...and also look at sub-models by removing parts of the string etc. What functions should I be looking at here and are there any examples available? Thanks in advance.

...manipulating strings in R is very limited; can anyone recommend some links or available functions which would make the separations and constructions required easy to achieve?

...regsubsets() so that all labelling, fitting, output etc is automatically dealt with. Are there any functions or libraries in R that will allow me to do this without too much grief?

...lti-factor experiments with varying levels per factor and fitting the models within other functions (e.g. regsubsets()) so an automatic solution using what is already available would be far preferable.

I understand this isn't a r specific question. I'm switching departments to work with the analytics team at my company as a "service" side manager to better incorporate the analytics process into product design / production. We're an online gaming company. As I'm going through tools like R, rapidminer, tableau, I was also thinking that I should get some formal training

Hi, I''ve got a newbie question--sorry if this is covered elsewhere, I parsed through the archives for awhile and didn''t see it. I''d like to listen for whenever a file is renamed (e.g. foo.txt -> foo.old) and then magically change it back. This sounds odd, but I''m working with a stubborn application and this will actually make things work nice. So, if I do:

...r.ok = singular.ok, : incompatible dimensions Does this mean I have used manova() wrongly or does it not handle a matrix of weights as required here?
