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

[R] [R-pkgs] amap
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. -- Antoine Lucas Centre de génétique Moléculaire, CNRS 91198 Gif sur Yvette Cedex Tel: (33)1 69 82 38 89 Fax: (33)1 69 82 38 77 ___ R-packages mailing list [EMAIL PROTECTED] https://stat.ethz.ch/mailman/listinfo/r-packages __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
[R] Collineariy Diagnostics
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-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
[R] Stadard errors and boxplots with 632plus error estimator, errorest
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-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
[R] Program Saving
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.
