similar to: library() - Error: Package foo was built for Win32

Full_Name: Henrik Bengtsson Version: 1.6.0, 1.5.1 OS: WinXP Pro Submission from: (NULL) (128.250.252.82) The following example, which I tested on both R v1.5.1 and R v1.6.0 on WinXP Pro, shows the problem I encountered when trying to use the class attribute of an environment: # Define method print() for class Environment C print(e) # gives: # [1] "An Environment!" # Exit [R]

Is there a way of calling the method of the root class directly? Here is an example explaing my question. Everything relates to S3/UseMethod classes and methods. I have an object x of class MicroarrayMatrix, which inherits from class Matrix. The "core" object of x is a simple matrix. In other words, I basically have x <- matrix(logratios, ncol=nbrOfSpots, nrow=nbrOfSlides)

Hi, I've been learning how to use R TclTk in Windows over the last few months. I have recently put together a collection of examples of some common widgets and their corresponding R code, at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ I would be interested in any feedback - Is it useful? Does it contain any significant errors or bad coding style? Does anyone else want to

I am not sure if what I am asking below should be discussed under r-help or r-devel, so please feel free to move over to r-devel. This is a spin off from Gordon Smyth's question about generic functions and Robert Gentleman's reply. I have tried to raise the question before and I am sure this has been discussed by others, but never on the r-help list what I can see. My concern is that

Thanks Peter, I've started a new R session (in Windows) and managed to get both ways working now : ### THIS WORKS !!! ### library(tcltk) tclRequire("IWidgets") tt<-tktoplevel() combo <- tkwidget(tt,"iwidgets::combobox") tkpack(combo) ### AND THIS WORKS TOO !!! ### tt<-tktoplevel() win <- .Tk.subwin(tt)

Hi, a few comments below. First, from my experience and troubleshooting similar reports from others, a returned NULL from parallel::mclapply() is often because the corresponding child process crashed/died. However, when this happens you should see a warning, e.g. > y <- parallel::mclapply(1:2, FUN = function(x) if (x == 2) quit("no") else x) Warning message: In

Hi, I am trying to create a drop-down combobox in R TclTk. The following works fine for a ListBox but fails for a combobox: ################# THIS WORKS FINE - CREATES AN EMPTY LISTBOX ## tt<-tktoplevel() win <- .Tk.subwin(tt) .Tcl(paste("listbox",.Tk.ID(win),.Tcl.args())) tkpack(win) ################## THIS FAILS - ATTEMPTS TO CREATE A COMBOBOX ## tt<-tktoplevel() win

Hi, I have successfully installed R 1.7.0 and ActiveTcl 8.4.2.0 in Windows 2000. Yes, I know that Tcl is already bundled with R 1.7.0, but I want to use the iwidgets package to create a drop-down listbox, and I don't think iwidgets is included in the bundled R 1.7.0/TclTk installation package. I have set the environment variables TCL_LIBRARY and MY_TCLTK to the directory where I

First of all, I haven't followed the discussion about the new/upcoming name space support in R so I do not know the purposes or requirements for it, neither its design, and I can only guess. I found the (initial?) notes by Luke Tierney on the Developers Page. Are there any other references? Since it seems that the current implementation (R v1.6.2) of name spaces is a "trial" version

Hi Ivan, An apology, I was away for quite a bit. To reproduce the setup: I have been using the default GCC in RHEL 9.1. gcc -v Using built-in specs.

Dear R users, I have just upgraded R v1.5.0 to v1.6.1 for Windows but have trouble loading my library of R only functions (no C calls). After examining the "library" script this difference was found: (v1.5.0) which.lib.loc <- dirname(pkgpath) descfile <- system.file("DESCRIPTION", package = package, lib.loc = which.lib.loc) if

Do NOT use mcparallel() in packages except as a non-default option that user can set for the reasons Henrik explained. Multicore is intended for HPC applications that need to use many cores for computing-heavy jobs, but it does not play well with RStudio and more importantly you don't know the resource available so only the user can tell you when it's safe to use. Multi-core machines are

Dear all, I would like to use data in .netcdf format and for those I have to use the netCDF or ncdf packages. Problem : these packages don't seem to work : "Error in testRversion(descfields) : This package has not been installed properly See the Note in ?library" (with netCDF package) Does anybody have the same problems with these packages ? Is there any

Hi Peter and others, If it helps, I wrote a small function glm.scoretest() for the statmod package on CRAN to compute score tests from glm fits. The score test for adding a covariate, or any set of covariates, can be extracted very neatly from the standard glm output, although you probably already know that.

Hi all, I seem to be getting segfaults when attempting to build R 4.4.0 on RHEL 9.1 (5.14.0-162.23.1.el9_1.x86_64). Interestingly, it seems to build ok on Rocky 9.1 and 9.3. This is the trace: make[3]: Entering directory '/home/esteva.m/R/R-4.4.0/src/library/grDevices' building package 'grDevices' make[4]: Entering directory

Yes I am running on Rstudio 1.2.5033. I was also running this code without error on Ubuntu in Rstudio. Checking again on the terminal and it does indeed work fine even with large data.frames. Any idea as to what interaction between Rstudio and mclapply causes this? Thanks, Shian On 28 Apr 2020, at 7:29 pm, Simon Urbanek <simon.urbanek at R-project.org<mailto:simon.urbanek at

This is just a suggestion/wish that it would be nice for the F-distribution functions to recognize limiting cases for infinite degrees of freedom, as the t-distribution functions already do. The t-distribution functions recognize that df=Inf is equivalent to the standard normal distribution: > pt(1,df=Inf) [1] 0.8413447 > pnorm(1) [1] 0.8413447 On the other hand, pf() will accept Inf

What do I need to do to load the RMySQL library on Win 2K using version 1.8.1 I have Mysql v4.0.16 up and running on the local machine with several databases running fine. Using RGUI I have loaded RMySQL and an appropriate directory structure has appeared under C:\Program Files\R\rw1081\library\RMySQL I have added C:\Program Files\R\rw1081\library\RMySQL\inst\libs to my path variable so that

In R 2.1.1, the default behaviour of scan() was changed to process all C-style escapes, even when a delimiter was specified using the 'sep' argument. A new argument 'allowEscapes' was introduced to turn this processing off. Because read.table() calls scan(), read.table() inherits the new default behaviour of scan() but without a way to turn it off. For example, reading a file
