Patched xBalance.make.stratwts.R to pass through stratum weights directly. Still having some problems elsewhere.
Small change to plot.xbal to allow for different stats to be plotted
Equipping xBalance to gracefully handle weird strata input (nlevels=0)

xBalance crashed a script I was running because it had been fed a
strata= argument one of the elements of which was a factor with no
levels.  (It had only NAs.)  In my situation as in any others like this
I could imagine, I'd have been happier to have it proceed with the
non-nonsensical strata.  So I've added exception-handling code to make
it do this. There is an accompanying addition to the tests file.
Makefile for package tasks
more Makefile goodness
fix for autotesting code
porting some Makefile improvements from optmatch, safer Rprofile use
setting up testthat based tests in inst/tests (as recommended by devtools wiki)
bringing over some tools from optmatch: roxygen, more Makefile, spell checking
Adding test output introduced in 169e6b0800
cleaning up discrepancies caused by versions of SparseM, xtable, R
fixed bug in loading local RItools
Explicitly fetching storing check dependencies
convenience task to print out current package name (e.g. RItools-0.9_7.tar.gz)
Fixing x86_64 linux/R 2.15.2 `R CMD check` bug

While it is not clear as to the reason, on Arch Linux x86_64 using R
2.15.2, the following would fail to find libraries installed in .local:

  R_LIBS=.local R --vanilla CMD check RItools.tar.gz

The R 2.15.2 release notes have some stuff about trying load packages
during the check process that are not on the usual library paths, which
may be related. Luckly add the `-l .local` flag to the check process
seesm to clear up the issue.
quieting 'make check' warnings, all superficial
ignoring build products on case sensitive file systems
splitting up clean task: local files vs. deps
If the base svd function fails, use the one from propack (the svd package).
Added a dependency on the svd package.
