The Art of R Programming

Well, that seemed to work, in the sense that R did install the package,

but R also noted that it had a problem with the threads library on our

machines. Sure enough, when I tried to loadRmpi, I got a runtime error,

saying that a certain threads function wasn’t there.

I knew that our threads library was fine, so I went into theconfigurefile

and commented out two lines:

# if test $ac_cv_lib_pthread_main = yes; then

MPI_LIBS="$MPI_LIBS -lpthread"

#fi

In other words, I forced it to use what I knew (or was fairly sure) would

work. I then reranR CMD INSTALL, and the package loaded without any

problems.

B.4 Listing the Functions in a Package............................................

You can get a list of functions in a package by callinglibrary()with thehelp

argument. For instance, for help on themvtnormpackage, type one of the

following:

• 
  

  
  

  library(help=mvtnorm)

  
  

  
  


• 
  

  
  

  help(package=mvtnorm)
