preventing inherited variable labels in r

Question

I have a file of 2,000 columns. In order to help keep all these variables defined, I'd like to use labels and work package Hmisc. So far, so good. My problem: I can't stop any derived variable columns from inheriting the labels.

I don't want var2 to inherit the label from var1 in the assignment below. Is there a way to deactivate this basic behavior in R?!

var1 <- 1:3
label(var1) <- "var one"
str(var1)

Classes 'labelled', 'integer'  atomic [1:3] 1 2 3
..- attr(*, "label")= chr "var one"

var2 <- var1+10
str(var2)

Classes 'labelled', 'integer'  atomic [1:3] 11 12 13
..- attr(*, "label")= chr "var one"

var2 should not be labelled "var one"!!!!

Answer 1

Based on your above example, why not just relabel var2 to something else?

library("Hmisc")

var1 <- 1:3
label(var1) <- "var one"
str(var1)

var2 <- var1+10
label(var2) <- "var two"
str(var2)
