More precisely: $RHOME/cmd/pager which in turn looks at $PAGER:

$ more cmd/pager 
pager=${PAGER-"more -s"}
if [ "$1" != "" ]
then exec $pager < $1
else exec $pager
# For the curious: "pager $1" doesn't work in batch, because "more" will
# eat the rest of stdin. The no-argument version is intended for use 
# at the end of a pipeline.

[If you want less -XE as default for R - e.g. to be able to scroll
back - you might add 

PAGER="less -XE" 

to the bin/R startup script]
