R help - Sep 2015 - Is it possible to run factor analysis on categorical data.

Dear Rexperts,

I tried running factanal on a group and variables ( all categorical datas ) and
I learnt that's not possible , at least by using factanal. Can I use
FactoMineR for MFA ? Does it do the same thing as factor analysis.

Thanks in advance for the help,
Harmeet

No.

Rhetorical question: You appear not to understand what factor analysis
does, so why are you trying to use it?

In any case, these are statistical questions, and therefore largely
off topic here, which is about R programming. I suggest you:

1) Consult a local statistical expert (your advisor?) for statistical help;

2) and/or post on a statistical site, like stats.stackexchange.com for
further advice and, in particular alternatives for what you might do.
Then you can search R's packages (google generally does pretty well at
this, as does R's "sos" package) for an implementation of the
methods
you decide on.

Cheers,
Bert
