cannot coerce class '"rle"' into a data.frame

why?

rle

Run Length Encoding
  lengths: int [1:1650061] 2 2 8 2 4 5 6 3 26 46 ...
  values : chr [1:1650061] "4bbf9e94cbceb70c BG bg" "4fbbf2c67e0fb867 SK sk" ...

as.data.frame(rle)

Error in as.data.frame.default(vertices.rle) : 
  cannot coerce class '"rle"' into a data.frame

it seems that

rle.df <- data.frame(values=rle$values,length=rle$length)

works and DTRT.
