[R-SIG-Finance] Save a plot

[Brian G. Peterson]

The problem is that you need to open the png device, call your plots,
and then close the device.  You would do the same e.g. with a pdf.

Try something like this:

##########

library(PerformanceAnalytics)
library(quantmod)
library(png)


png("plot-1.png", width=1000, height=600)
chart.CumReturns(ret,wealth.index = TRUE,legend.loc = "bottomleft",
yaxis.pct=100)
title("SP500 reval", adj = 0, line = 3, cex.main=1.25)
title("Eco", adj = 0.75, line = -22)

dev.off()
##########

I also wonder about the multiple calls to title().  chart.CumReturns has a title argument.
