similar to: Fwd: Re: choose folder interactively

Dear users, I am looking for a function to choose a folder interactively, just like file.choose() but for a folder. I have found tcltk::tk_choose.dir() but R hangs when I try to do anything and I have to force exit. I've tried to reinstall tcltk with install.packages(), but "package ?tcltk? is not available (for R version 2.15.2)" even though it's already installed on my

Dear users, I have a weird questions. A friend of mine, some years ago, supposedly trying to access help files without Internet connection, got something like this error message: "The Pythia is not available, please go to Delphi" When I've heard about it, I found it very funny and I'd like to be able to get it. Does anyone of you know how to get this error message again?

Dear users, I'm trying to learn how to use the "...". I have written a function (simplified here) that uses doBy::summaryBy(): # 'dat' is a data.frame from which the aggregation is computed # 'vec_cat' is a integer vector defining which columns of the data.frame should be use on the right side of the formula # 'stat_fun' is the function that will be run to

Hi Philippe and R community, I am trying to use some functions from the svDialogs package but I get some werid errors I do not understand: > library(svDialogs) > m_list <- as.list(1:10) > guiDlgDoubleList(m_list, m_list) Error in guiDlgDoubleList(m_list, m_list) : Not yet implemented! > guiDlgList(m_list) Error in guiDlgList(m_list) : couldn't find function

Dear list, I'm quite confused when interpreting results from a mixed linear model. For example, working on Iris data frame, I want to know the effect of species on slope of the model "Petal.Length~Sepal.Length" I write this : data(iris) reg01 <- lm(Petal.Length~Sepal.Length + Sepal.Length:Species, data=iris) summary(reg01) It gives me a summary table with lm for the first

Dear Jim, Here is again exactly what I did and with the output of Rprof (with this reduced dataset and with a simpler function, it is here much faster than in real life). Thanks you again for your help! ## CODE ## mydata1<- structure(list(species = structure(1:8, .Label = c("alsen","gogor", "loalb", "mafas", "pacyn", "patro",

Hi everybody ! I'm new to R (used to Matlab ...) and I 'd like to use R at home ...

After the last round of patches to febootstrap, the image-based test in libguestfs still failed. It turned out that this happens because Debian started replacing /var/run and /var/lock with symlinks that point to a tmpfs mounted to /run. The symlinks were copied to the appliance but /run/lock did not exist, so pvcreate refused to run (script 'images/guest-aux/make-debian-img.sh'). After I

Hi Ghislain, I think you might be comparing two versions of R with different BLAS implementations, one that is single threaded (is your 3.3.2 used with reference blas?) and one that is multi threaded (3.4.1 with openblas). Could you check with "perf"? E.g. run your benchmark with "perf record" in both cases and you should see the names of the hot BLAS functions and this

Dear all, As the object of this mail suggests, the methods package is not loaded by default in R2.13 when using Rscript whereas it is loaded when using an interactive session. An example with the metafor package : library(metafor) example(addpoly.rma) this works in an interaction R shell, but put it in a .R file and use it with Rscript, it won't work until you added library(methods)

Hi Ghislain, The documentation at https://cran.r-project.org/doc/manuals/r-release/R-admin.html#BLAS provides a fair bit of information. What specifically would you like to see added?

Dear All, Sorry for asking a newbie question. I want to ask how to import 1000 datasets whose file names are labelled from data1.dat to data1000.dat into R so that they are named M[1, , ] to M[1000, , ] accordingly. Thank you very much. Best Regards, Ray [[alternative HTML version deleted]]

Hi everyone I would like to know if it's possible to prevent many loggings on many computers from only one user? I have user who opened 12 computers, logged on those 12 computers and ran boinc-client on those 12 computers... I want to prevent this kind of behaviour... Thanks in advance.

Dear R users, I would like to draw map and import it in maptools/spatstat packages. The 'raw data' I have come from a web page (<map>...</map>) and are basically a list of coordinates of a polygon. I would like to know how to import them in R; I checked the maptools packages, but all the examples use existing .dbf files. I just have a (serie of) text file(s) looking like

Hi Ista, Maybe a little comment in the 'matmult {base}' doc page or on the 'options {base}' in the field 'matprod' would be useful to remind users to be cautious regarding BLAS multi-threading? I understand why this is a BLAS related issue and not directly an R related issue. Nonetheless, my concern was for non-advanced R users, that may don't even know what BLAS

Dear R Core Team, I wish to report what can be viewed as a bug or at least a strange behavior in R-3.4.1. I ask my question here (as recommended on https://www.r-project.org/bugs.html) since I am not member of the R's Bugzilla. When running 'R --vanilla' from the command line, the standard matrix product is by default based on BLAS and multi-threaded on all cores available on
