title: How to correctly `dput` a fitted random forest regression (with caret) to an ASCII file and recreate it later?
body: <p>I want to persist a caret trained random forest model to a file and reload it into another program. I know I can do this by writing/reading a binary file via saveRDS/readRDS, but I'd like to have an ASCII file instead of a binary file. 
  I'd like the file to be minimal but still usable for predictions.
  Something similar to <a href="https://stackoverflow.com/questions/41645120/how-to-correctly-dput-a-fitted-linear-model-by-lm-to-an-ascii-file-and-rec">this</a> but for rf instead of lm.
  Thanks</p>
