Configure the behaviour of R linters in Sublime 3 - json

Question

I am using lintr in Sublime 3 via SublimeLinter 3 and the SublimeLinter-contrib-lintr plugin. On the lintr README.md file there is a short mention on how to configure what linters should be used:
{
"user": {
"linters": {
"r": {
"linters": "with_defaults(line_length_linter(120))"
}
}
}
}
However, I am using it in conjunction with SublimeLinter-contrib-lintr and I can't get it to work. My SublimeLinter.sublime-settings file looks like this:
{
"user": {
"debug": true,
"delay": 0.25,
"error_color": "D02000",
"gutter_theme": "Packages/SublimeLinter/gutter-themes/Default/Default.gutter-theme",
"gutter_theme_excludes": [],
"lint_mode": "background",
"linters": {
"lintr": {
"#disable": false,
"args": [],
"cache": "TRUE",
"excludes": [],
"linters": "default_linters"
}
},
"mark_style": "outline",
"no_column_highlights_line": false,
"passive_warnings": false,
"paths": {
"linux": [],
"osx": [],
"windows": [
"C:/Program Files/R/R-3.3.3/bin/x64"
]
},
"python_paths": {
"linux": [],
"osx": [],
"windows": []
},
"rc_search_limit": 3,
"shell_timeout": 10,
"show_errors_on_save": false,
"show_marks_in_minimap": true,
"syntax_map": {
"r extended": "r"
},
"warning_color": "DDB700",
"wrap_find": true
}
}
The lintr package has a bunch of linters (see this link). What I would live to achieve is to discard some of them (i.e., not use, for instance, assignment_linter). Do you have any idea how to achieve this? It should be possible, right?
Edit 1:
I noticed that by changing "linters": "default_linters" to "linters": "assignment_linter", only the errors falling under assignment_linter will be picked. I tried to expand it using an array, but it doesn't work:
...
"lintr": {
"#disable": false,
"args": [],
"cache": "TRUE",
"excludes": [],
"linters": [
"assignment_linter",
"object_name_linter"
]
}
...
Inside the Sublime 3 console, the message error message with this attempt is: Error: unexpected '[' in "lint(cache = TRUE, commandArgs(TRUE), [".
Edit 2: possible solution
Looking at with_defaults inside the lintr package I found two ways of choosing only the linters I am interested in. Assuming that I only want assignment_linter and no_tab_linter, the configuration is:
"linters": "default_linters[c('assignment_linter', 'no_tab_linter')]" or
"linters": "with_defaults(assignment_linter, no_tab_linter, default = NULL)"
It works, but are there other less error-prone approaches? With this approach if I want to discard just one linter I have to list all the others.

Answer 1

Regarding your question for "Edit 2", you can discard a single linter as follows:
{
"user": {
"linters": {
"r": {
"linters": "with_defaults(some_default_linter = NULL)"
}
}
}
}
... where some_default_linter is the name of a linter from the list lintr::default_linters.
