problem with package fSeries
Helo,
please look at the log below: after loading the fSeries library, I can not use the log function. Is this a bug or what am I doing wrong?
Because of this, I'm unable to use the garch library.

I am trying to use fCalendar for date arithmetic and the RMySQL package

work fine UNTIL I load the RMySQL package. Here is a demonstration:

read.spss {foreign} doesn't work over network?
I'm unable to open an SPSS file over my network. If I copy it to my
local C:/ drive I can read it. I saved the command (in a "crib sheet"
text file) in order to avoid all the typing, so I'm pretty sure I've
done it before. I verified that the file I'm trying to read is OK.

140 packages in R Commander!!
Dear List
I just downloaded and installed R 2.12.0 and then installed R Commander .
First it got RCmdr and Car, and then suggested for other packages for
utilizing the full functionality- I clicked yes!
I got 140 packages installed!!! Cran Mirror was UCLA...
Here is the list.
Is this intentional- I can see some packages like snow and multicore which
are desirable but quite optional.(see list

Date arithmetic coerces POSIXlt to POSIXct?
Hi. This feels like a bug to me, or at least an undocumented feature,
but I thought I'd see what people here thought of it. Consider a POSIXlt
object like this one:
> a <- as.POSIXlt ("2011-01-23 12:45:45")
> class (a)
[1] "POSIXlt" "POSIXt"
Fine. Now, if I do some arithmetic on that object, the result is
converted to POSIXct.

Comparing two matrices [Broadcast]
It might be a bit faster to do matrix indexing:
R> tbm <- as.matrix(tb) # turn it into a character matrix
R> tmat[cbind(match(tbm[,2], rownames(tmat)), match(tbm[,1],
colnames(tmat)))] <- 1
> tmat
