rkward stores dataframe variable labels as variable attribute metadata. It's possible to get a single label, with rk.get.label\(dataframe\[,x\]\), where x is the variable you want. It would be good to get all the labels from a dataframe, and store them as a vector. 

There might be a simpler way to do this, but this works for me:

rk.get.labels &lt;- function\(dataframe\)
\{
labelsvector &lt;- c\(\)
for \(i in 1:length\(dataframe\)\)
\{
labelsvector &lt;- c\(labelsvector,rk.get.label\(dataframe\[,i\]\)\)
\}
return\(labelsvector\)
\}-- Labels: Plugins --

Thanks for the suggestion. I guess it's reasonable to add something like that. However, we really need to start documenting those functions, before we add too much. Let's see what we can do for the next release.

Here's a one-line version of your function:
rk.get.labels &lt;- function \(df\) sapply \(df, rk.get.label\)
