如何在相同的图表图表上组合线条和散点图？

使用R plotly包创建时,从data.frame创建的两个单独的图表正常工作.
但是,我不确定如何将它们组合成一个(大概是使用add_trace函数)

df <- data.frame(season=c("2000","2000","2001","2001"), game=c(1,2,1,2),value=c(1:4))

plot_ly(df, x = game, y = value, mode = "markers", color = season)
plot_ly(subset(df,season=="2001"), x = game, y = value, mode = "line")

提前致谢

@LukeSingham给出的答案不再适用了plotly 4.5.2.你必须以"空"开头,plot_ly()然后添加痕迹:

df1 <- data.frame(season=c("2000","2000","2001","2001"), game=c(1,2,1,2), value=c(1:4))
df2 <- subset(df, season=="2001")

plot_ly() %>% 
  add_trace(data=df1, x = ~game, y = ~value, type="scatter", mode="markers") %>% 
  add_trace(data=df2, x = ~game, y = ~value, type="scatter", mode = "lines")
