I had the same error message so I went googling a bit I managed to fix it with the following code.

df<-data.frame(words = unlist(words))

words is a character list.

This just in case somebody else needs the output to be a data frame.

Though this isn t a DIRECT answer to your question  I just encountered a similar problem  and thought I d mentioned it   I had an instance where it was instantiating a new  no doubt very inefficent  record for data frame  a result of recursive searching  and it was giving me the same error   I had this   return    data frame      user id   gift email      sourced from agent id   gift source      method used   method      given to   gift account      recurring subscription id   NULL      notes   notes      stringsAsFactors   FALSE         turns out    it was the   NULL   When I switched to   NA  it worked fine   Just in case anyone else with a similar problem hits THIS post as I did

Your data frame mat is rectangular  n rows   n cols    Therefore  you cannot make a data frame out of the column- and rownames  because each column in a data frame must be the same length   Maybe this suffices your needs   require reshape2  mat id  lt - rownames mat   melt mat
