The USE flag in question causes misconception and people have no clue what it actually means. Its supposed to control whether you get a gui or not. Please change it to "gui" or "qt" as it uses the Qt toolkit. https://bugs.gentoo.org/712254 [ Legend : U - final flag setting for installation] [ : I - package is installed with flag ] [ Colors : set, unset ] * Found these USE flags for sci-mathematics/rstudio-1.3.1056: U I - + dedicated : Add support for dedicated game servers (some packages do not provide clients and servers at the same time) - - libressl : Use dev-libs/libressl instead of dev-libs/openssl when applicable (see also the ssl useflag) + + server : Build and install the RStudio server "game servers"? Let's go and play rstudio. :) Marking this a as "major" because if you get confused and you enable dedicated you wont get a major feature - R IDE.
