R help - Feb 2009 - spss-file problem with foreign 0.8-32

Hi,
after updating to foreign version 0.8-32, I experienced the following error
when I tried to load a SPSS file:

Fehler in inherits(x, "factor") : objekt "cp" nicht gefunden
Zus?tzlich: Warning message:
In read.spss("***l.sav", use.value.labels = TRUE, to.data.frame =
TRUE) :
  ***.sav: File-indicated character representation code (1252) looks like a
Windows codepage

It worked without problems with earlier versions.

Thanks for any clues,
best,
Harry

Yes, something in the logic appears to have gotten garbled.

It's in this part of read,spss:

    if (is.character(reencode)) {
        cp <- reencode
        reencode <- TRUE
    }
    else if (codepage <= 500 || codepage >= 2000) {
        attr(rval, "codepage") <- NULL
        reencode <- FALSE
    }
    else if (m <- match(cp, knownCP, 0L))
        cp <- names(knownCP)[m]

if you get to the 2nd "else if" then cp is unset. Possible the
attempted
match should be of codepage? But it still looks wrong: Why restrict to
codepages between 500 and 2000 when knownCP contains several values
above 10000???

A workaround is to set reencode="ascii" (or whatever is relevant).

It is a issue specific to 0.8-32 and some files (most likely those 
with some (not all) Windows codepages declared).

We are trying to collect together some examples, and will update 
foreign accordingly later in the week.
