R help - Nov 2010 - plot.dendrogram() plot margins

Hello,

Is it possible to remove those extra margins on the "sample" axis from
plot.dendrogram:

par(oma=c(0,0,0,0),mar=c(0,0,0,0))
ddr<-as.dendrogram(hclust(dist(matrix(sample(1:1000,200),nrow=100))))
stats:::plot.dendrogram(ddr,horiz=F,axes=F,yaxs="i",leaflab="none")

vs.

stats:::plot.dendrogram(ddr,horiz=T,axes=F,yaxs="i",leaflab="none")

What variable / line of code corresponds to this additional margin space? I
would like to modify the code to remove the extra space and have that margin
equal to that when horiz=T, for plotting multiple dendrograms for one images
on the same device.

Thanks in advance, best.

I guess you want

  par(xaxs="i")
 
stats:::plot.dendrogram(ddr,horiz=F,axes=F,yaxs="i",leaflab="none")
