During startup - Warning messages:
1: package 'utils' in options("defaultPackages") was not found
2: package 'stats' in options("defaultPackages") was not found
解决方案：
You're missing "which" I think.
In this code chunk system(paste(which, shQuote(names[i])), intern = TRUE, ignore.stderr = TRUE), which is an object from Sys.which and its value is the string "/usr/bin/which".
You should try installing which.
