Posting under new subject. I?ve a question on saving a earth object to disk. Say m is the model then print(object.size(m), units=?Mb?) 163.8 Mb and save it off save(m, ?tmp.rda?) and ?tmp.rda? is roughly 171Mb file. I would like this to be much smaller. So I try m$bx<-NULL then print(object.size(m), units=?Mb?) 14.9 Mb Great! however when I save it off save(m, ?tmp.rda?) and ?tmp.rda? is roughly 171Mb file ? the same size. I do not care about the size of the file per se, I care about loading a smaller object at a future date. -- View this message in context: http://r.789695.n4.nabble.com/object-size-versus-saved-size-tp4373478p4373478.html Sent from the R help mailing list archive at Nabble.com.
