I'm trying to run parallel computing. Hence I install package Rmpi.
install.packages("Rmpi")
require("Rmpi")
Could you please elaborate why there is such error message while I've just installed the package?

I added the following and then rJava loaded without error.
Sys.setenv(JAVA_HOME='C:\\Program Files\\Java\\jre1.8.0_221')
I'm new with R unfortunately, but i need it to open a specific file which should be a graphical user interface.
After the source command:
source("D:\\R\\win-library\\3.5\\muxViz-master\\muxVizGUI.R")
I'm facing this error:

Please help.
The last line of muxVizGUI.R is runApp(getwd()). It expects that your working directory is the same directory in which the ui.R and server.R files are located. You should change to that directory before sourcing the file:
setwd("D:\\R\\win-library\\3.5\\muxViz-master")
