An strange error while use ggplotly

[Gerde]

Hi,

I came across an error while use ggplotly:
The code:

library(ggplot2)
library(plotly)

df <- data.frame(x = rep(c('A','B','C'),3), y = 1:9, group = rep(c('x','y','z'),each = 3))
p <- ggplot(df, aes(x = x, y = y, group = group)) + geom_line()

ggplotly(p)

errors:

This code runs ok for me...there is likely an issue with your Cairo device...does this run ok for you?

library(Cairo)
Cairo(600, 600, file="plot.png", type="png", bg="white")
plot(rnorm(4000),rnorm(4000),col="#ff000018",pch=19,cex=2) # semi-transparent red
dev.off()
