After following the R installation guide and trying everything I could find suggested here, I still cannot get R to initialize from KNIME on a new Mac.
KNIME R Scripting extension is installed: |4.0.0.v202009100739|de.mpicbg.tds.knime.scripting.r.feature.feature.group|Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG), Dresden, Germany|
clang and GNU Fortran are freshly installed.
xQuartz: XQuartz 2.8.0_rc4 (xorg-server 1.19.7)
Rserve and Cairo are installed
R version 4.0.4 (2021-02-15)
Platform: x86_64-apple-darwin17.0 (64-bit)
Running under: macOS Catalina 10.15.6
Matrix products: default
attached base packages:
 stats graphics grDevices utils datasets methods base
other attached packages:
 Rserve_1.8-7 Cairo_1.5-12.2
loaded via a namespace (and not attached):
 compiler_4.0.4 tools_4.0.4
Rserve is running, Applications indexing is enabled (per a suggestion from a related query)
The path to R is correctly specified in the KNIME preferences, but the “R scripting” menu I expect from successful R-KNIME integrations on other Macs (different OS and KNIME versions) is missing here. Is this diagnostic?
Any ideas for what I am missing/doing wrong?
