Hello, I came across the following behavior, which seems illogical to me. I don't know if it is a bug or if I'm missing something: > all(logical(0)) [1] TRUE > any(logical(0)) [1] FALSE > isTRUE(logical(0)) [1] FALSE This actually came up in practice when I did something like > all( names(x) %in% vec ) as an error-handling, and I was hoping that it would work regardless

Full_Name: Elizabeth Purdom Version: 1.9.1 OS: Windows XP Submission from: (NULL) (171.64.102.199) It would be nice if legend had the option of some default locations you could choose instead of entering specific coordinates, like "topleft", "topright","topcenter", etc. based on par("usr") coordinates. I know I've wanted it so often I've made my

Hi, When I go to the CRAN page to download a new version of R, there are not the same versions available depending on which mirror I pick. When I go to http://cran.cnr.berkeley.edu/, for example, I get 2.2.1, but if I go http://cran.stat.ucla.edu/ the option is 2.2.0 (I'm downloading the Windows base file). Neither refreshing nor clearing my cache changes it. For future reference, I'd

Hi, This is not a bug, but a simple enhancement suggestion: that axis( ) also allow option "col" to take a vector of colors equal to the length of "labels". Currently it allows it, in the sense that there is no error message, but the function will use just the first element of the vector. Example > plot(1:5,exp(1:5),axes=F,type="o") >

Full_Name: Elizabeth Purdom Version: 1.9.1 OS: Windows XP Submission from: (NULL) (171.64.102.199) It would be nice if names(obj) would give slot names as well. Since for many people slots are new, the first thing that happens is you try to access what's in them and can't find how to do it. If you don't know that slotNames() exists, it can be very frustrating. Moreover, if you

Hi, I use sapply very frequently, but I have recently noticed a behavior of sapply which I don't understand and have never seen before. Basically, sapply returns what looks like a matrix, says it a matrix, and appears to let me do matrix things (like transpose). But it is also a list and behaves like a list when I subset it, not a vector (so I can't sort a row for instance). I

Full_Name: Elizabeth Purdom Version: 1.9.1 OS: Windows XP Submission from: (NULL) (171.64.102.199) It would be great if heatmap and/or image had the option of printing a legend bar on it somewhere that would indicate the ranges given by the colors in the heatmap (i.e. a very small image rectangle with the same colors as in the heatmap). Because heatmap is using layout, it seems pretty

Hi, I am trying to use two contributed packages, both of which have a function 'getNames'. So if I load them both they obviously conflict. Currently I manually detach one package and then reload the other to be able to use one function right after another. Is there anything else I can do? Best, Elizabeth

Hi, I am trying to run a batch command on Windows XP and R CMD is not recognized. I get the error, "'R' is not recognized as an internal or external command, operable program or batch file." I have "C:\Program Files\R\rw2010\bin" in my $PATH variable and Rcmd.exe has been installed in that folder. I have restarted the computer to make sure any changes in the $PATH

Dear all, There appears to be a bug in how constrOptim handles ... arguments that are suppose to be passed to optim, according to the documentation. This means you can't get the hessian to be returned, for example (so this is a real problem, and not just a question of mistaken documentation). Looking at the code, it appears that a call to the user-defined f includes the ..., when the ...

Hello, I am running some commands in batch on a server that I SSH into; some of the commands call jpeg(). If I continue to stay signed on (with my xwindows working on my machine) then the jpeg() command works (with a single caveat, below). If I leave it and sign off (with a nohup command in front of my BATCH) then jpeg gives me an error like this: Error in X11(paste("jpeg::",

Hi, This is a question regarding the RWinEdt package for R. I have WinEdt 5.5, RWinEdt 1.7-9, and R 2.6.0 on WindowsXP. Somehow my configuration or start up files between RWinEdt and WinEdt are getting confused. Usually when I open either one, the last files I was working on *with that program* are opened automatically. So if I last used mydoc.tex in WinEdt and myprogram.R in RWinEdt those

Full_Name: Elizabeth Purdom Version: 1.9.1 OS: Windows Submission from: (NULL) (171.64.102.192) hist() fails if encounters 'Inf' value, rather than giving warning and removing. Other graphics, like plot(), don't have this problem. It's actually rather confusing if you are taking the log of data real valued data with a few non-positive numbers. hist() works fine in this situation

Hello, I am running large simulations, which unfortunately I can't really replicate here because the code is so extensive. I rely heavily on mclapply, but I realize that I'm losing data somewhere. There are two worrisome symptoms: 1) I am getting 'NULL' as a return value for some (but not all) elements of the output when I use mclapply, but not if I use lapply > tmp2[1:3]

Hi, I have a student who's R seems to be unable to connect to the internet. I have verified that her computer has internet access that's working fine, but that R is not able to establish connections. For example, she cannot download packages for R from the URL site, cannot source webpages, or read.table from a webpage (all of these give errors of not being able to establish a

Hi, I have my files and R session on a portable hard drive to be able to work across computers since I have some extremely large files. I have just started doing this and generally it works as I expect. But after a while of using my R session, certain types of calls to open connections on the hard drive don't work. But I experience no problems opening/saving files on the portable hard

Hi, I'm not sure if Sweave questions should go to the general list, but it seems to be part of the core R package without a separate maintainer. I am writing a tutorial for R in a latex file. I'd like to use Sweave, since this seems its ideal usage. The problem is that I want to purposefully put errors in and then the output that comes with it in the text of my tutorial. However the

Hi, I've been using the package "graph" in the BioConductor assortment and writing some functions based on its classes. My question is not specific to this package or BioConductor (I think), but it serves as a useful example. I recently wanted to look at the code for the function "edgeMatrix" for the class "graphNEL". Usually I would type > func.foo and

Hi, I have done something (added an unstable package, probably) that has made my help.search function not work. I was wondering if anyone could give me trouble-shooting advice to locate the problem so I don't need to reinstall everything from scratch. I'm in Windows XP, R-2.6.0. The error code is below. Thanks, Elizabeth > help.search("latex") Error in

Hi, I am using eigen to get an eigen decomposition of a square, symmetric matrix. For some reason, I am getting a column in my eigen vectors (the 52nd column out of 601) that is a column of all NAs. I am using the option, symmetric=T for eigen. I just discovered that I do not get this behavior when I use the option EISPACK=T. With EISPACK=T, the 52nd eigenvector is (up to rounding error) a
