Hi Thomas,

You may want to check out the quantmod package.  There is a whole
suite of charting functionality now included.

You will need to change the 'Last' colname to Close, but other than
that your data should work.  If you download the most recent build or
svn snapshot from http://r-forge.r-project.org/projects/quantmod
you'll find many additional functional that may be of use.

Additionally, there are some (possibly dated) examples on the main
site page at http://www.quantmod.com

The most recent version allows for custom tick mark location by dates,
as well as zooming capabilities.  Additionally TA analysis can be
applied to the charts (the underlying functionality coming from the
TTR package on CRAN and r-forge)

Jeff
