This was really frustrating. I’m trying to modify a package from Matt Johnson and although I could get the package he sent me to install flawlessly, I couldn’t un-tar it, make a change, re-tar it, and then R CMD INSTALL it. I was about to pull out my hair. The error I got was:
ERROR: cannot extract package from ‘hrm-rev9.tar.gz’
The secret: you have to have the name correct.
R CMD INSTALL hrm-rev9.tar.gz
barfs. But
R CMD INSTALL hrm_0.1-9.tar.gz
works fine. I’m sure it’s somewhere in the docs. I just couldn’t find it.
As always, I made a script to do it for me: (Updated 6/17/2010 15:41)
#!/bin/bash
# Quick script to tar & gzip the package, remove the old one, and install the new one
# I'll add options automatically tag and release it later.
#Set the library that I'm using
LIB="/home/vanhoudn/R/i486-pc-linux-gnu-library/2.10/"
#Commit
svn commit -m "Build commit"
#get the revision number from svn
REV=`svn info -R | grep Revision | cut -d: -f 2 | sort -g -r | head -n 1 | sed 's/ //g'`
#Build the filename
FILENAME="hrm_0.1-$REV.tar.gz"
# I need to tar up the pkg so I can install it.
# Jump to the parent directory and work from there.
cd ..
# Exclude any hidden files under the directories (svn has a bunch)
# and add the named files
tar czf $FILENAME --exclude '.*' hrm/DESCRIPTION hrm/NAMESPACE hrm/src hrm/R
# Remove the old version of the package
R CMD REMOVE -l $LIB hrm
# Install the new package
R CMD INSTALL $FILENAME
# Clean up
rm $FILENAME
# Go back to our previous directory
cd hrm
