[R] rcdk설치시 오류 해결방법

환경은 다음과 같습니다.

 

version : Ubuntu 20.04 1LTS

R version : 4.0.3

 

rcdk를 이용하기 위해서 설치를 하니 다음과 같은 오류가 떳습니다.

 

configure: error: One or more Java configuration variables are not set.
Make sure R is configured with full Java support (including JDK). Run
R CMD javareconf
as root to add Java support to R.

If you don't have root privileges, run
R CMD javareconf -e
to set all Java-related variables and then install rJava.

terminal 에서 다음과 같이 했지만 해결되지가 않았습니다.

terminal에서 바로 깔아 보려했지만 다음과 같이 오류가 떳습니다.

 

user@usercom:~$ sudo apt install r-cran-rjava

포기하려다가 구글교수님에게 찾아보니 다음과 같은 이야기를 하십니다.

 

sudo add-apt-repository ppa:c2d4u.team/c2d4u4.0+
sudo apt-get update
sudo apt install r-cran-rjava

 

위와 같이 진행하게되면 rjava가 설치가 되어야 합니다.. 그리고 rcdk를 설치를 해보니..

 

rcdklibs를 설치하라고 해서 그것도 설치하고 다시 rcdk 설치를 하니!! 되네요

 

굳굳 rcdk를 이용하여 tanimoto coefficient분석을 할 생각입니다.!
