FA list(...), I would like to zoom in to the leaves of
FA large trees in a dendrogram plot. The playwith package
FA allows zooming by passing xlim and ylim arguments to the
FA plot call (Hmisc does this too I think). But currently
FA stats:::plot.dendrogram does not accept xlim or ylim. So
FA I would like to enable that. In place of the existing
FA code chunk:
xlim - c(x1 - 1/2, x2 + 1/2)
ylim - c(0, yTop)
if (horiz) {
xl - xlim
xlim - rev(ylim)
ylim - xl
tmp - xaxt
xaxt - yaxt
yaxt - tmp
}
plot(0, xlim = xlim, ylim = ylim, ..
I propose something like:
function(..., xlim, ylim)
xlim0 - c(x1 - 1/2, x2 + 1/2)
ylim0 - c(0, yTop)
if (horiz) {
xl - xlim0
xlim0 - rev(ylim0)
ylim - xl
tmp - xaxt
xaxt - yaxt
yaxt - tmp
}
if (missing(xlim)) xlim - xlim0
if (missing(ylim)) ylim - ylim0
plot(0, xlim = xlim, ylim = ylim, ..
Thank you for the suggestion!
Yes, something like this will be part of R 2.8.0
(or 'R-devel' as from tomorrow).
