...> class(file) [1] "file" "connection" when the connection is open by file <- file(file, "r", encoding = encoding) But this force the following if statement if (chdir && is.character(file) && (path <- dirname(file)) != ".") { owd <- getwd() on.exit(setwd(owd)) setwd(path) } to be FALSE and then non changing of current directory is done. Is this the desired behavior or some bug fix is required? Luca +-----------------------------------------------------------------------+ | Dr. Luca Scrucca...

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' > file.create(z) [1] TRUE > list.files() [1] "K?sch.txt" > file.exists(list.files()) [1] FALSE...

Having recently read about the lack of security of Active X controls, I was wondering if I could get some specifics about its lack of security versus the security of JAVA. Also about the security of JAVA under Linux. I understand that MS''s concept of security is a) investigate the vendor, b) issue a certificate of authority, 3) vendor is now trused to do anything (fox guarding the hen

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 "-"

Hello everyone, I just showed a friend a prototype of a site offering a service I''m trying to sell (sorry, not on the Internet yet - he saw it at my house). His comment: "Looks like it does everything, but also looks pretty ugly. You''re not going to wow anybody with that". Sitting back and thinking about it, he''s dead right - it needs some bling to make it
