similar to: only "T" becomes logical colum with read.table

This is a bug both in R and S-plus (in R it's "worse"), I think. Look at this : ma <- cbind(1,1:8); logi <- rep(c(T,F),4) ma[logi,] ##> [,1] [,2] ##> [1,] 1 1 ##> [2,] 1 3 ##> [3,] 1 5 ##> [4,] 1 7 ##-- now the same with [ , drop = FALSE] ## R (-0.50-a3) : ma[logi, drop = F] ##>> Error: invalid subscript type ##

Hello. I'm afraid that I'm missing something very obvious this afternoon... When I add a column to a data.frame (by assigning to a "new" column name a logical vector), I thought that I had (at least) 3 options to do so: R> j <- data.frame (x=1:2) R> j$y <- c(TRUE,FALSE) #assignment 1 R> str(j) `data.frame': 2 obs. of 2 variables: $ x: int 1 2 $ y: logi

Hi, I'm trying to read a .mat file into R (2.11.1) with medium success so far. The file I have is a MATLAB 5.0 MAT-file exported from RiverSurveyor LIVE software (http://www.sontek.com/software.php). I have R.matlab and Rcompression installed and readMat() starts reading the file, as can be seen in verbose mode (hence medium success), but then gives the following error: Error in dim(matrix)

Hello R experts, I have go this data frame: 'data.frame': 1 obs. of 20 variables: $ Anno : chr "PREVISIONI VS TARGET" $ OreTot: num 41 $ GioTot: logi NA $ OrGTot: logi NA $ OreCli: num 99 $ GioCli: logi NA $ OrGCli: logi NA $ OreFor: num -27 $ GioFor: logi NA $ OrGFor: logi NA $ OreOrt: num -18 $ GioOrt: logi NA $ OrGOrt: logi NA $ OreSpo: num -6 $ GioSpo: logi

Hi, I am facing a very weird problem with parallel::mclapply. I have a script which does some data wrangling on an input dataset in parallel and then writes the results to disk. I have been using this script daily for more than one year always on an EC2 instance launched from the same AMI (no updates installed after launch) and processed thousands of different input data sets successfully. I now

Hi Andreas, the error is reported when some child process cannot send results to the master process, which originates from an error returned by write() - when write() returns -1 or 0. The logic around the writing has not changed since R 3.5.2. It should not be related to the printing in the child, only to returning the value. The problem may be originating from the execution environment,

I have test environment to determine what would be best settings. I have been told that enabling zlib compression would be good to save iops on storage. But doing the test now, I get worse results.

Dear R friends. After having some troubles learning how to create a ffdf object, now I find myself having problems saving it. this is the data i´d like to save: str(DATA) List of 3 $ virtual: 'data.frame': 6 obs. of 7 variables: .. $ VirtualVmode : chr "double" "short" "integer" "integer" ... .. $ AsIs : logi FALSE FALSE FALSE

Now that I have a working kvm setup, I thought I'd finally try how Zimbra works. This is mainly some microbenchmarking, so it may not have much to do with actual performance in real life. Setup: - 1GB memory given to kvm (from host's 2GB) - Intel Core 2 6600 (kvm uses only one CPU) - CentOS 5 - 15GB qcow2 image on XFS filesystem - Zimbra 5.0 RC2 RHEL5 x86_64 - Dovecot latest hg,

Hi Andreas, thank you very much, good job finding it was EBADF. Now the question is why the pipe has been closed prematurely; it could be accidentally by R (a race condition in the cleanup code in fork.c) or possibly by some other code running in the same process (maybe the R program itself or some other code it runs). Maybe we can take this off the list and come back when we know the cause

Hi, Installing a source package on Windows using utils::install.packages() with quiet=TRUE fails, while it works with the default quiet = FALSE. The problem seems to be caused by the fact that when quiet = TRUE, stdout and stderr are set to FALSE when calling "R CMD INSTALL" with base::system2() here:

I thought I'd try benchmarking with dbmail (v2.2.4) to see how much slower a SQL backend could actually be. Skip to bottom for the conclusions. Originally I ran the tests with the databases being in XFS filesystem. MySQL's performance was horrible. It went 3-7x faster with ext3. MySQL 5.0.30 backend (innodb): ./imaptest clients=1 - append=100 seed=1 secs=30 msgs=1000000 logout=0

The obvious guess would be that Rstudio is attempting something like redirecting output and getting itself confused. However, it is pretty clearly Their Problem, no?

I want to change the colour of the probability line from the default red to black. I have not been able to find out how to do that. If you look at the code for that function you see this line: logi.curve <-

Hi all, I have this microarray large microarray data set (ALL) from which I would like to subset or extract a set of data based on a factor ($mol.biol). I looked up some example of subsetting in, picked up two commands and tried both but I got error messages as follows > testset <- subset(ALL, ALL$mol.biol %in% c("BCR/ABL","ALL1/AF4")) >> Error in

Hello all, So I am having a puzzling problem. I am working with a 534 x 1065 data frame entitled LocalMaxExpBlue.COR which is completely full of logical values "TRUE" and "FALSE." However, when I attempt to manipulate this data frame, R does not recognize it as logical. Strangely enough, it will identify individual columns (but not rows) as logical. It will also
