R XML ERROR: 'configure' exists but is not executable centos 7 - r

Question

I've been having quite a time installing XML on a shiny server. It is currently installed, but I can't quite install it on a separate user, shiny or using sudo.

I've also installed the most recent version of libxml2-devel and libxml2
(using sudo yum install libxml2-devel and sudo yum install libxml2).

Answer 1

It's actually fairly straightforward. Using sudo R to start R, do the following:
dir.create("/home/username/tmp/")
Sys.setenv(TMPDIR="/home/username/tmp/")
install.packages(“XML”)
