Hi Yihui, list.files() returns file names converted to native encoding by Windows, so one needs to use only characters representable in current native encoding for file names. If one wants to be safe, it makes sense to be much stricter than that (only ASCII, and only a subset of it, there is a number of recommendations that can be found online). Using more than that is asking for trouble.

Hi, I think I found a bug in aspell() on Windows. Specifying argument 'dictionaries' for aspell() does not work on Windows, which I believe is because it tries to pass a quoted command line option via shell(). THIS WORKS: # Create a text file to be spell checked > writeLines(c("Hello", "world", "ANOVA"), con="text.txt") # Check it (word

Hi Tomas, I received a report about R 4.0.0 in the knitr package (https://github.com/yihui/knitr/issues/1840), and I think it is related to the issue here. I created a minimal reproducible example below: owd = setwd(tempdir()) z = 'K\u00e4sch.txt' file.create(z) list.files() file.exists(list.files()) setwd(owd) Output: > owd = setwd(tempdir()) > z = 'K\u00e4sch.txt' >

Hi, I have been experiencing a weird behavior when running R in Ubuntu terminal. I don't know exactly what triggers the issue and could not find a 100% reproducible way of getting it. The problem is that sometimes (often after an error is thrown, or after copy/paste of plain text from an editor), the console acts as if its width was limited, breaking lines and makes very difficult to navigate

Hi, on Windows 7 (tested on NTFS file system) and R-devel: 1. file.info("C:/") gives NAs whilst file.exists("C:/") gives TRUE. Instead you have to do file.info("C:/."). 2. Any number of dots will do, e.g. identical(file.info("C:/........."), file.info("C:/.")) == TRUE DETAILS: # C:/ => DISCREPANCY file.exists() and file.info() >

Hi Tomas, Sorry for the false alarm! I did some further testing, and you were right. There was no regression. I suspected it was a regression because the user who reported the issue said his code worked in R 3.6 but not 4.0. I should have tested it more carefully by myself. After I tested it again with the German locale and Chinese locale, respectively, I found that the code worked for both

Hi, I started this post on bioc-devel but this seems to be more general: https://stat.ethz.ch/pipermail/bioc-devel/2013-May/004311.html See reproducible example from Martin below. Thank you.

Hi, another Rd related issue I encountered is that if an error occurs in an \Sexpr in an Rd file, then on get the following error: * checking for portable compilation flags in Makevars ... OK * checking for portable use of $(BLAS_LIBS) and $(LAPACK_LIBS) ... OK * checking examples ... ERROR Error in paste(before, x, after, sep = "") : object 'exfile' not found Execution halted

Hi, when I run R CMD check with flag --as-cran, the process hangs at stage: * checking CRAN incoming feasibility ... I am pretty sure it is a proxy issue. I looked at the check code in the tools package and it seems that the issue is in the local function `.repository_db()` (defined in `tools:::.check_package_CRAN_incoming()`), which eventually calls `url()` with argument

Hi, running install.packages() to install a package from a local repository (i.e., starts with file:///) appears to delete the PACKAGES file that is in the src/contrib/ directory. This happens on a cluster running Scientific Linux release 6.4 (Carbon), but not on my Ubuntu local machine. Subsequent calls to install.packages() complain about src/contrib/PACKAGES not existing, although there still

Thank you very much Steve. Your suggestion works perfectly -- at least with doSEQ, doMC and doMPI.

Hi, I am having troubles sourcing a file from our local network from R. It looks like this file are not properly accessed by 'source', even they can be downloaded with download.file. (See below my settings and some tests I did). I ended up with a work around, but I would like to understand what is going on. Doesn't source/readLines uses the same mechanism as download.file to

Hi: I do not understand the returned value of NA in the following, which is a simplified version of my attempt to convert the start column of the data frame AirQual in the SwissAir package. as.POSIXct(paste('04.04.2004 0',0:3,sep=''),format='%d.%m.%Y %H') [1] "2004-04-04 00:00:00 EST" "2004-04-04 01:00:00 EST" [3] NA

Dear R Developers, I am having an issue with the renv package and R 4.0.1, which I suspect is related to base R and not the renv package itself, as with R 3.6.3 such an "error" does not appear. The error is raised by a file.exists() path, and path "C:\Users\J-tel\Documents", which in R 3.6.3 is read correctly, but in R 4.0.1 fails (Probably because of the "-"

It is a strange behaviour in that I did not expect it... but I am sure there is a simple explanation for it and it'll have to do with the way numbers are stored in R, but it's caught me by surprise and I don't find it obvious. Here's a simplified example reproducing the behaviour I encountered: I create an empty vector, and I fill it with a sequence of numbers: 0, 0.005,

Hi, in R 2.12.1, R CMD check hangs when building a vignette that uses a foreach loop with the doMC parallel backend. This does not happen in R 2.13.1, nor if I use doSEQ instead of doMC. All versions of multicore, doMC and foreach are the same on both my R installations. Has anybody encountered a similar issue? Thank you.

Hi, when mixing newline and backspace characters I get the following output (see below). In the second call, the backspace character is simply not applied. Is this normal behaviour? Thank you. > cat("abc\b") ab> cat("abc\b\n") abc > [[alternative HTML version deleted]]
