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.
thanks a lot for any help,

Hello:
I am trying to use fCalendar for date arithmetic and the RMySQL package
for accessing a MySQL database. The fCalendar math operations seem to
work fine UNTIL I load the RMySQL package. Here is a demonstration:

Windows binary packages & R-Forge
Hi room,
There seems to be a problem with the Windows building machines of
R-Forge. All our packages with Fortran source code cannot be compiled
for Windows. The error in the log file is
make[3]: gfortran: Command not found
It seems that gfortran is not installed. Is there any plan to fix this
or am I doing something wrong on R-Forge?
thanks in advance for your advises.
regards,
Yohan

Dear R users,
I have problem with the library fCalendar.

Anyone how knows a way to go around this problem?
Here is the code I enter:
myDate = "12.03.2005"
timeDate(myDate, format = "%d.%m.%Y")
And I get following error message:

Yes. That's the version I've been discussing that has non-zero exit status.
That situation is why CRAN retired the prob package. It's possible you
installed that library earlier in development and it's been "carried"
along. It no longer installs, now.
The problems with all of this seem to have started this month according to
the conversations. However, no one has
