R 嵌入具有混合数字输入的列,并在DT中选择输入
我想在DT中添加一列,该列接受selectInput或NumericiInput,具体取决于变量。 例如,给定以下DF:R 嵌入具有混合数字输入的列,并在DT中选择输入,r,shiny,dt,R,Shiny,Dt,我想在DT中添加一列,该列接受selectInput或NumericiInput,具体取决于变量。 例如,给定以下DF: df1 <- tibble( var1 = sample(letters[1:3],10,replace = T), var2 = runif(10, 0, 2), id=paste0("id",seq(1,10,1)) ) DF=gather(df1, "var", "value", -id
df1 <- tibble(
var1 = sample(letters[1:3],10,replace = T),
var2 = runif(10, 0, 2),
id=paste0("id",seq(1,10,1))
)
DF=gather(df1, "var", "value", -id)
df1这里是的一个改编版本
使用最新版本的tidyr
中推荐的pivot\u longer
代替collect
。此外,在为新的选择器
列创建输入时,请检查变量名称
。如果是var1
使用选择输入
,否则使用数值输入
否则,应该以类似的方式工作
