[英]Shiny selectInput from column DF
Currently i am working on my own shinydashboard. 目前,我正在开发自己的Shinydashboard。 And i would like to ask you for help. 我想向您寻求帮助。 I would like to show Data_Location()$Address
in my inputbox that is corresponding to Data_Location()$Location_skey
. 我想在我的Data_Location()$Address
显示与Data_Location()$Location_skey
对应的Data_Location()$Address
。 Normally you can do it like this: 通常,您可以这样做:
selectInput("KPI", "Choose a KPI:", choices = c("Aantal Sessies Aansluiting"="AantalSessiesAansluiting",
"Aantal Unieke RFIDS Aansluitingg"="AantalUniekeRFIDsAansluiting",
"Beschikbare Dagen Aansluiting"="BeschikbareDagenAansluiting",selected="")
The difference is that I want to use a dataframe column. 区别在于我要使用数据框列。
head(Data_Location()$Location_skey)
[1] -1
[2] 1
[3] 2
[4] 3
[5] 4
head(Data_Location()$Address)
[1] onbekend
[2] Putstraat 86
[3] 1e De Riemerstraat 1
[4] Van Spaenstraat 23
[5] Suze Groeneweglaan 323
selectInput("location", "Selected a charge point",choices =c("",Data_Location()$Location_skey), selected="")
I would like to thank you for reading this post and I would be very pleased if you could help me out. 非常感谢您阅读这篇文章,如果您能帮助我,我将非常高兴。

I think this is what you want: 我认为这是您想要的:
library(shiny)
ui <- fluidPage(
selectInput("sip","select",choices=1:3)
)
server <- function(input,output,session){
df <- data.frame(cnames=c("a","b","c"),keys=c(1,2,3))
chlst <- df$keys
names(chlst) <- df$cnames
updateSelectInput(session,"sip",label="label",choices=chlst)
}
shinyApp(ui,server)
