[ESS] lintr and flyspell

[Laurent Gatto]

I used it in the past and got a bit annoyed to the default settings. I
just gave it another try and a bit more time to learn how customise it;
see below.

The available linters are listed in README.md. To update the line
length, one would

'M-x customize-option' -> 'flycheck-lintr-linters' and set
  'with_defaults(line_length_linter(120))'

To get rid of the trailing blank lines info

'M-x customize-option' -> 'flycheck-lintr-linters' and set
  'with_defaults(trailing_blank_lines_linter=NULL)'

and, although not tested, both customisation would be set with

   with_defaults(trailing_blank_lines_linter=NULL, line_length_linter(120))

Note that I had to set flycheck-lintr-caching to nil (via M-x
customize-option) to get lintr to work.

This is with the latest lintr from github (currenlty version
0.3.0.9000), flycheck 0.24snapshot (package 20150409.1217 from melpa)
and emacs 24.4.2.

Best wishes,

Laurent
