PLEASE, DON'T DO THAT!!!!. Or rather you can do it in your
workspace but
don't post it. It's not fair to a person who may not read your code
line by
line before pasting it into their workspace and having it wiped
out. Do you
expect us to completely clear out our workspaces just so we can
answer your
questions? At the very least comment it out so it doesn't blow away
half a
days work for someone who is trying to be helpful.
If clearing out your workspace destroys *any* work, then something is
seriously wrong with your workflow.
Perhaps, true in some respects. I am still chiseling out work using
primitive editing tools. But it still takes several minutes to load
the objects I am working on into memory and then several minutes each
to build new models. The models still reside in memory, since I do not
know any method for automatically saving the output that would not
further increase the time expended. Typically I am working on .Rdta
files that are 400MB on disk and then are around 4GB in RAM. I need to
make a tradeoff between the time I would lose in saving after every
<n> models or tabulation, versus the security of having everything
saved. If you want to recommend methods that would speed those
processes, I'm surely all ears.
