我创建了一个闪亮的应用程序，其中包含三个重要按钮。

三个按钮效果很好

click3 可以输出一个绘图和一个表格。

现在在我的应用程序中，他们只是互相刷新，但每次只有桌子仍然存在。

我的问题是现在我想修改一些部分，我希望：

plot1 和 plot2 不会刷新 click3（plot3 和 table），并且 click3 不会刷新 plot1 或 plot2。

抱歉，我没有澄清我的问题。

现在p1(),p2(), myPlot可以互相刷新了。

但我希望myPlot并且myTable可以一直呆到新的click3刷新自己。p1() and p2()可以互相刷新但不会影响myPlotandmyTable 所以p1() or p2()可以myPlot和myTablemainparnel 保持在一起。

我的可重现代码和数据在这里：

library(shiny)
library(ggplot2)
##  load("04.21_3.RData")

mean_data <- data.frame(
  Name = c(paste0("Group_", LETTERS[1:20])),
  matx <- matrix(sample(1:1000, 1000, replace = T), nrow = 20)
)
names(mean_data)[-1] <- c(paste0("Gene_", 1:50))

sd_data <- data.frame(
  Name = c(paste0("Group_", LETTERS[1:20])),
  matx <- matrix(runif(1000, 5, 10), nrow = 20)
)
names(sd_data)[-1] <- c(paste0("Gene_", 1:50))

也许这是你的期望

names(mean_data)[-1] <- c(paste0("Gene_", 1:50))

sd_data <- data.frame(
  Name = c(paste0("Group_", LETTERS[1:20])),
  matx <- matrix(runif(1000, 5, 10), nrow = 20)

names(sd_data)[-1] <- c(paste0("Gene_", 1:50))
