Could you add some new options? about ggtree

I agree with @dmneedha that using geom_text to do it manually is more flexible.

I have updated ggtree with a function, get_heatmap_column_position, which will output a data.frame that contains position information of where the column names should be placed. Then we can use geom_text to label the column name manually.

beast_file <- system.file("examples/MCC_FluA_H3.tree", package="ggtree")
beast_tree <- read.beast(beast_file)
p <- ggtree(beast_tree, mrsd="2013-01-01")
p2 <- gheatmap(p, genotype, offset = 2, width=0.5, colnames=F) 
df = get_heatmap_column_position(p2, by="bottom")
p2 + geom_text(data=df, aes(x, y, label=label), nudge_y=-1, angle=45)

Thanks for your suggestion.

I will consider to implement point 1.

For point 2, it's more complicated for I need to modify the source code of ggplot2::geom_tile.

For point 3, I don't think it's a good idea, since different color scheme for different column will make it hard to compare among columns.

Hi! Thanks a lot! Could you let me know when it will be done?

[dmneedha]

Thanks for making ggtree, it's great! I agree with the request for "Changing angle of labels above". In the interim is there a way to ggplot2 to rotate them manually? I'm new to ggplot2, unfortunately. Thanks!

Great! Thanks!
