I am attaching a new version of import_stata.php that correctly
handles variable labels (the structure of the attribute differed
slightly between SPSS and Stata: first, the attribute is var.labels
rather than variable.labels; second, the var.labels attribute did not
have variable names as column names; so the match has to be done by
column number). Here is the relevant stretch of code for importing
Stata variable labels.
# set variable labels for use in RKWard
labels <- attr (data, "var.labels")
if (!is.null (labels)) {
for (i in 1:length (labels)) {
col <- make.names (attr (data, "names")[i] )
if (!is.null (col)) {
rk.set.label (data[[col]], labels[i])
}
}
}
Try this on
http://wps.aw.com/wps/media/objects/3254/3332253/datasets2e/datasets/Smoking.dta
and you should see the labels for the variables.
Best,
Michael
