Sys.setenv(LANGUAGE= "en")

R given installation package:

c:/Rtools/mingw_32/bin/g++: not found make: *** [ipcmutex.o] 
Error 127 
ERROR: compilation failed for package 'BiocParallel'

Google found what turned out to be a problem Rtools environment variables, re-installation settings a bit Rtools

#下载Rtools，网址
https://cran.r-project.org/bin/windows/Rtools/
#安装
#加入环境变量
#检查Rtools有无报错
system('g++ -v')
system('where make')

If error, it is necessary to manually set environment variables Rtools
