RStudio
lintr lints are automatically displayed in the RStudio Markers pane
(RStudio versions > v0.99.206).
RStudio Example
In order to show the “Markers” pane in RStudio: Menu “Tools” ->
“Global Options…”, a window with title “Options” will pop up. In that
window: click “Code” on the left; click “Diagnostics” tab; check “Show
diagnostics for R”.
To lint a source file test.R type in the Console
lintr::lint("test.R") and look at the result in the
“Markers” pane.
This package also includes two addins for linting the current source
and package. To bind the addin to a keyboard shortcut navigate to Tools
> addins > Browse Addins > Keyboard Shortcuts. It’s recommended
to use Alt+Shift+L for linting the current source lint and
Ctrl+Shift+Alt+L to code the package. These are easy to remember as you
are Alt+Shift+L(int) ;)
Emacs
lintr has built-in
integration with flycheck versions
greater than 0.23. 
Installation
lintr is fully integrated into flycheck when using ESS. See the installation
documentation for those packages for more information.
Configuration
You can also configure what linters are used. e.g. using a different
line length cutoff. - M-x customize-option ->
flycheck-lintr-linters ->
linters_with_defaults(line_length_linter(120))
Vim - syntastic
lintr can be integrated with syntastic for
on-the-fly linting.
Vim Example
Installation
Put the file syntastic/lintr.vim
in syntastic/syntax_checkers/r. If you are using pathogen this directory
is ~/.vim/bundles/syntastic/syntax_checkers/r.
You will also need to add the following lines to your
.vimrc.
let g:syntastic_enable_r_lintr_checker = 1
let g:syntastic_r_checkers = ['lintr']
Configuration
You can also configure what linters are used. e.g. using a different
line length cutoff.
let g:syntastic_r_lintr_linters = "linters_with_defaults(line_length_linter(120))"
Vim - ALE
lintr can be integrated with ALE for on the fly
linting.
Installation
lintr is integrated with ALE and requires no additional
installation.
Configuration
You can configure what linters are used, e.g. using a different line
length cutoff.
let g:ale_r_lintr_options = "linters_with_defaults(line_length_linter(120))"
You can also configure whether lint or
lint_package is used. Set to 1 for
lint_package and 0 (default) for lint.
let g:ale_r_lintr_lint_package = 1
See :h ale_r_lintr for more information.
Note that configuration through .lintr files are not
supported.
There is a work around that can be used to read the contents of a
.lintr file in the root of the working directory. This
would allow the use of configuration through .lintr
files.
if filereadable(".lintr")
let g:ale_r_lintr_options = join(readfile('.lintr'))
endif
Sublime Text 3
lintr can be integrated with Sublime Linter
for on-the-fly linting.
Sublime Example
Configuration
You can also configure what linters are used. e.g. disabling the
assignment linter and using a different line length cutoff. In the
SublimeLinter User Settings
{
"linters": {
"lintr": {
"linters": "linters_with_defaults(assignment_linter = NULL, line_length_linter(120))"
}
}
}
