R extract labels from a rda data frame

Question

I am looking at some data downloaded from ICPSR and I am specifically using their R data file (.rda). Beneath the column name of each data file, there are some descriptions of the variables (a.k.a labels). An example is attached as well.

I tried various ways to get the label including base::label, Hmisc::label, labelled::var_label, sjlabelled::get_label and etc. But none worked.

So I am asking any ideas on how to extract the labels from this data file?

Thanks very much in advance!

• ava: cold you add a dput of your data?

Answer 1

this could work using purrr

#load library
library(purrr)
#get col n
n <- ncol(yourdata)
#extract labels as vector
labels <- map_chr(1:n, function(x) attr(yourdata[[x]], "label") )

Answer 2

This worked for me (I am working with ICPSR 35206):

attributes(yourdata)$variable.labels -> labels

Make sure that your attribute referring to the labels is actually called "variable.labels".
