Variable labels and value labels

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

Hi All,

I am using R for social sciences. In this field I am used to use short
variable names like "q1" for question 1, "q2" for question 2 and so on and
label the variables like q1 : "Please tell us your age" or q2 : "Could you
state us your household income?" or something similar indicating which
question is stored in the variable.

Similar I am used to label values like 1: "Less than 18 years", 2 : "18 to
30 years", 3 : "31 to 60 years" and 4 : "61 years and more".

I know that the packages Hmisc and memisc have a functionality for this
but these labeling functions are limited to the packages they were defined
for. Using the question tests as variable names is possible but very
inconvenient.

I there another way for labeling variables and values in R?

Kind regards

Georg Maubach

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?

Kind regards

Georg

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)
