Error converting a ggplot2 polar plot to plotly

Hi all!

I am just starting with plotly. I usually work with R and in this case I would like to convert a simple polar plot made with ggplot2 to plotly. I have tried with a toy example, but I get an error message I cannot solve. I would appreciate very much any hint.

This is my R code example:

library(ggplot2)
library(plotly)
kk <- data.frame(x = c(45, 90, 90, 180, 290),
                 y = c(1, 2, 5, 3, 4),
                 z = as.factor(c(1, 1, 1, 2, 2))
                )
p <- ggplot(kk, aes(x = x, y = y, colour = z) ) +
  geom_point() +
  coord_polar(theta = "x", start = 0, direction = 1, clip = "on") +
  scale_x_continuous(limits = c(0, 360), 
                     breaks = (c(0, 90, 180, 270)))
p
p <- ggplotly(p)
p

With ggplot I obtain this plot:
Rplot

but after “ggplotly”, I get the following error:

> p <- ggplotly(p)
Warning messages:
1: In min(z$x.range %||% z$x_range) :
  ningún argumento finito para min; retornando Inf
2: In max(z$x.range %||% z$x_range) :
  ningun argumento finito para max; retornando -Inf
3: In min(z$y.range %||% z$y_range) :
  ningún argumento finito para min; retornando Inf
4: In max(z$y.range %||% z$y_range) :
  ningun argumento finito para max; retornando -Inf

and the following plot:

Any hint?

Thanks, Pedro

PS: of course, I have seen another way of making polar coordinate scatterplots with plotly, but I would like to do it with ggplot because it is easier ( and shorter) to obtain colors for the different levels of a factor, and others…

Unfortunately ggplotly does not yet support polar coordinate system. You can subscribe to this issue https://github.com/ropensci/plotly/issues/878 to keep up to date on any changes.

Thanks for your answer!!
