Thank you Greg!
Well, your solution certainly is sub-optimal, since the ?axp parameters
really give coordinates of outermost axis labels, instead of the plotting
region, and "fin" is the figure's not the plot's region;
i.e. rather, you'd use
par.uin <- function()
par("pin") / {u <- par("usr"); c(diff(u[1:2]),
diff(u[3:4]))}
BTW: "uin" gives ``inches per usr unit'' (not the reverse as
you suggest).
Should `R' provide "uin" (as read-only) par() ?
