I had an error when I tried to update rgdal. It said that gdal 2.1.4 was installed whereas brew installed version 3.1 The 2.1.4 version was installed previously manually in : /Library/Frameworks I remove the gdal folder, installed gdal using brew and all is ok now: brew install gdal and in R: install.packages("rgdal") Note that rgdal should be replaced by terra in future

echo $USER will show your login name; for example myname Then do: sudo chmod -R 777 /Users/myname/Library/R/4.0/library/ and you will be able to install packages within RStudio

In terminal: sudo apt-get update -y sudo apt-get install -y fftw3 In R install.packages("imager") More infos here: http://dahtah.github.io/imager/ In MacOSX:  brew install imagemagick ffmpeg Note: imagemagick@6 is keg-only, which means it was not symlinked into /usr/local, because this is an alternate version of another formula. If you need to have imagemagick@6 first in your PATH, run:   echo 'export PATH="/usr/local/opt/imagemagick@6/bin:$PATH"' >> ~/.zshrc For compilers to find imagemagick@6 you may need to set:   export LDFLAGS="-L/usr/local/opt/imagemagick@6/lib"   export CPPFLAGS="-I/usr/local/opt/imagemagick@6/include" For pkg-config to find imagemagick@6 you may need to set:   export PKG_CONFIG_PATH="/usr/local/opt/imagemagick@6/lib/pkgconfig"

Sometimes it is not possible to use only ASCII character and it prevents to pass the CRAN check. For example, if you need to use "−"; clearly it will generate an error in the CRAN check. The solution is to use the chr() and asc() functions of my HelpersMG package available in CRAN: Do: > asc("−") [1] 195 162 203 134 226 128 153 And replace "−" in your code by: > chr(c(195, 162, 203, 134, 226, 128, 153)) [1] "−" You will have the magic message: Status: OK after your check for CRAN! https://cran.r-project.org/web/packages/HelpersMG/index.html
