I would like to use some r-scripts from processing toolbox but I get this error massage:
The downloaded source packages are in â/tmp/RtmpdP9CQf/downloaded_packagesâ Warning message: In install.packages("rgdal", dependencies = TRUE) : installation of package ârgdalâ had non-zero exit status tryCatch(find.package("raster"), error=function(e) install.packages("raster", dependencies=TRUE))  "/usr/local/lib/R/site-library/raster" library("raster") Loading required package: sp library("rgdal") Error in library("rgdal") : there is no package called ârgdalâ Execution halted
I installed r-base and r-base-dev 3.4 from CRAN-repository. R is activated as provider in my QGIS 2.18.9 processing toolbox.
EDIT: I also tryed to install RGDAL via R and got a similar error:
