Hi guy, I have a problem about ReactiverValues.
The thing is when I start to run the following code. There are two results show in RStudio Console:
[1] "I am here"
[1] "You are here"
What does it exactly do during the starting? why the two observes got triggered in the first place?
Best regards,
Song
I mean, why?
ui = fluidPage(
sidebarPanel(
numericInput("number" ,"set a number", 1))
)
server = function(input, output, session) {
reac <- reactiveValues(a = 1, b = 1)
observe({
reac$a <- isolate(input$number)
print("I am here")
})
observe({
reac$b
print("You are here")
})
}
shinyApp(ui, server)
