try ?plot.default
which states:
frame.plot: a logical indicating whether a box should be drawn around
the plot.So the following:
postscript(file = "hc605.ps")
plot(as.dendrogram(reshc), horiz = TRUE, ylab = "", main = " ",
frame.plot = FALSE)
dev.off()should get you what you want.
plot.dendrogram doesn't explicitly mention frame.plot, but the ... allows you to pass plotting parameters to other methods:
..., xlab, ylab: graphical parameters, or arguments for other methods.
As for the postscript -> gif - I'm not qualified to explain this, except that it must have something to do with the fact that by doing box(col="white") you aren't actually *deleting* the box, you are just overplotting on it.

Hi all,
I would like to save the dendrogram of a hierarchical clustering. Let reshc the result of the fucntion hclust(). To save the dendrogram, I can use the function postscript:
postscript(file="hc605.ps") plot(as.dendrogram(reshc),horiz=T,ylab="",main=" ") dev.off()
Using the functions plot and as.dendrogram, it is possible to obtain an horizontal tree with option horiz=T.
The problem is there is a box around the tree...this box looks like the result of the function box() and it is possible
to delete it with box(col="white"). But when I convert the postscript file in gif or tiff file, this box is not deleted.
Could you explain me why this box appear after the conversion of my postscript file and a solution
to delete this box in a gif or tiff format? (I know I can use plot(reshc) but the tree is vertical in this case)
Regards, Olivier.
