My ui.R file has a selectInput like this:
selectInput("variable1", "Choose Option:", camps)
where camps
is supposed to be a vector of options. This vector depends on a sql query that runs on the server script and returns the IDs of the camps:
server.R
df1 <- getCamps("date") camps <- unique(df1$idCamps)
When I run the App the ui.R does not know what "camps" is because it is only created in the server.R file. How can I pass the vector of camps created in the server.R file to the ui.R file so that they are now the options to choose from in the selectInput selector?
You need to create an input object in server.R, and return it to ui.R as part of the output
list:
In server.R:
df1 <- getCamps("date") camps <- unique(df1$idCamps) output$campSelector <- renderUI({ selectInput("variable1", "Choose Option:", as.list(camps)) })
In ui.R:
uiOutput("campSelector")
