Hi, How can I import user-defined missings from Spss?
It works for me to import spss datasets via library(foreign) with read.spss or via library Hmisc by (spss.get). But no matter which way I do import the data, user-defined missings from Spss are always lost. (it makes no difference if there are a single value, a range, or any combination of them. They are always ignored). Is there any way in R to find out if any value was user-defined missing in Spss or not? Even to keep the information as an attribute would suit me fine, or to keep them as a string character like "miss" would be even better. To transform them into "NA" as the sysmis data from Spss is transformed automatically, would be an other alternative. Unfortunately I don't know if any of these options are possible. Could you help me out? Many thanks.
