check lightMode for light background color
checkLightMode(lightMode = NULL, ...)logical or NULL, indicating whether the lightMode parameter has been defined in the function call.
logical or length=1, indicating whether lightMode is defined
Check the lightMode status through function parameter, options, or environment variable. If the function defines lightMode, it is used as-is. If lightMode is NULL, then options("jam.lightMode") is used if defined. Otherwise, it tries to detect whether the R session is running inside Rstudio using the environmental variable "RSTUDIO", and if so it assumes lightMode==TRUE.
To set a default lightMode, add options("jam.lightMode"=TRUE) to .Rprofile, or to the relevant R script.
