parser was built in core R from version 3.0.0 and it has really great features that I use e.g. in my sandboxR package, which also has to check bunch of stuff about user provided R code. Quick demo:

> getParseData(parse(text = 'library(RColorBrewer)'))
  line1 col1 line2 col2 id parent                token terminal         text
9     1    1     1   21  9      0                 expr    FALSE

Yep I am using the built in parser functions extensively in lintr, this
issue was just a place for me to keep links to pre-existing linting tools
