ggplot使用来自datatable(DT)和reactive小部件的过滤数据来选择x轴和y轴
我想使用datatable中过滤的数据来创建ggplot。我还实现了两个小部件,在过滤数据表之后,它们将允许用户选择x&y轴来显示。在设置小部件等之后,我遇到了一个错误:ggplot使用来自datatable(DT)和reactive小部件的过滤数据来选择x轴和y轴,r,ggplot2,datatable,shiny,dt,R,Ggplot2,Datatable,Shiny,Dt,我想使用datatable中过滤的数据来创建ggplot。我还实现了两个小部件,在过滤数据表之后,它们将允许用户选择x&y轴来显示。在设置小部件等之后,我遇到了一个错误: Error in `[.data.frame`(data_melt, filtered_data) : undefined columns selected 我不知道为什么会这样 我的数据示例: Rundheit Diff Charge Ord..Nr. Block.Nr.
Error in `[.data.frame`(data_melt, filtered_data) : undefined columns selected
我不知道为什么会这样
我的数据示例:
Rundheit Diff Charge Ord..Nr. Block.Nr.
1 0.24 0.20 754331 738 1
2 0.26 0.21 783345 738 2
3 0.25 0.15 795656 738 3
4 NA 0.14 798431 738 4
5 NA 0.12 799651 738 5
6 0.24 NA 805454 738 6
NA值必须保留在我的数据中
用户界面:
不工作,例如使用:
data_filt <- data_melt[filtered_data, ]
Error in seq.int(0, to0 - from, by) : 'to' cannot be NA, NaN or infinite
以及:
data_filt <- data_melt[filtered_data, input$xaxis]
我需要输入$yaxis
并将其实现。。。
因此,我尝试:
data_filt <- data_melt[filtered_data, c(input$xaxis, input$yaxis)]
我用这段代码播放了一段信息,即使指定了列的名称,它也会抛出一个错误,我甚至不能指定多个
我尝试过以下方法:
[filtered_data, "Rundheit")
[filtered_data, c("Rundheit", "Diff")]
非常感谢您提供的任何想法因此您的代码有点“凌乱”,有一些编译器错误,一些代码缺失,我不得不手工输入您的数据。不是每个人都会这么做。。。我也不确定data
和data\u-melt
的事情应该发生在哪里,所以我选择了data\u-melt
。不管怎样,我让它工作了,我必须承认这是一个强大而迷人的功能。我希望这是您想要的,尽管我没有看到您所有的错误消息本身
您的主要错误是设置了rownames=F
,因为input$tabelle\u rows\u all
使用这些行名来过滤表。我还向ggplot
调用添加了一个nrow
保护,以防止它被空数据帧阻塞

未关闭。请修复。对不起,我只是复制了我的代码没有完全。。renderPlot在我的脚本中是关闭的。当问问题时,最好提供一个最低限度的工作示例。感谢tipp,对不起,我是新来的。我刚刚更新了我的帖子。这个答案有用吗?
