I have a vector Pes with 600 elements some of which are NA's. How can I form a vector of the indices of the NA's. for(i in 1:600) if(is.na(Pes[i])) print(i) prints the indices of the NA's but I can't figure out how to put the results in a vector. Thank you very much. Peter B. -- Peter B. Mandeville mandevip at deimos.tc.uaslp.mx Jefe del Depto. de

Happy New Year to all, I am using RW0631 and WIN98. 1. The command DATA only works for the base library. 2. The following code on page 312 of Venables and Ripley 1997 sitka.lme <- lme(size~treat*ordered(Time),random=~1,cluster=~tree,data=Sitka, serial.structure="ar1.continuous",serial.covariate=~Time) produced the following error message Error in lme(size ~ treat *

Kjetil Halvorsen mentioned a book call "S-Poetry in R". I checked with amazon.com and Barnes and Noble but they don't have it listed. Can somebody please give me the complete reference and where it can be obtained. Suggestion: Might it be possible to put a list of the most important and new literature about R, S, and S+ which has a direct bearing on R in the Documentation section

I would like to to know about conversion from jpg file to lss format. I used ppmtolss16. It is giving following errors. for .jpg file: ppmtolss16: stdin is not a raw PPM file at ppmtolss16 line 105, <STDIN> line 1. for .png files: ppmtolss16: stdin is not a raw PPM file at ppmtolss16 line 105, <STDIN> line 1. from .ppm file: ( I converted .jpg file in to .ppm file using irfanview)

Hello R people, i'm trying to implement the Partial Least Squares algorithm called SAMPLS from "J.Comp-Aided Molecular Design", 7 (1993), 587-619. It's faster than the classical PLS algorithm for fat matrix (m>>n). Here's the algorithm from the article of Bush B. L. and Nachbar R.B.: X is the matrix of explanatories proprieties (m*n) , y the matrix of responses, h

Hi: Goal: use R to turn a matrix of 1's and 0's into a corresponding image (e.g. png) of black and white pixels. Why R: Yes, I can do this more efficiently and precisely with a perl module like Image::PBM. Been there, done that many times, etc. (Just humor me. I'm trying to do this with R for a number of reasons.) Problem: Difficult to get a perfect rasterization. There can be appended or removed pixel columns or pixel rows depending on...

Sorry, I didn't read what you said carefully enough -- it's trying to create a system group. Still, looking inside of /etc/group to see what system groups already exist is probably a good idea.

Hi, I am trying to use "read.pnm" from the package "pixmap" to read more than 10 thousand image files in "mydir". > file.list <- dir( "mydir", full=T) > for( i in 1:length(file.list) ) { print(i) x <- read.pnm(file.list[i]) } In the beginning it was fine. But after reading 1020 images or so, the read.pnm function seems to crash on

I observed the same behavior as Edward this morning with R-1.2.2 on Red Hat Linux 7.0. There appears to be a problem with the library in netpbm-9.5-5, even after hunting down the missing shhopt.h that pbmplus.h is looking for. I worked around the problem by compiling e1071 without pbm support (moved pbm.c to pbm.c.bak). Matt Matthew R. Nelson, Ph.D. Director, Information Systems Esperion Therapeutics, Inc.
