Hi, I'm using the latticeExtra package's dendrogramGrob function to create a grob with both a dendrogram and a covariate bar (via the 'add' parameter). When the dendrogram has very short branches at its leaves, it appears as a line and becomes impossible to see when placed next to the covariate bar. For example: > x <- outer(-5:5, -5:5, &...

Dear all, I am using the heatmap representations of latticeExtra package and I would be interested to draw color side bars representing the groups of a factor of interest. From my understanding of : > help(dendrogramGrob) ... The 'add' argument can be used for additional annotation at the base of the dendrogram. It should be a list with one component for each row, with names specifying the type of annotation and components specifying the contents. Currently, the only supported nam...

Thanks, Alex
