我在sidebarLayout中遇到以下错误:以下脚本缺少参数“ mainPanel”,没有默认值:
library(shiny)
shinyUI(fluidPage(
titlePanel(title = "Pig breeding trends by country"),
sidebarLayout(
sidebarPanel(
mainPanel("2000 to 2010"),
sliderInput(inputId = "year",
label = "year by year count:",
min = 2000, max = 2010,
value = 1)
)
)
)
)
我检查了其他线程,这似乎是因为mainPanel不在sidebarLayout中,但是我已经检查了它,并将其放在方括号中,现在不确定该怎么做。
答案 0 :(得分:0)
这将起作用:
shinyUI(
fluidPage(
titlePanel(title = "Pig breeding trends by country"),
sidebarLayout(
sidebarPanel(
sliderInput(inputId = "year",
label = "year by year count:",
min = 2000,
max = 2010,
value = 1) ),
mainPanel())))
