我有一个数据集,我想形象化的整体和几个不同的变量分类。我创建了一个flexdashboard,其中包含一个toy-shinny应用程序来选择分解类型,并使用工作代码来绘制正确的子集。
我的方法是重复的,这对我来说是一个暗示,我错过了一个更好的方法来做到这一点。让我感到困惑的是需要按日期计数并扩展矩阵。我不知道如何得到一个管道每周计数组。我把它分为几个步骤并结合起来。
思想?
(附:我是在星期五问这个问题的
RStudio Community
但我觉得这更像是
SO question
". 我没有权限从RSC中删除它,所以很抱歉交叉发布。)

更新:
@jonspring建议编写一个函数来减少一些重复(应用于下面),这是一个很好的改进。不过,基本方法是相同的。分段、计算、合并、绘图。有没有办法做到这一点而不拆散和重新组装?
