Re: [Rd] User Input
If you use S4 objects then have a look at ?setValidity

[Rd] Why no support for 3-digit HEX colours?
When specifying an RGB colour in R, is there a strong reason not to accept 3-character HEX codes? In CSS and many other languages, a colour of "#ABC" is automatically converted to "#AABBCC", and I was wondering if R could support that as well, or if it was a conscious decision to not support it. --- http://deanattali.com [[alternative HTML version deleted]] __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

[Rd] suggestion: better support for https CRAN mirrors
Hello, I see that https CRAN mirrors are starting to pop up, as per this post at https://support.rstudio.com/hc/en-us/articles/206827897-Secure-Package-Downloads-for-R However, trying to use one of these mirrors without changing the default download.file.method option gives me errors > Warning: unable to access index for repository > https://cran.rstudio.com/src/contrib > Warning: unable to access index for repository > https://cran.rstudio.com/bin/macosx/mavericks/contrib/3.2 I don’t mind just choosing an http mirror but when prompted to select a mirror, there is no distinction made in the mirror listing between http and https mirrors. It would be nice if https mirrors were hidden when the current environment doesn’t support them. Alternatively, at least make a distinction between http and https in the mirror listing. They currently just look like duplicates. I think this is a pretty trivial change but would help a lot with usability. As an example, when using install.packages: > --- Please select a CRAN mirror for use in this session --- > CRAN mirror > > 1: 0-Cloud2: 0-Cloud > 3: Algeria4: Argentina (La Plata) > 5: Australia (Canberra) 6: Australia (Melbourne) > 7: Austria8: Austria > 9: Belgium 10: Brazil (BA) > 11: Brazil (PR) 12: Brazil (RJ) > 13: Brazil (SP 1) 14: Brazil (SP 2) In the listing above there are duplicate entries for 0-cloud and Austria pointing to http and https versions of the same mirror. __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

If you update to R-patched, you'll see the difference. With current
releases of R, you'll see some mirrors twice: the first one is https,
the second is http.
The other issue you may have is that your system may be configured to
default to a method that doesn't support https. Try
download.file("https://cran.rstudio.com";) and
readLines(url("https://cran.rstudio.com";)) to confirm that's not a
problem for you.

Oops, you need to give a destination. Try
download.file("https://cran.rstudio.com";, destfile = (f <- tempfile()))
