ggplot2 and equity timeseries plot.

I have tried using ggplot2 and I cannot seem to obtain an adequate finance timeseries.

What I need is the standard plot of, say S&P500 over say a two week period, which would contain 10 datapoints. But ggplot2 is including the weekends on the plot whereas I want to have the weekdays only plotted and still retain dates as the x-axis labels.

There are a multitude of examples in the various manuals and R-blog's for non-finance style graphs, but none comment on the usual need to exclude days on which the exchanges are closed.

Has anyone an example of a plot that does this?

Thanks

for now.

chartSeries (and chart_Series) in quantmod do this.  For example:

require(quantmod)
getSymbols("SPY")
chartSeries(SPY, subset="last 2 weeks")

Hope that helps,
