Problem with & question about \preformatted in .Rd
Hi,
The "\preformatted" environment in Rd files doesn't seem to escape
long sequences of backslashes properly when converted to pdf (LaTeX)
documentation. I'm running R version 2.14 (from subversion, revision
57751) on Linux (RHEL). Here's an example from the command line:

error in f(x,...)
Dear all,
I tried once to create one variable called bip such that:
bip <- cip + (1/f(cip))*fi(f,cip)
And this was working.
But now, doing the same thing I did before, the software shows me the
following message:
Error in f(x, ...) : unused argument(s) (subdivision = 2000)
I have the variable cip and the variable bip should be created such that:
Fn <- ecdf(cip)
f <- function(x) {(1 -

Repeated Procedures
Dear Friends,
Using package Vegan, I need to calculate Shannons Diversity index
and Pielou's Evenness for a set of 20 study areas. Each area is
represented by a matrix of 25 sample plots x tree species. The code is
as following, where data stands for the data matrix of any of the 20
areas:
S <- specnumber(data)
H <- diversity(data)
J <- H/log(S)
I indexed the 20 areas by a

Regression using mapply?
Hi,
I have huge matrices in which the response variable is in the first
column and the regressors are in the other columns. What I wanted to do
now is something like this:
#this is just to get an example-matrix
DataMatrix <- rep(1,1000);
Disturbance <- rnorm(900);
DataMatrix[101:1000] <- DataMatrix[101:1000]+Disturbance;
DataMatrix <- matrix(DataMatrix,ncol=10,nrow=100);

Numerical Derivatives in R
Hi,
Suppose I have an arbitrary function:
arbfun<-function(x) {...}
Is there a robust implementation of a numerical derivative routine in R
which I can use to take it's derivative ? Something a bit more than
simple division by delta of the difference of evaluating the function at
x and x+delta...
Perhaps there is a way to do this using D or deriv but I could not
figure it out.

Plotting observed vs. fitted values
Dear Wiza[R]ds,
I am very grateful to Duncan Murdoch for his assistance with this problem.
His help was invaluable. However, the problem has become a little more
complicated for me. Now, in each plot, I need to plot the observed and
fitted values of a supine and upright posture experiment. Here is what I
have and how far I got.

Troubles with DBI's dbWriteTable in RMySQL

How to increase the for() loop speed?
Dear R users,
I would like to know if there is a way to increase the for() loop speed
because in my routine the calculations are too slow.
Best regards.

legend problem
Dear R users,
I have been plotting several graphics in only one page. I intend to plot
only one legend in each page.
Since the graphics are inside a loop I have to do it automatically.
The main problem is that inside the loop I work with differente types of
variables, I mean , the range is different for each one.
I have already tried :

Output Graphics GIF
Dear R users,
How could I managed graphics in GIF format? What I have been doing is
graphics in *.ps or *.eps and after I convert them using CONVERT (from
ImageMagick) but the output quality is not good. Since these graphics will
be use for other users they must have a better image quality.
I really appreciate any help,

legalities of streaming
Basically, to legally broadcast music you must:
A) Obtain permissions from the copyright holder (usually the publisher, record
label) of the *composition*. ASCAP, BMI, and SESAC offer compulsory licenses
for all of the artists they represent, fees based upon roughly how many
listeners your station has & how many songs in your broadcast are by
artists/composers they represent.

Win32 and ELF created files are different
Hi everyone,
I was fiddling with FLAC executable on Linux and also making FLAC files with foobar2000 under WINE. I was using the same exact options for both linux native executable and flac.exe through foobar2000. But I have noticed something: The FLAC files themselves created from flac.exe and flac(ELF) are not bit identical. They differ in something (Not audio data).

multiple plots - editing ggplot2 plot
Hi All,
I am trying to build a composite plot, with multiple categories, using
ggplot2.
In principle, it could be done using facetting, but I do not seem to be able
to get past the defaults, so I try building each plot separately, then
putting them all together using frameGrob and placeGrob.
For this, I need to know how to:
1) format the legend with a different layout (e.g 2 rows by 2 columns,
