Well, factor analysis and pca are different things, and only one
is appropriate in a given problem.

My colleague, who has been helping me with wrapping some older C++ code for use in R,

I summarized this to myself as computed subscripts need explicit
rounding in R, but not in S. Here's the sample code which gave
me different results with R than with Splus. I no longer have
Splus available, so I can't check it again.

If I make a scatterplot and several (e.g. 5) points lie on top of each other
at a given x,y location I would like the plot symbol to be the number of
superimposed points (e.g. 5). Could someone please tell me how to do this
in R? Thanks!

Bill -
The behavior of the old-S function printer() was to count overstrikes
in the way you describe. This was a non-graphics output device which
would make a crude scatterplot using ascii characters (spaces and
asterisks, for example) in response to plot() commands.
I've looked for printer
No problem on a couple of systems here, one Solaris and one Mac OS X.
See below.
The conversion of a character string to a POSIXct is taking place in
two steps--character string to POSIXlt, then POSIXlt to POSIXct.
Which step has the problem?

I believe that Oracle provides ODBC drivers for the server
side--provided you have an Oracle administrator who can figure out
how to install them. I couldn't find much documentation.
For another commercial source see www.openlink.com (don't know if
they have client drivers for Linux).

Are there any tutorials or books for learning R? Of course, I have the
manual, but that seems more of a reference than a teaching tool.

thank you very much for your wonderful clear and short fix of my first problem:
seeing your solution as one-liner in the impressive insightful syntax of R is
