For those of you who publish in scientific journals, how do you generally attribute R and/or RStudio? For example, with other software, in a Methods section I'll generally state something to the effect of:
"The decision analysis was performed using TreeAge Pro (TreeAge, Williamstown, MA)"
but haven't yet had to do this with R and RStudio. Do you generally cite both R and RStudio, or is citing just one of them sufficient?
