Dear Forum, I am absolutely new to R and have been trying to obtain a deeper understanding of data acquisition using various files types. I have been using the following code to import an SPSS file. The import appears to work successfully, however I receive a warning in the console which I am not entirely sure how to correct. Could anyone please provide insight? Any guidance would be greatly appreciated. human4<-read.spss("human4.sav", use.value.labels = TRUE, to.data.frame TRUE, max.value.labels = Inf, trim.factor.names = FALSE, trim_values = TRUE, reencode = NA, use.missings = to.data.frame) Warning message: In read.spss("human4.sav", use.value.labels = TRUE, to.data.frame = TRUE, : human4.sav: Compression bias (0) is not the usual value of 100 Most Respectfully, Joseph -- Joseph B.
