suppressWarnings() will get rid of them for you.
Note that in R a factor cannot have duplicate levels. Compare the results with
use.value.labels turned on or off, to see which you prefer.
I also get the "unknown type" warnings, but I ignore them as my data seems to
arrive into R intact.
Hope that helps.
cheers,
Steve

Subject: [R] Reading spss files into R - warnings
Hello people,
I have got a question concerning reading spss files into R:
I used the package foreign and the following command:
read.spss("C:/Eigene Dateien/myspssfile.sav",to.data.frame=T)
I have read two different files into R (several times) and always got the
following two warning messages:
first file:
Warnmeldungen:1: In `levels<-`(`*tmp*`, value = if (nl == nL)
as.character(labels) else paste(labels, :
doppelt auftretende Faktorstufen werden nicht mehr zulässig sein2:
In `levels<-`(`*tmp*`, value = if (nl == nL) as.character(labels) else
paste(labels, :
doppelt auftretende Faktorstufen werden nicht mehr zulässig sein3:
In `levels<-`(`*tmp*`, value = if (nl == nL) as.character(labels) else
paste(labels, :
doppelt auftretende Faktorstufen werden nicht mehr zulässig sein4:
In `levels<-`(`*tmp*`, value = if (nl == nL) as.character(labels) else
paste(labels, :
doppelt auftretende Faktorstufen werden nicht mehr zulässig sein5:
In `levels<-`(`*tmp*`, value = if (nl == nL) as.character(labels) else
paste(labels, :
doppelt auftretende Faktorstufen werden nicht mehr zulässig sein
second file:
Warnmeldungen:
1:
Unerkannter Datensatztyp 7, Untertyp 14 in Systemdatei vorgefunden2:
Unerkannter Datensatztyp 7, Untertyp 18 in Systemdatei vorgefunden
I couldn't find out how to get rid of these.
Does anyone know how to do this?
Thank you very much in advance,
Marion
