Good evening.
I would like to use the ichimiko package for an interactive visualization in r shiny.
I would like that every time the user choose a sticker, the graphic can change automatically.
When I put the code in the ui interface I get the following error ('cloud not existing').
But if I save the code before running the shinyApp, the code work Well. I get the graphic but the plot IS very great
ichimoku(getSymbols("AAPL", src = "yahoo", from=start_date, to=end_date, auto.assign=F))-> cloud
Below is the code.
library(ichimoku)
library(shiny)
library(quantmod)
start_date <- Sys.Date()-365
end_date <- Sys.Date()
ui <- fluidPage("Stock market",
titlePanel("Stop market App"),
sidebarLayout(
sidebarPanel(
textInput("Stock","Input Stock"),
selectInput("Stock", label = "Stock :", choices = c("DIA",
"MSFT",
"FB",
"AAPL",
"GOOG"), selected = "AAPL", multiple = FALSE),
actionButton("GO","GO")),
mainPanel(br(),
h2(align = "center", strong("ICHIMOKU CLOUD PLOT")),
iplot(cloud, width = 1000, height = 1000)
)))
server <- function(input, output, session){
cs <- new.env()
data <- eventReactive(input$GO,{
req(input$Stock)
getSymbols(input$Stock, src = "yahoo",
from=start_date, to=end_date, auto.assign=F)
})
cloud1 <- reactive({
dt<- data()
cloud <- ichimoku(dt)
})
cloud <- ichimoku(cloud1(), ticker = input$Stock)
}
shinyApp(ui = ui, server = server)```
IS it also possible to fix the bslib at the left and down side?
[Ichimoku library vignette](https://cran.r-project.org/web/packages/ichimoku/vignettes/reference.html)
I just copy a little part of the code.
