Problem to import SPSS database in R

[Scheggia86]

Hi, I am using R console for the first time. I was trying to import SPSS file with Foreign but when I looked for variables, I couldn't find any variables.
EX:> library(foreign)

dosya<-file.choose()
data <-read.spss(dosya, to.data.frame=TRUE)
Ci sono stati 11 avvertimenti (utilizza warnings() per visualizzarli)
objc[54557]: Class FIFinderSyncExtensionHost is implemented in both /System/Library/PrivateFrameworks/FinderKit.framework/Versions/A/FinderKit (0x7fff918183d8) and /System/Library/PrivateFrameworks/FileProvider.framework/OverrideBundles/FinderSyncCollaborationFileProviderOverride.bundle/Contents/MacOS/FinderSyncCollaborationFileProviderOverride (0x11a68bf50). One of the two will be used. Which one is undefined.

What does your data look like? Can you provide the output of head(data))?

I assume that MAP is a column in your file.

What if you tried mean(data$MAP)?
