unable to load shared object R_X11.so

[ShixiangWang]

Anaconda use MRO as default R repository now, after I install R using Conda and open R, always get warning.

Warning message:
In doTryCatch(return(expr), name, parentenv, handler) :
  unable to load shared object '/public/home/liuxs/anaconda3/lib/R/modules//R_X11.so':
  /public/home/liuxs/anaconda3/lib/R/modules//../.././libharfbuzz.so.0: undefined symbol: g_unichar_decompose
R version 3.4.3 (2017-11-30) -- "Kite-Eating Tree"
Platform: x86_64-pc-linux-gnu (64-bit)

https://github.com/RevolutionAnalytics/RRO/issues/312 says

After download and install XQuartz from its website (https://www.xquartz.org), this warning message disappeared.

But I dont how to install this on CentOS 6 and I have no root permission.

This warning stops me from running conda R inside Jupyter. Getting a dead kernel. Urgently needs this problem fixed.

I'm having this problem after installation on Debian 9, but with: In doTryCatch(return(expr), name, parentenv, handler) : unable to load shared object '/opt/microsoft/ropen/3.4.4/lib64/R/modules//R_X11.so': libpng12.so.0: cannot open shared object file: No such file or directory

Looking deeper, the problem was this one here and my solution was the same - symlinked the libpng16.so to the libpng12 one.

I encounter the same issue in my JupyterLab, I couldn't run the R codes in notebooks.

The error: could not load anaconda3/lib/R/modules//R_X11.so could not load library /usr/lib/libXt.so.6

I have solved this issue on Centos 7 by installing the: sudo yum install libXt
