如何在R中更新来自两个不同来源的数字输入？

我正在尝试构建一个简单的闪亮应用程序，在这里我可以从建筑中的加热系统获取当前的加热曲线，并将其可视化到绘图中。使用4个数字输入字段（2个x坐标值和2个y坐标值）手动执行此操作

另外还有两个不同的问题（在本例中使用单选按钮），我应该得到一个新的当前加热曲线的建议，在这里我可以对我的加热系统进行一些更改。新值（从第一个NumericiInput和单选按钮计算得出）应显示在4个附加NumericiInput字段中（这已在使用updateNumericInput（）和ObserveeEvent（）

此外，当我输入信息（单选按钮）后显示第一条建议时，我希望能够在第二部分中使用4个数字输入调整新曲线。这是我目前面临的挑战。这些字段在我定义信息（单选按钮）后被阻止

下面我列出了我的代码

谢谢你的帮助

我还尝试使用矩阵提前计算每个不同的选项，并仅参考正确的矩阵行绘制直线（段（…）。另外，我尝试在没有observeEvent函数的情况下覆盖numericInput变量，但也没有成功
