Hello,
In trying to minimize the margin on the left hand side when using
dotchart I found what may be a typo in the code.
In the lines below from dotchart.R, should nmai[4L] be nmai[2L]?
if (!(is.null(labels) && is.null(glabels))) {
nmai <- par("mai")
nmai[2L] <- nmai[4L] + max(linch + goffset, ginch) + 0.1
par(mai = nmai)
}
I think not. It is unclear what the intention is, but it seems to be to visually balance the left and right margins of the whole plot including the labels. It goes back a very long way: the changes since dotchart replaced dotplot in 2001 are merely cosmetic.
