Using frame parameter to making a plot from ggplot to plotly

Question

Here is my data:

data <- data.table(year = rep(1980:1985,each = 5),
                   Relationship = rep(c(" Acquaintance","Unknown","Wife","Stranger","Girlfriend","Friend"),  5),
                   N = sample(1:100, 30)
                   )

I can use plotly::plot_ly function to plot a Dynamic map of the years like this:

plot_ly(data
        ,x=~Relationship
        ,y=~N
        ,frame=~year
        ,type = 'bar'
)

but when I using ggplot with parameter frame ,I get a error Error in -data$group : invalid argument to unary operator

here is my ggplot code :

p <- ggplot(data = data,aes(x =Relationship,y = N ))+
  geom_bar(stat = "identity",aes(frame = year))
ggplotly(p)

Can you modify my ggplot code to produce the same graph ？

This example runs successfully using frame parameter:

data(gapminder, package = "gapminder")
gg <- ggplot(gapminder, aes(gdpPercap, lifeExp, color = continent)) +
  geom_point(aes(size = pop, frame = year)) +
  scale_x_log10()
ggplotly(gg)

I get `Warning: Ignoring unknown aesthetics: frame`. What it's supposed to do? — Humpelstielzchen, Jun 07 '19 at 08:25
@Humpelstielzchen This `frame` parameter is for plotly ,not in ggplot2. — Tao Hu, Jun 07 '19 at 08:33
That's a bug I think. I have just opened an issue on Github to report it. — Stéphane Laurent, Jun 07 '19 at 11:18

In case others are still looking, this does appear to be a bug related to geom_bar. Per Stéphane Laurent's GitHub report (https://github.com/ropensci/plotly/issues/1544) a workaround is to use geom_col(position = "dodge2") or geom_col(position = "identity") instead of geom_bar(stat='identity')
