How to mount a samba partition in Linux?
I have installed Samba 2.2.1.a. From windows it works allright. From Linux I
can browse with smb://server. But I do not have write permissions. When I
open a console and in this console enter the command smbclient
//server/folder I do have write permissions. Someone told me to mount samba
with mount -t smb -o username=***,pasword=*** \\192.168.0.1\folder

*OUTPUT/*INPUT typemaps
Hi
Have been looking again at SWIG output pointer parameters, as:
http://www.swig.org/Doc1.3/Ruby.html#Ruby_nn32
The problem is, whenever I tried to include the SWIG/Ruby ''typemaps.i''
file, it threw loads of errors.
A bit more investigation pinned the problem down to some secondary files
that typemaps.i includes to map ''special'' types like File.
So I tried

par(tmag) question
Dear list,
I'm trying to understand the graphical parameters by a systematic exploration
of the par() function (if you are interested by the result it's here
http://pbil.univ-lyon1.fr/R/fichestd/tdr75.pdf, the comments are all in
french but it's pure R code under Sweave).
I have a problem with par(tmag) illustrated by the following code:

S4 Dispatching
Is it possible for S4 to (continue) dispatch to a class
created during dispatching? The code below doesn't work;
is this not possible or have I ommitted something?
Concept was to create a SEXP with R_AllocatePtr, give it
a class attribute, and continue dispatch. Example code
below omits multiple parameters that can be different types.
Essentially, any parameter would be converted to an

dyn.load() error: bad external relocation length
R-helpers,
Is there an easy way to call an external (C) program using .C or .Call
without including the code in a package. I know how to do it using
system(), but that doesn't seem to be a permanent or portable solution.
Initially I tried:
.Call('filepath.to.c.function', arg1)
and got this error:

source-only package, but still: Error: package 'simple' was built for powerpc-apple-darwin7.9.0
I have a number simple R functions written for the biologists I work
with. These functions will evolve, and the documentation will get
steadily better. I hope to put them in a package on a local
webserver, along with lots of help files, so that the users can easily
update their installation.
The functions are pure R, with no compiled code, but alias, I cannot figure out
how to build this

R CMD check failure on minimal code
I have a peculiar problem that I'm sure is a simple one, but I can't figure
out what my mistake is. Can someone enlighten me? I have a simple file,
class.R:
##
setClass("abc",representation(a = "character", b = "ANY"))
I have a package directory ExpressCGH1 made with package.skeleton. The
package happily builds and installs, but R CMD check fails with

unexpected par('pin') behaviour
hi everybody,
I noticed the following: in one of my scripts 'layout' is used to
generate a (approx. square) grid of variable dimensions (depending on
no. of input files). if the no. of subplots (grid cells) becomes
moderately large (say > 9) I use a construct like
###layout grid computation and set up occurs here###

R CMD check barfs at 'suggested' package
I have been running R CMD check for the first time on of our own
packages, which otherwise builds, installs and runs just fine. The
package depends on package akima and suggests package multtest;
suggesting multtest is indicated because a) it loads a lot of other
Bioconductor packages, very slowly, and b) it is only needed for one
specific subroutine, which executes require(multtest)

multiple plots with par mfg
Hi,
I'm trying to add points to 2 plots on the fly using par(mfg=vector)
so switch between them. However, the appropriate scales aren't
switched when changing from one plot to another, e.g.
par(mfcol=c(2,1))
plot(1,1, col="blue") # blue plot
plot(1.2,1.2, col="red") # red plot
points(1.1,1.1) # appears to bottom left of red point

However I have read the documentation of the fCalendar package and I have
set my system variable TZ to GMT.

invalid variable type in model.frame within a function
Dear expeRts,
I came across the following error in using model.frame:
# make a data.frame

# spec of formula
mf1=y~x1+x2
# make the model.frame
mf=model.frame(formula=mf1,data=jet,weights=rvar)

bus error on calling nmmin
Hi,
I'm trying to get a toy program making use of nmmin to run

attempt to run my executable, I guess a bus error. I see that someone
else has asked about using nmmin before
