Apologies for the noob question. I need to split setting up a plot
and drawing
it into two functions. One determines the properties of a plot
(data, axis,
labels, etc.), and the other plots it (using a preferred device, image
dimensions, etc.).
get.props = function() {
list(x=x, y=y, xlab="foo", ylab="bar")
}
myplot = function() {
props = get.props()
plot(props) # Doesn't work
}
What's the right way to call plot() with all the components of
props broken out
as separate parameters to plot()? Note that the components of props
may be
different from call to call (sometimes there's only x data,
sometimes there's no
ylab, etc.).
Thanks in advance for your time and help.
do.call(plot,props)
See ?do.call .
cheers,
