What is the gitignore equivalent of "one or more occurrence"?

While working with R, Rstudio creates all these files:

.Rhistory
.Rapp.history
.Rproj.user/

I want git to ignore these files so I put them in .gitignore, and to do it in one line I use

*.R*

but it will also ignore actual .R files which I don't want. So I tried the below regexes,

*.R.+

and

*.R+

but I guess there is some other equivalent for dot (. for single character match) or plus (+ for one or more occurrences of previous letter) in gitignore which I am unaware of. Can anyone help?

Here you need to use ? . ? in glob matches any single character.

*.R?*

Reference

*

Matches any string, including the null string. When the globstar shell option is enabled, and ‘’ is used in a filename expansion context, two adjacent ‘’s used as a single pattern will match all files and zero or more directories and subdirectories. If followed by a ‘/’, two adjacent ‘*’s will match only directories and subdirectories.

?

Matches any single character.
