Thank you, that means, I have to change spss.get to make it accept the reencode argument and pass it to read.spss. At the moment I prefer to step back to R 2.7.2 and to wait for a more general solution, because to me, there seem to be still strange effects of encoding.

In the following example the encoding gets lost by dumping and rereading, even if I use the encoding parameter of source(). But may be, I don't understand what this parameter should do.

Heinz Tchler

us <- c("a", "b", "c", "", "", "")
Encoding(us)
[1] "unknown" "unknown" "unknown" "latin1" "latin1" "latin1" dump('us', 'us_dump.txt')
rm(us)
source('us_dump.txt', encoding='latin1') us
[1] "a" "b" "c" "" "" ""
Encoding(us)
[1] "unknown" "unknown" "unknown" "unknown" "unknown" "unknown" unlink('us_dump.txt')
