I've installed R (3.2.2) in latest lubuntu (apt-get) and the RStudio (0.99.489 - Ubuntu 12.04+ 32-bit).  R works from command line, but the IDE fails to launch from the shortcut that installation placed for some reason in the Graphics section.  Same with RStudio's shortcut in Programming.  When I try and run /usr/share/applications/R.desktop I get:me@system:~$ . /usr/share/applications/R.desktop [Desktop: command not foundsoftware: command not foundScience: command not foundMath: command not foundAnd..me@system:~$ . /usr/share/applications/rstudio.desktop [Desktop: command not foundbash: fg: %F: no such jobbash: text/x-r: No such file or directorybash: text/x-R: No such file or directorybash: text/x-r-doc: No such file or directorybash: text/x-r-sweave: No such file or directorybash: text/x-r-markdown: No such file or directorybash: text/x-r-html: No such file or directorybash: text/x-r-presentation: No such file or directorybash: application/x-r-data: No such file or directorybash: application/x-r-project: No such file or directorybash: text/x-r-history: No such file or directorybash: text/x-r-profile: No such file or directorybash: text/x-tex: No such file or directorybash: text/x-markdown: No such file or directorybash: text/html: No such file or directorybash: text/css: No such file or directorybash: text/javascript: No such file or directorybash: text/x-chdr: No such file or directorybash: text/x-csrc: No such file or directorybash: text/x-c++hdr: No such file or directorybash: text/x-c++src: No such file or directoryGrateful for advice how figure out what's going wrong here.Edit: as per request below.me@system:~$ lsb_release -aNo LSB modules are available.Distributor ID: UbuntuDescription:    Ubuntu 15.10Release:    15.10Codename:   wily
