similar to: which() does not handle NAs in named vectors. (PR#226)

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

Dear Helpers, I just started working with R and I'm a bit overloaded with information. My data is from marsupials reindroduced in a area. I have weight(wt), hind foot lenghts(pes) as continues variables and origin and gender as categorial. condition is just the residuals i took from the model. > names(dat1) [1] "wt" "pes" "origin" "gender"

Hello Helpers, I have some problems with fitting the model for my data... -->my Literatur says (crawley testbook)= Non-normality of errors-->I get a banana shape Q-Q plot with opening of banana downwards Structure of data: origin wt pes gender 1 wild 5.35 147.0 male 2 wild 5.90 148.0 male 3 wild 6.00 156.0 male 4 wild 7.50 157.0 male 5 wild 5.90

Hi there! I have a serious issue! I tried installing a game (PES 2010) and then, because it was not running, I decided to remove the application and upgrading to wine 1.1.33. So I did and then I restarted setup.exe, but now it brings me to the unistall prompt of the game, as if I had pes installed yet! To remove it, I oreviously used the "remove wine apps" tool, but after that the game

Hi all, I was conducting a meta-analysis of single proportions(i.e. without a control group) using the metafor package. When I performed a classic fail-safe N, I noticed that the result (the number of missing studies that would bring p-value to the alpha, to be exact)was different than that I got in Comprehensive Meta-Analysis Version 2.0. I wonder why R and CMA got different results. *Below is

The problem with POSIXt is that you must consider timezones and daylight vs. standard time issues even if you don't want to. This violates modularity (viz. your routines becomes coupled to unrelated information) and leads to subtle errors where different routines are assuming different time zones. The problem is that the time, date, day of the week, month, etc. of a date depend on its

[sending this to R-devel, since it may be of general interest and could possibly lead to better instructions in the "R-exts" manual] Is this another case where only .Call() or .External() [or a fudge factor] solve my problem? Following situation: I use dyn.loaded C code to compute a recursive tree structure from my data. Beforehand I don't know how big the tree will

Greetings, Cohen, Cohen, West, and Aiken 2003 (Applied Multiple Regression-Correlation Analysis for the Behavioral Sciences, Third Edition) on page 273 state the covariance matrix of the regression coefficients is provided by standard programs for multiple regression, including SAS, SPSS, and SYSTAT. How can it be calculated with R. Thank you very much. pbm Peter B. Mandeville cel:

Indeed, there is no file named "dlltool" anywhere around here! So, at last I am beginning to suspect that my collection of tools is incomplete. What I have got is "rw1020sp.zip" and "http://www.stats.ox.ac.uk/pub/bdr/RWin/tools.zip". These are properly istalled, I think. readme.packages says "If your package has no C nor Fortran nor C++ sources, see `Simple

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:

Hello, happy new year to all. The new Year gave me a new computer with Win98 and promptly I installed R on it. I created a directory R, with subdirectories gcc, perl,bin, helpwrk and rw1040. I got rw1040 from BDR place, the rest were gotter from the internet in the last week of the year, i.e. they are the newest versions. I modified autoexec.bat to put gcc\bin, perl\bin, etc in the path. I put the

CRAN has a package of mine in upload limbo because it failed UBSAN. I am not entirely ignorant on the topic of sanitizers and SAN / ASAN / UBSAN; we created not one but two Docker containers with ASAN and USBAN: https://registry.hub.docker.com/u/rocker/r-devel-san/ https://registry.hub.docker.com/u/rocker/r-devel-ubsan-clang/ as well as predecessors to them in earlier Docker repos. Yet I
