[R] Plots Without Displaying

> Yes, you can do that for lattice-based plots.  The functions in the lattice

> processed or updated at a later time:

Or for ggplot based plots:

install.packages("ggplot")
library(ggplot)

> plotList <- list(length=3)
> plotList[[1]] <- qplot(yield, site, data=barley)
> plotList[[2]] <- qplot(yield, variety, data=barley)
> plotList[[3]] <- qplot(yield, year, data=barley)

Which actually stores plot objects which are independent of their
representation as graphics.
