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.

Dear Juan, I don't see what is the problem from your report. Please try to create a minimal but complete reproducible example that does not use the renv package. Perhaps you could use the R debugger (e.g. via options(error=recover)) to find out what is the argument that file.exists() has been called with. And then you could try just to call file.exists() directly with that argument to

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 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

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 "-"

Hi, Main objective: Let Rgui find my ~/.Rprofile and ~/.Renviron files, where ~ is equal to getwd("~"). I have few comments/questions: (A) On my WinXP Pro installation, the system environment variable 'HOME' is not availble to R, e.g. Sys.getenv("HOME") is empty. I believe this is default case (correct me if I'm wrong). However, if I set the "Start

Dear friends - windows R 3.3.3 - sorry to ask a simple question - but I cannot make setwd work properly in scripts In the example below I have made a directory in C (firstdir) and a directory in that (secdir) and the intention is to change directory to the second from the first - it works when I put the entire path but not the tilde - what am I missing? I was around rwf 2.14 as per the help

Estimado Javier Villacampa Gonzáles Si una persona se toma el trabajo de desarrollar y compartir, como es el caso de R, seguramente conoce de problemas que tuvo que decidir mientras escibía el código, y estará agradecido porque hay gente que utiliza su aporte, su trabajo no fué a la nada, todo lo contrario. En mi caso un solo autor tuvo una respuesta negativa para con migo. Javier Marcuzzi

Dear ComRades, I am having the "wrong MD5 checksums" error with every package I try to install. It happened with R 2.11.0, then I updated to R 2.11.1, same thing. sessionInfo() R version 2.11.1 (2010-05-31) i386-pc-mingw32 locale: [1] LC_COLLATE=Spanish_Spain.1252 LC_CTYPE=Spanish_Spain.1252 LC_MONETARY=Spanish_Spain.1252 [4] LC_NUMERIC=C

Thanks for asking. The path where R tries to load the dll from does not exist I think (or the install process deletes it after the error - might this be the case?): C:/Users/wewol/OneDrive/Documents/R/win-library/3.5/grpc/libs/x64/grpc.dll' When I am checking after the error that path is only valid up to: C:/Users/wewol/OneDrive/Documents/R/win-library/3.5/ So maybe (?) the install process

Hello, I found rather surprising the behaviour of POSIXct and POSIXlt classes when combined with min and tapply. The details can be deduced from the script below: ############# Start of the script #################### before <- Sys.time() Sys.sleep( 1 ) now1 <- now2 <- Sys.time() my.times <- c( before, now1, now2 ) class( my.times ) ## [1] "POSIXct"

Dear Ana When you installed R it gave you an option to put a shortcut on the desktop. If you did that then you can start the R GUI by clicking on it. You may need to customise it for your preferences. Specifically it starts R with an option cd-user-docs which I delete and I then alter the starting option to start in the directory I want. You may have different preferences of course. Try

I have encountered a problem with faceted bar plots.
