similar to: strange behavior in data frames with duplicated column names

Dear R list, I have discovered a seemingly peculiar feature when using a matrix to index itself (yes, this is strange code, which I have now modified to be more reasonable). #this makes sense s <- matrix(1:3,nrow=1) s[s] #all three elements are shown #but when I try s <- matrix(1:2,nrow=1) s[1] #fine, the first element is shown s[2] #fine, the second element is

Dear fellow developers, Is there an easy way to determine how big my packages (psych and psychTools) will be on various versions of CRAN? I have been running into the dread 'you are bigger than 5 MB" message for some installations of R on CRAN but not others. The particular problem seems to be some of the mac versions (specifically r-oldrel-macos-arm64 and r-release-macos-X64 ) When

Dear list A strange bug in the psych package is due to the behavior of the diag function: It gives the expected values for 1, a vector (-1,1), but not for -1 Is this a known feature? > diag(1) [,1] [1,] 1 > diag(c(-1,1)) [,1] [,2] [1,] -1 0 [2,] 0 1 > diag(-1) Error in diag(-1) : invalid 'nrow' value (< 0) Bill William Revelle

I would say it is a mis-feature. If the 'x' argument of diag() is a vector of length 1, then it creates an identity matrix of that size, instead of creating a 1x1 matrix with the given value: ? diag(3) [,1] [,2] [,3] [1,] 1 0 0 [2,] 0 1 0 [3,] 0 0 1 Of course this makes it cumbersome to use diag() in a package, when you are not sure if the input vector is

Dear R developers, Is there a way to pretest a package on the Solaris-sparc and solaris-x86 systems equivalent to the win-builder check? My psych package (1.1.10 and 1.1.11) passes all checks for the Mac on my system, on the win-builder checking system supported by Uwe, and then passes Kurt's tests to install on CRAN. But it then fails when being built for the solaris systems. Rather

Dear friends, How do I stop partial matching of list names? e.g., x <- list(AAAA="aaaaa", BBBBB="bbbbb") is.null(x$A) #returns FALSE even though there is no element A. if(is.null(x$A)) {result <- x$BBBB} else {result <- x$A} result #is aaaa even though there is no x$A element x <- list(CCCC="aaaaa", BBBBB="bbbbb") if(is.null(x$A))

This still seems to be the case. I tried uploading the most recent version of psych and got as far as the Step 3 page which says that it has sent out an email. However, although normally this step takes agout 1 minute, nothing has happened for 16 hours. Should we just use the old system of uploading to the ftp site and sending a confirming email? Thanks of course to the CRAN maintainers

Dear friends, I have just gotten a strange error message back from Uwe saying that the most recent version of psych failed to pass R CMD check for Windows. The error message was less than helpful, in that it seems to have failed when trying to include the Rcpp library, which I do not directly call. (see below) "* using log directory

Dear list, I am trying to prepare a handout showing how to use R for factor analysis. As part of the exercise I want to save a correlation matrix on a tutorial web page. I can save with no problem (saving locally and then transferring to the web site). Although I can load() the local file, I am having problems getting loadURL to read the remote file. I have tried saving it as an ascii

Dear list friends I fail to understand how to find means for multiple groups using the by() function. Help would be appreciated. Thanks. Bill x <- runif(20,0,10) group <- rep(c("A","B"),10) df <-data.frame(x,group) #df #show the data rm(x,group) attach(df) sd(x) # sd is defined mean(x) #so is mean by(x,group,sd) #this works for both groups

Dear list Maybe someone can help with the following problem: I have a source file containing the following code for plotting: pdf(file = 'data/mario/boxplot.pdf') bwplot(sig100 ~ target | group, data = fish, main = 'Boxplot der Signale in 100 Zellen nach Gruppe', xlab = '', ylab = 'Anzahl der Signale') dev.off() pdf(file = 'data/mario/xyplot.pdf')

Running the Chapter 4 examples in Pinheiro & Bates' "Mixed-Effects Models in S and S-PLUS" (2000), I get a message that the default optimizer doesn't converge, but using "optim" for the optimizer results in convergence: > > library(nlme) > > fm1IGF.lis <- lmList(IGF) > > fm1IGF.lme <- lme(fm1IGF.lis) > Error in lme.formula(fixed =

The .Renviron and .First functions do not seem to work the same way on a Mac OS 10.4 as on a Windows XP machine. From working in Windows I am used to creating a new directory for each data analysis project. In the new directory I place First, an .Renviron file consisting of the following text: R_HISTFILE="history.txt" R_HISTSIZE=1000000 Second, an .RData file containing a .First

Hi all, What are current methods people use in R to identify mis-spelled column names when selecting columns from a data frame? Alice Johnson recently tackled this issue (see [BioC] posting below). Due to a mis-spelled column name ("FileName" instead of "Filename") which produced no warning, Alice spent a fair amount of time tracking down this bug. With my fumbling fingers

Hi, I just upgraded to Ruby 1.8.6 on my Mac development machine and here''s what I''m seeing when I try to run mongrel (I have the latest version of mongrel + fastthread installed). It seems to be an OS/X thing, because this same combo works fine on our Linux server. Here''s the error, have you guys seen anything like this?: ** Starting Mongrel listening at

Dear all, I can't get the labels slot in ICLUST to accept a character vector. library(psych) test.data <- Harman74.cor$cov ic.out <- ICLUST(test.data,nclusters =4,labels=letters[1:ncol(test.data)]) ##?Error in !labels : invalid argument type ic.out <- ICLUST(test.data,nclusters =4,labels=1:ncol(test.data)) ## OK Any ideas?

Hi all, I've had one of my most miserable R weeks in memory. I'm trying to deal with huge datasets (>1GB each) but am running up against those pesky memory limits. The libraries filehash and g.data are not very suitable for what I need. I haven't gotten into the sql thing yet. Most recently I've been trying to install the new package ff (not yet on the CRAN repository). I

Dear list, I am having a segfault while working with large lists in R 2.4.1 patched (64-bit compilation) on an apple xserve xeon with 16GB RAM (I don't know if this is reproducible on other configs since this is the only computer with enough memory I have access to...) You will find below a simple somewhat reproducible (usually it crashes around 5.5GB of vsize, sometimes it gets into
