Re: [R-SIG-Mac] OpenJPEG in GDAL [Was: Problems with R and Big Sur]
Gilberto, well, that one is easy and has nothing to do with tools nor with BigSur - no one asked for OpenJPEG support so that's why OpenJPEG is not included on the build machine. There are several dozen of optional features in GDAL and I have no idea which are useful, which are not and which are legacy, so it's up to the rgdal maintainers or users to signal if there is anything useful missing. Given the complexity of GDAL dependencies and corresponding continuous build issues I'm relying on them to tell me when it's safe to update/change settings. Simply adding the OpenJPEG library seems sufficient: > grep("JP2", rgdal::gdalDrivers()$name, value=TRUE) [1] "JP2OpenJPEG" so that is now available in the CRAN binary.

Re: [R-SIG-Mac] INSTALL R 4.0.2
Dear Giuseppe, When asking for help, it is always a good idea to provide enough information to allow people to help you. I read you've downloaded the packages, but unclear what is: "thank opened". Further, what is "Basics / Prob calculator"?, and to what "layout" are you referring to, and from which "data"? There are 16000+ packages on CRAN, and it is therefore unreasonable to expect anyone to be familiar with all functions and datasets from all packages. A valuable netiquette rule says you should provide a so-called MRE - minimal reproducible example. More often than not, compiling such an example will reveal the solution to a problem even before posting (to thousands of subscribers) for help. I hope this helps, Adrian On Thu, Dec 3, 2020 at 2:55 PM Giuseppe Sant wrote: > That’s the right way to motivate me.

Re: [R-SIG-Mac] Problems with R and Big Sur
I can confirm the warning message on a 2020 macbook-pro-13-inch with Big Sur. I do not know about slowdowns, because I seldom work in R.app, and when I do, it’s just for a few moments at a time. I do not see the warning when I run R in a terminal, in vim, or in RStudio, which makes sense because the warning seems to be related to the GUI that R.app is employing. > On Dec 3, 2020, at 7:00 AM, Maria-Angeles Casares-de-Cal via R-SIG-Mac > wrote: > > CAUTION: The Sender of this email is not from within Dalhousie. > > Thank you very much for the interest shown by everyone who has sent their > answers. > > I think I have not explained well the issue.

Re: [R-SIG-Mac] Problems with R and Big Sur
Thank you very much for the interest shown by everyone who has sent their answers. I think I have not explained well the issue. Now, there it goes (I hope better explained!): I have a 16-inch MacBook Pro (2019), I have installed the Big Sur 11.0.1 operating system, I have installed the R 4.0.3 and the R GUI 1.73. The R works fine, I think it is a problem with the R GUI. When I open a session in R, I get the following warning: 2020-12-03 11: 34: 43.708 R [2479: 145386] Warning: Expected min height of view: () to be less than or equal to 30 but got a height of 32.00. This error will be logged once per view in violation. And from that moment, the management of the windows in R and the computer slows down. Also, every time I open a new file in R (in the same session), the warning appears again. One of the messages I received on this mailing list said that it could be a problem related to the TouchBar of the MacBook Pro. I have tested the same R and R GUI on a MacBook Air (Retina, 13-inch, 2020) with Big Sur, and, indeed, that problem does not appear. I know that in Terminal and RStudio there is no problem, but I would like to solve this issue, since I prefer to work with R and the R GUI in a Mac, instead of Terminal or RStudio. Thank you very much for your attention.
