I am planing to buy several machines with 2 GB RAM.
Is R able to use this much memory?
Thanks

standing ovations
I think this is a moment to lean back from daily business, details or
whatsoever and appreciate the impressive achievment of Ross, Robert and the
R-core team. Incredible!
They created an impressive and extremely useful software, for teaching,
research and more. Besides these direct practical benefits, I think this
project is more: it gives an outstanding example of international
cooperation and

Large data sets and aggregation
I've noticed quite a few messages relating to large data sets bedeviling
R users, and having just had to program my way through one that actually
caused a "Bus error" when I tried to read it in, I'd like to ask two
questions.
1) Are there any facilities for aggregation of data in R?
( I admit that this will not do much for the large data set problem
immediately)
2) Is there any

Newsgroup - another try?
As nobody seems to answer my request, I simply post it again.
Is there any reason why the r-help-mailinglist should not be converted to a
newsgroup?
These were the advantages of a newsgroup I mentioned earlier:
-) you can easily search the archives
-) the discussion is faster (I experience that the R-mailinglist has a lag
of about 1 to 2 hours (not for everyone!!!). When I ask a question, I get

AW: Newsgroup - another try?
| I can think of two disadvantages of a newsgroup
|
| 1) Access
| Everyone with an email address can sub_scribe to the R mailing lists.
| However, not everyone has a news feed. I don't.
Everyone who has access to the internet can also have a news-account. There
are a lot of good free news-servers (most of the time hosted by
universities), and on the client-site you can often use your

R-alpha: fft does not act as described in help(fft)
Hello!
thank you for your efforts creating R!
While preparing the next lessons I found that I had
to multiply with 1/length(x) by hand if I want to
get the inverse Fouriertransform.
The help states it will do it by itself.
Version R-0.60.1, Linux
Seems to be pretty easy to correct either the fft or :-) the help(fft)!

chull() wanted?
Hello!
Is there someone already working on an implementation of Splus'
chull() function for R?
If not, I would like volunteer to try it.
For my "Diplom" I implemented convex peeling in C (some time ago),
using an O(n log(n)) algorithm, so it probably will prove relatively easy to
use that code for a R-function.
Well, as least as easy as any programming tends to be. :-)

multiple correlation?
I'm looking for a function for the 'multiple correlation' but can not figure
out what it is called in R by using the html search function. Maybe it is
called in another way in english? I only know the german term?
Can anyone help me?

short way
i want to replace certain values of a matrix.
i know how to replace them when the values are in a vector.
i tried the same way for a matrix and got this answer:
la[la==0]<-1
Error in [<-.data.frame(*tmp*, la == 0, value = 1) :
matrix subscripts not allowed in replacement
i found a way to do this with "for()",
but i think this is the worst way to do it.

winedt (PR#1033)
i don't know, whether this is a bug or it is intended:
when using winedt and R together it works perfectly, as long as R is run in
mdi (multiple window mode). When you switch to sdi (single window mode)
winedt, sends no command at all: no history, paste, source or script.

read.table
When I read a table (the dimnames of the table are numbers), R reads the
column names as: X plus the number (X1,X2,X3,...) and the rownames as the
numbers (1,2,3,...)
How can I suppress this action?
The code and the output:
^^^^^^^^^^^^^^^^^^^^^^^^
> r2<-read.table("h:\\matrix",header=T,dec=",",na.strings="-99")
> dimnames(r2)

type missmatch in ?par
under 'mfg' the second paragraph says:
[.]the form `c(i, j, nr, nc)' is also accepted, when `nc' and `nc' should be
the current number of rows and number of columns. [.]
it should be 'nr' and 'nc' instead of 'nc and 'nc'

Problem installing R on openSUSE 10.3
Dear All,
I am trying to install R 2.7 on my openSUSE 10.3. I have faithfully followed instruction at http://cran.r-project.org/bin/linux/suse/ReadMe.txt. I have downloaded all the RPMs but still R complains about:
libtcl8.4.so is needed by R-base-2.7.1-6.1.i586
I searched for this library and found a one, tcl-8.4.15-22.i586.rpm at openSUSE distribution site and installed. But R still complains

Dear R-friends,
i just look at http://www.statistik.uni-dortmund.de/leute/ligges.htm to
download scatterplot3 and saw a write and read wav-files library. So i
wondered if R can play wav-files. This would be very practical, espacially
when you do some long computations.
If not, can R play a system beep or something like that?
Thanks,
Thomas

SQL and R
dear Members,
I have recently started studying SQL and MySQL. My question is, what exactly is SQL used for? That is, whatever can be done by SQL, like subsetting and filtering of data sets, can also be done by R. What's, then, the advantage of SQL? It is OK if you tag this question as offtopic, but I could'nt find any info on the web. Can you please refer me to
