R:Shiny - 无功输出在 grid.arrange(from gridExtra) 中不起作用

Question

我正在使用 gridExtra 结合 Ggplot 的条形图制作摘要图。

问题是我想让摘要对 radioButtons 输入有反应。

我想要实现的目标:

我有什么:

我确定是因为使用了我在服务器中使用的“input$radio”部分。R:

shiny::runApp()

Listening on http://127.0.0.1:7548
Warning in grob$wrapvp <- vp : Coercing LHS to a list
Error in gList(structure(list("tbl.precio.nuevo", wrapvp = structure(list( : 
  only 'grobs' allowed in "gList"

有什么办法解决这个问题吗？

Answer 1

我测试了它，这有效:

# add after g
gg <- ggplotGrob(g)
if(input$radio=="tbl.precio.nuevo"){
    g1 <- gtable::gtable_add_grob(gg, grobs = tbl.precio.nuevo 
                              ,t=6, l=6, b=5, r=2
                              )
} else {
    g1 <- gtable::gtable_add_grob(gg, grobs = tbl.precio.antes 
                                  ,t=6, l=6, b=5, r=2
    )
}
grid::grid.draw(g1)
