Summary: Simple function to get labels from a dataframe.

Initial Comment:
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 <- function(dataframe)
  {
  labelsvector <- c()
  for (i in 1:length(dataframe))
    {
    labelsvector <- c(labelsvector,rk.get.label(dataframe[,i]))
    }
  return(labelsvector)
  }
