I read in spss files using haven's read_spss. Each column then gets attributes
assigned named
label - a long description of the variable
class -" labelled"
labels --- answer labels i.e. 1=Male, 2=Female
example -
> attributes(KPTV[[3]])
$label
[1] "DERIVED: Survey language"
$class
[1] "labelled"
$labels
English Spanish
1 2
However, if I subset the data.frame e.g. MassTV<-KPTV[row selection logic,]
the label attribute disappears
attributes(MassTV[[3]])
$labels
English Spanish
1 2
$class
[1] "labelled"
If I use dplyr to filter the data I simply get an ERROR that the label
attribute is not supported.
> MassTV<-filter(KPTV,KPTV$MNO %in% KPMass$`KPMain$mno`)
Error: column 'MNO' of type numeric has unsupported attributes: label
Any ideas on how I can preserve the label attribute (i.e. the long description
of the variable name?)
Thanks for any help,
Mike
