Re: [R] Variable labels and value labels

[Jim Lemon]

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)

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

I am not sure this is relevant or helpful, but see ?abbreviate, which
one can use to abbreviate long strings as labels (but only for
English-like languages, I believe).

Seems to me that it is work for factors

nnn <- sample(1:4, 20, replace=TRUE)
q1 <-factor(nnn, labels=c("Less than 18 years", "18 to 30 years", "31 to 60 
years","61 years and more"))

You can store such variables in data.frame with names "q1" to "qwhatever" and 
possibly "Subject"

And you can store annotation of questions in another data frame with 2 columns 
e.g. "Question" and "Description"

Basically it is an approach similar to database and in R you can merge those 
two data.frames by ?merge.

It seems to me strange. What prevents you to use functions from Hmisc?

[R] Variable labels and value labels

[G . Maubach]

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
