r - Combine ggplotly and ggplot with patchwork?

Question

Is it possible to combine a ggplotly and a ggplot with patchwork?

Example

This displays the two plots side by side

library(ggplot2)
library(plotly)
library(patchwork)

a <- ggplot(data.frame(1), aes(X1)) + geom_bar()
b <- ggplot(data.frame(1), aes(X1)) + geom_bar()
a + b

But if we convert one to ggplotly, it errors

b  <- ggplotly(b)
a + b
Error: Can't add `b` to a ggplot object.
Run `rlang::last_error()` to see where the error occurred.

Is there a way to work around this?

Plotly 具有subplot将多个绘图组合在一起的功能：

library(ggplot2)
library(plotly)

df1 <-data.frame(x=1:10, y=1:10)
df2 <- data.frame(x=10:1, y=1:10)

p1<-ggplot(df1, aes(x, y)) +geom_point()
fig1<-ggplotly(p1)

p2<-ggplot(df2, aes(x, y)) +geom_line()
fig2<-ggplotly(p2)

subplot(fig1, fig2, nrows=2)
