Greetings, friends (and others :) ) We generated a bunch of results and saved them in an RData file. We can open, use, all is well, except that the size of the saved file is quite a bit larger than we expected. I suspect there's something floating about in there that one of the packages we are using puts in, such as a spare copy of a data frame that is saved in some subtle way that has escaped my attention.
Consider a list of objects. Are there ways to do these things: 1. ask R how much memory is used by the things inside the list? 2. Does "as.expression(anObject)" print everything in there? Or, is there a better way to convert each thing to text or some other format that you can actually read line by line to see what is in there, to "see" everything? If there's no giant hidden data frame floating about, I figure I'll have to convert symmetric matrices to lower triangles or such to save space. Unless R already is automatically saving a matrix in that way but just showing me the full matrix, which I suppose is possible. If you have other ideas about general ways to make saved objects smaller, I'm open for suggestions. -- Paul E.
