我有一个问题,我导入一个大数据集,然后从该数据集生成一些选择输入,然后希望能够有一个图,我可以从数据中自由选择我的x轴和y轴组。
我一直在崩溃浏览器,使用我当前的代码 - 我相信rCharts试图生成多边形图,但变量尚不可用 - 我的自定义输入必须首先加载。我尝试过使用被动部件和隔离输出,以及其他东西 - 要么我做得不好,要么不正确 - 无论哪种方式都不起作用。
我对闪亮的R,特别是rCharts很新,但是我的图表只使用了一个输入 - 在尝试使多重选择时出现问题。
我有三个以下的UI,它们为renderCharts提供输入,我将在下面显示:
output$TestSelection <- renderUI({
selectInput("TestSel", "Test Variable", ls(df, pattern = ".*?_meas|.*?_calc"))
})
output$customx <- renderUI({
selectInput("xcustom", "Custom Graph - X", ls(df), selected = input$TestSel)
})
output$customy <- renderUI({
selectInput("ycustom", "Custom Graph - Y", ls(df), selected = input$TestSel)
})
renderChart2代码:
output$customplot <- renderChart2({
if(is.null(input$xcustom)|is.null(input$ycustom))
return(rCharts$new())
#Removing all unneccessary data from dataframe,
dataPlot <- df[,c("DUT", input$ycustom, input$xcustom)]
custom_chart <- rPlot(x = input$xcustom,y = input$ycustom,
data = dataPlot,
type = "point",
tooltip = "#!function(item){return item.DUT}!#",
sample = FALSE)
#Adjusting width to fit the current screen
custom_chart$set(width = session$clientData$output_plot2_width , title = paste(input$ycustom, " vs. ", input$ycustom, sep =""))
#Setting the correct axis
axisincrease = abs((max(dataPlot[,input$xcustom])-min(dataPlot[,input$xcustom]))*0.05)
custom_chart$guides(
x = list(
min = pretty(dataPlot[,input$xcustom])[1]-axisincrease,
max = tail(pretty(dataPlot[,input$xcustom]),1)+axisincrease,
numticks = length(dataPlot[,input$xcustom])
),
y = list(
min = pretty( dataPlot[, input$ycustom] ) [1],
max = tail( pretty( dataPlot[, input$ycustom] ), 1 )
)
)
return(custom_chart)})
