new function suggestion: get_var_labels

[HanjoStudy]

I find a constantly need to extract and work with the labels of a .sav file after I have read in the file using read_sav. The difficulty is extracting and relabeling the label attribute.

Currently I use the following function from this thread:

get_var_labels = function(data) {
  a = do.call(Hmisc::llist, data)
  tempout = vector("list", length(a))

  for (i in 1:length(a)) {
    tempout[[i]] = Hmisc::label(a[[i]])
  }
  b = unlist(tempout)
  structure(c(b), .Names = names(data))
}

It would be handy if this function formed part of the haven package without having to be dependent on Hmisc

If needed, the labelled package (https://cran.r-project.org/package=labelled) provides dedicated functions to manipulate labelled vectors.

Thanks, this is the type of functionality that I was looking for!
