name were available, the conversion in R to POSIXct objects would be easier, because the variables that need converting could be identified by their format names. Since I don't know C, I can't take on the task. I would appreciate it very much if the author, or someone else if he's not available, could modify the code to include the format name. Thank you -Don -- the reference -- SAS Technical Support document TS-140: ``The Record Layout of a Data Set in SAS Transport (XPORT) Format'' available as <URL: http://ftp.sas.com/techsup/download/technote/ts140.html>. -- -------------------------------------- Don MacQueen Environmental Protection Department Lawrence Livermore National Laboratory Livermore, CA, USA -------------------------------------- -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
