Hi Georg, You may find the "add.value.labels" function in the prettyR package useful.

[R] Antwort: Re: Variable labels and value labels
Hi Jim, many thanks for the hint. When looking at the documentation I did not get how I do control which value gets which label. Is it possible to define it?

Hi Georg,
add.value.labels simply creates an attribute named "value.labels" for
the sorted values of the vector passed to it. The value labels passed
become the names of this attribute in the sorted order. The function
is intended to mimic a factor in reverse. While the factor adds
sequential numeric values to the original values, add.value.labels
adds names to the values passed. It was intended to be a mnemonic for
numeric values that perhaps should have been coded as character. If I
wrote this function now, it would probably look like this:
value.labels<-function(x,labels) {
if(missing(labels)) return(attr(x,"value.labels"))
else {
attr(x,"value.labels") <- sort(unique(x))
lenvallab <- length(attr(x,"value.labels"))
if (length(labels) > lenvallab) {
cat("More value labels than values, only the first",
lenvallab, "will be used\n")
labels <- labels[1:lenvallab]
}
names(attr(x, "value.labels"))<-labels
return(x)
}
}
age<-sample(1:5,100,TRUE)
value.labels(age)
age<-value.labels(age,c("0-19","20-39","40-59","60-79","80+"))
age
value.labels(age)
