After searching multiple combinations of keywords over the past two
days and downloading n R graphics tutorials, I have not been able to
find anything online or in my R books about how to save multiple plot
panes to PNG.
Specifically, I am using the irf() function in the vars package to
generate plots of Impulse Response Functions:
> x.data <- cbind(na.omit(returns(p[,2])),na.omit(returns(n[,2])))
> colnames(x.data) <- c("p.ret","n.ret")
> x.jo <-
ca.jo(x.data,type="trace",ecdet="none",spec="transitory")
> x.var <- vec2var(x.jo)
> x.irf <- irf(x.var,n.ahead=30)
> plot(x.irf)
This results in a plot containing a pair of IRF graphs in Quartz and
the following message in the Console:
"Hit <Return> to see next plot:"
When one hits <Return>, the next pair of IRF graphs appears in Quartz.
When I try to save the plots to PNG
> png(...)
> plot(...)
> dev.off()
I am able to save only one of the plots. How does one tell plot() to
plot first one of the panes and then the second?
Any help would be greatly appreciated.
Yours,
Charles Evans
Do you want the stuff to appear on one page? Have you tried opening a device with multiple plots? For example via: par(mfrow=c(2,2)) or: layout(matrix(1:4,2,2)) Other than that the documentation for the "vars" package gives you details for a plot function that may be used for plotting your irf objects. There is an argument (plot.type) that can be set to plot multiple plots on one page. ??

I cannot run your example because I cannot identify which package the function returns is from. Nonetheless, something like par(mfrow=c(2,3)) should do the trick.

Thank you everyone who contacted me so quickly! I am posting the solution here, so that it is in the archive: > plot(x.irf , plot.type="multiple" , names="p.ret") > plot(x.irf , plot.type="multiple" , names="n.ret") The returns() function in is the timeSeries package. However, one can replace the "na.omit(returns(x[,2]))" bits below with any two vectors of data.
