Help!

Hi Guangchuang,

I used your ggtree package with success a year or so ago but can't repeat what I did then, using the dat input material/data, after updating R/ggtree/everything, since.

I get the following error message when trying to draw the tree : Error in split.default(x = seq_len(nrow(x)), f = f, drop = drop, ...) : group length is 0 but data length > 0### Prerequisites

My approach (which worked last time) was as follows:

read in my "phylip/newick" type file.

tree <- read.tree("tk.ph.phy")

use 'ape' to write this into a format that ggtree understand better.

write.tree(tree, file = "eKin.nwk", append = TRUE, digits = 10, tree.names = TRUE)

create a tempfile to fill with out data and tree:

outfile <- tempfile()

specify path of our kinome tree file (which I have converted to nwk file format using 'ape')

eKin_tree <- paste("eKin.nwk")

create a jplace object using ggtree and then read it back in:

write.jplace(eKin_tree, data, outfile) eKin_jp <- read.jplace(outfile)

plot the tree in circular form:

ggtree(eKin_jp, layout = "circular")

Any help would be gratefully received.

Best Regards,

Dean
