DENDRO | Genetic Heterogeneity Profiling by Single Cell RNA | Genomics library

As a workaround you could follow this tutorial by Dave Tang:

Change keepSamples = (Cutreecluster_Sample==!0) to keepSamples = (Cutreecluster_Sample!=0)

Why? Evaluating your command from right to left: !0 is a logical negation of 0, which is equivalent to !FALSE in R. Thus !0 is equal to TRUE. You then check if Cutreecluster_Sample equals TRUE. TRUE coerced to numeric is 1 in R. Thus your check is actually TRUE iff samples are in cluster 1, not cluster 0.

Try !0 == 1 and FALSE == 0.

The problem is not with your resolution, but the size of the image (or the size of the lines). Since i do not know how to change the linewidth in the dendogram plot, i will just go with the straight forward solution to make a HUGE image.

As mentioned in my comment, you can do this quite easily by ggplot2 facetting. Here's a rough example.

Seems you were confusing dendrogram with dendrogram data. This will work:

I have figured it out upon reading one of the examples in R. Here is what one has to do using the similarity matrix.

From the documentation:

Components have a well-defined lifecycle Each component can implement "lifecycle hooks". These are methods that will be called at certain points in the life of the component. The following hook methods can be implemented:

• $onInit() - Called on each controller after all the controllers on an element have been constructed and had their bindings initialized (and before the pre & post linking functions for the directives on this element). This is a good place to put initialization code for your controller.
• $onChanges(changesObj) - Called whenever one-way bindings are updated. The changesObj is a hash whose keys are the names of the bound properties that have changed, and the values are an object of the form

So you can just use:

Try this:
