Linting Google Style variable and function naming

[xiamaz]

I have just started looking into R linting and am unsure, whether I am configuring the plugins correctly. I am coding based on the Google R Style guide, which recommends using lowerCamelCase or dot.naming for variables and UpperCamelCase for function names. As far as I have read in the documentation it seems to be possible to enforce either lowerCamelCase or snake_case, but I could not find settings to allow UpperCamelCase for functions.

Is it possible to configure it for this usecase? I would like to keep name linting to spot mistakes in my naming easier.

Hi @xiamaz, Based on the code, it looks like the available cases for object name linting are: https://github.com/jimhester/lintr/blob/e926089a0187aac01ce6981a798c5dc22e3a4273/R/object_name_linters.R#L151-L158

(The docs just give lowerCamelCase and snake_case as examples.)

Thanks for the answer @batpigandme. I did not know of the other options. This way I can keep rough linting of variables on! Is it possible to somehow only use UpperCamelCase for function assignments? What I would like to achieve is to only allow UpperCamelCase for function names and only lowerCamelCase and dotted.case for all other use cases.

I'm sure it's possible. You could probably adapt the logic/regex from the function/parentheses spacing linter and then apply names conditionally… https://github.com/jimhester/lintr/blob/e926089a0187aac01ce6981a798c5dc22e3a4273/R/function_left_parentheses.R#L17-L18
