Adding custom text via layout option fails

[AliciaSchep]

I think adding an option to make it easy to add overlay text would be a nice addition to this package, so I'll leave this issue open...

You would need to pass the annotations as a list of list, e.g.

plot <- iheatmap(data = data, layout = list(annotations = list(list(text = "hi", x = 0.5, y = 0.5, xref = "x", yref = "y")))) 

Note that this kind of annotation will add a little arrow, which may not be what you want here... but can be addressed by adding showarrow = FALSE

Thank you, greatly appreciate the help!

Sorry to bug you again, but I have discovered a new issue related to this.

Under your suggestion, the annotation works well:
iheatmap(data = data, layout = list(annotations = list(list(text = "hi", x = 1, y = 1, xref = "x", yref = "y", showarrow = F)))) produces:

(please ignore the bar across the top, RStudio seemed to be glitching on image export)

However, when I try to do the same thing and add row labels, the annotation disappears:
iheatmap(data = data, layout = list(annotations = list(list(text = "hi", x = 1, y = 1, xref = "x", yref = "y", showarrow = F)))) %>% add_row_labels(ticktext = c("a", "b")) produces:

I was thinking that the row labels might be "overriding" the annotations, so I tried to add them on afterwards via "modify_layout", but the problem persisted.
iheatmap(data = data) %>% add_row_labels(ticktext = c("a", "b")) %>% modify_layout(list(annotations = list(list(text = "hi", x = 1, y = 1, xref = "x", yref = "y", showarrow = F)))) produced:

I assume this is actually a bug, or perhaps I'm simply extending the package beyond its intended use.

I would like to follow up on this issue.
