Labels are cut off on the right for some settings when saving a dendrogram

[christofs]

Hi everyone, I just noted a strange phenomenon and hope you have an idea what causes this:

If I create a dendrogram using stylo() – in version 0.7.4 – and keep everything the same except the MFW setting, this happens:

• At 100 MFW, the text labels are cut off on the right.
• At 1000 MFW, the text labels are not cut off.

This behavior does not make any sense, at least not to me.

Any hint is highly appreciated!

It looks like there's a much bigger range of distances for the first analysis than the second—and many more values that are very close to zero. This makes it tougher to handle long labels.

Dendrogram margins are hardcoded in stylo.R lines 1163-1169 as allowing the equivalent of 8 + 0.1 lines of text on the right hand side. Since these are defined internally and re-adopted each time a dendrogram is printed, it isn't possible for a user to adjust them for a single figure. One solution could be for stylo() to add an optional "nudge" argument, which should be easy to add, if it's desired.
