Add annotation to the heatmap

[harimchun]

Hi, I am trying to add annotation information to the heatmap.

I have GO terms that are observed from a specific condition and want to visualize specific terms are observed from which condition.

I tried to add annotation information to the heatmap using the R code below by concatenating additional code
ht_clusters(mat, cl, term = NULL) %v% HeatmapAnnotation(colAnn, which='column')
However, it doesn't work.

How can I add annotation information to the heatmap?
