baseline fitters
I am pretty pleased with baselines I fit to chromatograms using the
runquantile() function in caTools(v1.6) when its probs parameter is
set to 0.2 and its k parameter to ~1/20th of n (e.g., k ~ 225 for n ~
4500, where n is time series length). This ignores occasional low-
side outliers, and, after baseline subtraction, I can re-adjust any
negative values to zero.
But runquantile's

Release of new version of caMassClass package and new package caT ools
Hi,
A new version of "caMassClass" package was released today. The package
contain pipeline for processing and classification of protein mass spectra
data.
The main change is off-spinning from the library collection of generic
functions into a new package "caTools". This package, which might be useful
to broader group, is much smaller than "caMassClass" and has fewer

This code bellow will calculate average daily wind speed(measurements are

average.

name conflicts
Everyone,
I've got code in my package that uses LogitBoost from the caTools
package. caTools does not have a namespace.
My package also uses loads RWeka, which has a namespace, and also has
a function called LogitBoost.
After loading both packages, how can I be specific about running the
version from caTools (since caTools:::LogitBoost won't work)?
Thanks,
Max

New functions supporting GIF file format in R
Hi,
A minor announcement. I just added two functions for reading and writing GIF
files to my caTools package. Input and output is in the form of standard R
matrices or arrays, and standard R color-maps (palettes). The functions can
read and write both regular GIF images, as well as, multi-frame animated
GIFs. Most of the work is done in C level code (included), so functions do
not use any

shlib problems with Intel compiler
Hi,
I'm encountering trouble compiling caTools_1.17.1.tar.gz and e1071_1.6-4.tar.gz on a Linux system using the Intel compiler suite. 14 other packages I generally use installed without any trouble. I notice both of these trouble packages have a C++ component, so I wonder if that might be the issue. Below, there's information on my platform, compiler, and some diagnostic output showing

Animation of Mandelbrot Set

I was playing with Mandelbrot sets and come up with the following code, I
thought I would share:

C = complex( real=rep(seq(-1.8,0.6, length.out=m), each=m ),

shlib problems with Intel compiler
Hi Martyn,
Thanks for your insight, that seems pretty direct. Unfortunately, I did not compile this version of R (it's on a large supercomputer system and this version of R was installed by the admins). Using "R CMD config", I see the following relevant settings:
DYLIB_LD = icc -std=gnu99
DYLIB_LDFLAGS = -shared -openmp
LDFLAGS = -L/opt/compilers/intel/cce/9.1.039/lib

(Requested) caTools::runmean Patch
Dear Mr. Tuszynski,
I would like to request what I believe would be a beneficial update / patch
to the runmean() function in the caTools package.
Consider the following
R>> x = 1:100
R>> is.integer(x)
[1] TRUE
R>> library(caTools)
R>> head(runmean(x, 5, alg="exact"))
[1] 8.487983e-314 1.060998e-313 1.273197e-313 1.697597e-313 2.121996e-313

Integration of two lines
Hello,
I need to integrate the absolute difference between two lines measured
on different points.
# For example :
x <- seq(0, 1, 1/100)
f_x <- runif(101) + x
y <- seq(0, 1, 1/23)
f_y <- runif(24) + (1 - y)
plot(x, f_x, type="l")
lines(y, f_y)
Then I would like to compute Integral( | f_x - f_y | )dx.
(This is not the same as | Integral(f_x)dx - Integral(f_y)dx |.)

passing field name parameter to function
Hi,
I am passing a data frame and field name to a function. I've figured out how
I can create the formula based on the passed in field name, but I'm
struggling to create a vector based in that field.
for example if I hard code with the actual field name
Y = df$Target, everything works fine.
but if I use the passed in parameter name, it doesn't give me what I want,
Y =

Problems with crossprod
Dear R-users,
I found a strange problem
working with products of two matrices, say:
a <- A[i, ] ; crossprod(a)
where i is a set of integers selecting rows. When i is empty
the result is in a sense random.
After some trials the right answer
(a matrix of zeros) appears.

Survey of "moving window" statistical functions - still looking f or fast mad function
Hi,
First, let me thank Jaroslaw for making this survey. I find it quite
illuminating.
Now the questions:
* the #1 solution below (based on cumsum) is numerically unstable.
Specifically if you do the runmean on a positive vector you can easily
get negative numbers due to rounding errors. Does anyone see a
modification which is free of this deficiency?
* is it possible to optimize the
