vector problems
...ies only to vectors
>
Is it a vector or not? This stuff is driving me nuts. I'm simply trying
to convince R that my grouping vector is actually a vector so that
unique will work. Its just a vector of numbers, so why shouldnt it work?

factanal prediction
I was wondering if there is a way of predicting factor scores of new
data for factor analysis in R (similar to "predict" in S-plus). So far I
have not been able to find it, nor found reference to it.
Thanks,

Can one perform a QDA in R? I do not see it anywhere within the mda
package. Any pointers here would be appreciated.

Unexpected warnings from summary() on mcmc.list objects

Forcing standard notation in Sweave tables
I'm hoping someone with some experience generating tables in Sweave will be able to solve this problem for me. I'm experiencing some inconsistency with the way floating point numbers are displayed -- for some tables, they will be in standard notation, e.g.
11±26
while in others, it uses exponential notation, e.g.
1.1e+01±2.6e+01
I am using code such as the following; note I have

RMySQL on OS X
I noticed in the collection of contributed packages for the OSX release
of R, there is no RMySQL package. Does anyone know if one exists, or
