Hi,

I am trying to install and run some R programs on V7R4.  I am having difficulties with the following.  Any ideas?

> install.packages("DescTools")
Warning message:
package 'DescTools' is not available (for R version 3.6.3)

> install.packages("rcompanion")
Warning message:
package 'rcompanion' is not available (for R version 3.6.3)

Also 

install.packages("car") fails - cannot find libintl.h and then tries cmake but cannot find that either. cmake is installed using ACS version 3.16.9-1 (the latest).

> install.packages("car")
gcc -I"/QOpenSys/pkgs/lib/R/include" -DNDEBUG -DNTIMER -I./SuiteSparse_config -DUSE_FC_LEN_T  -pthread -mminimal-toc  -fPIC  -O2 -g -maix64 -mtune=power6 -mcpu=power6  -c CHMfactor.c -o CHMfactor.o

Alternatively install CMake from: <https://cmake.org/>

Thanks for any help.
