RStudio 0.9x 데스크탑 아이콘을 lubuntu 15.10에서 열 수 없습니다

apt-get최신 lubuntu() 및 RStudio(0.99.489 - Ubuntu 12.04+ 32비트)에 R(3.2.2)을 설치했습니다. R은 명령줄에서 실행되지만 Graphics어떤 이유로 설치 시 이 섹션에 배치된 바로 가기에서 IDE를 시작할 수 없습니다. RStudio의 단축키와 동일합니다 Programming. /usr/share/applications/R.desktop을 실행하려고 하면 다음과 같은 결과가 나타납니다.

me@system:~$ . /usr/share/applications/R.desktop
