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

(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

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 externa...

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 plat...

Animation of Mandelbrot Set
Hi,
I was playing with Mandelbrot sets and come up with the following code, I
thought I would share:
library(fields) # for tim.colors
library(caTools) # for write.gif
m = 400 # grid size
C = complex( real=rep(seq(-1.8,0.6, length.out=m), each=m ),
imag=rep(seq(-1.2,1.2, length.out=m), m ) )
C = matrix(C,m,m)
Z = 0
X = array(0, c(m,m,20))
for (k in 1:20) {
Z = Z^2+C
X[,,k] = exp(-abs(Z))
}

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 comput...

runsd {caTools} crashes R 64bit on winxp64bit with a very large vector
Hello
I have a 3.5 million elements numeric vector x. I'm trying to calculate the
rolling std dev of the previous 144 elements.
rsd144<-runsd(x, 144, center=0, endrule="NA")
this crashes R (ie on the console disappears and the Rgui.exe process is not
there anymore)
with smaller vectors, the crash does not occur.

Help on calculating AUC with caTools trapz(a,b) command
Dear All,
I have the following example:
a <-matrix(c(1:100),ncol=10)
b <-matrix(c(2,4,6,8,10,12,14,16,18,20))
trapz(b,a)
will give me a result of 99, which it seems to me is the AUC of the 1st column only. Is it possible to get the AUC results by columns of "a" using the same "b" values in the calculations as opposed to just generating the result for the 1st

Integration of two lines
...dx |.)
Computing this integral looks non trivial. I guess I should interpolate
the points of f_y over x and integrate both lines on these intervals.
Even then I would miss points where the lines cross.
There are functions to integrate below *one* line (I'm thinking about
the trapz function in caTools).
Do you know if there is a function to do this integration properly with
two lines (and especially their absolute difference)?

Xavier
