ly_lines: Error in max(data_lengths) : invalid 'type' (list) of argument

[Atrebas]

Hi, Could you clarify the behaviour below? Maybe I missed something...

library(rbokeh)
library(data.table)

dat = data.table(x=1:3, 
                 y=c(1,1.5,1)+rep(0:3, each=3),
                 group=rep(LETTERS[1:4], each=3),
                 color=rep(c("blue","red"), each=3))

## #1. The three following lines work
figure() %>% ly_lines(x=x, y=y, data=dat)
figure() %>% ly_lines(x=x, y=y, data=dat, group=group)
figure() %>% ly_lines(x=x, y=y, data=dat, color=color) 

## #2. This one does not work
figure() %>% 
  ly_lines(x=x, y=y, data=dat, group=group, color=color)

## #3. Same parameters with ly_polygons works
figure() %>% 
  ly_polygons(xs=x, ys=y, data=dat, group = group, color=color) 

###
## data.table_1.9.7 rbokeh_0.4.2 

#2 gives the following error Error in max(data_lengths) : invalid 'type' (list) of argument In addition: Warning messages: 1: In max(idxs) : no non-missing arguments to max; returning -Inf 2: In max(idxs) : no non-missing arguments to max; returning -Inf 3: In max(idxs) : no non-missing arguments to max; returning -Inf 4: In max(idxs) : no non-missing arguments to max; returning -Inf

rbokeh is awesome! Thank you.

Confirming. Also no need to use a data.table; data.frame() produces the same effect.

Very sorry for the delay. This does indeed need to be fixed and I'm looking into it.

This is fixed but is hanging out in the dev branch until it is ready to go live. You can test it out with devtools::install_github("bokeh/rbokeh@dev").

Yes, it works. Thanks!
