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
