[R] [R-pkgs] gmp: bigintegers with matrix computation

2006-06-30 Thread Antoine
Dear all,

gmp package is now available on cran with version 0.4

Aim of gmp is to provide a lot a function to manipulate big integers, big 
rationals and last but not least big integers in Z/nZ (modulo n)

We add in last version support for matrix computation (standards operators, + * 
- / %*% ...) and inversion matrix (solve):
in Z/nZ if matrix defined in Z/nZ
with rationals (absolute precision) if not.

Best Regards,

Antoine Lucas.

[R] [R-pkgs] amap

2006-01-25 Thread Antoine Lucas
Dear R users,


Version 0.7-1 of the amap package has been uploaded to CRAN.

   Amap package includes standard hierarchical
   clustering and k-means. We optimize implementation
   (with a parallelized hierarchical clustering) and
   allow the possibility of using different distances like
   Eulidean or Spearman (rank-based metric).

   We implement a principal component analysis (with robusts methods).

News of version 0.7-1: a new method of clustering optimal partiton

A major advantage of the method is that the number K of classes 
is computed from the data, and ONLY from the data.

[R] Collineariy Diagnostics

2005-09-13 Thread Antoine de Bary
Hi, and thanks for your help

in order to do collinearity analysis I downloaded the perturb package. I run
a lm (regression) and on that the ³calldiag² commad to get condition numbers
but i get the following message: the variable XY with modus ³numeric² was
not found (it does the same with all predictors despite all variables are
numeric and exists).

Can anyone tell me how can I go arround this problem? Is there another way
to have ³condition numbers²? What about VIF?

Please return message to: [EMAIL PROTECTED]

Thanks a lot

Antoine

[R] Stadard errors and boxplots with 632plus error estimator, errorest

2005-01-10 Thread Antoine Beuchat
Dear R-users, 
 
I'd like to estimate standard errors (for lda) and make a boxplot with the
632plus and boot error estimators included in package ipred (method:
errorest). The boot estimator returns only a standard deviation but not
the whole error data.

Thank you in advance,
regards, 
Antoine

[R] Program Saving

2003-11-13 Thread Marc-Antoine Vaillant
Hi,

I have a very simple question. If a want to save a whole program (say more than 5 
command lines), how can I proceed without each time using the command history (that 
allow me to recall previously saved command, but which is to long if you want to 
recall more than 5 command lines), or without saving to a text file and use copy/paste 
when I open a new R session (but in fact this doesn't work since when you copy your 
program to a text file, you copy the  or the + , and when you paste it back to a 
new R command sheet, you get syntax error since you now have double  () and 
double + (++) at each line.

Do they have something simple like in any other program, that consist of saving the 
command sheet under say Program X. Program X will become a simple file that I can 
reopened any time I want and each time I open it, I will have in front of me all the 
previous saved command, (including error, I don't care), in order that I don't have to 
recall anything when the program X is opened.

Thanks

Marc-Antoine Vaillant
