R 在SelectizeInput中筛选多个输入的数据帧
我有一个闪亮的应用程序,它根据用户选择的人口统计显示了名为R 在SelectizeInput中筛选多个输入的数据帧,r,dataframe,reactive-programming,shiny,R,Dataframe,Reactive Programming,Shiny,我有一个闪亮的应用程序,它根据用户选择的人口统计显示了名为demographicsdata的数据框中的各种指标 5个地理位置的样本数据- 人口统计数据 structure(list(Geography = c("AK", "AL", "AR", "AZ", "CA"), `Sum of Total Persons` = c(855385L, 5293523L, 3766990L, 6420943L, 37431000L), `Sum of Total Families2` = c(19

当只选择了一个人口统计时,该应用程序可以完美运行,但当我尝试将多个选择引入selectizeInput框时,它崩溃了
下面是整个代码的一个最小示例
应用程序r
ui有两件事需要改变
1) 在selectizeInput
2) 将%
中的==
替换为%in%
,以进行多个元素的比较

ui感谢您的支持!!无论如何,我可以将输出显示为所选输入的集合吗?我希望输出在一个实例中显示整个AL AZ的总人口总数,而不是在每个输入选择中显示一个低于另一个。例如,上述输出必须显示:总人口=583824@AshwinRamesh在这种情况下,只需执行求和
。更新了帖子你是个救生员谢谢!!我不知道为什么我没有想到这一点,我想我只是盯着这个看太久了。
