rshinyr-highcharter
highchart not rending in rshiny but is working in my directory
I am trying to reproduce the decomposed time series plot with highchart. The result is perfect in the working directory of r but when I put it in r shiny no result comes out. Here is my code
library(shinyjs)
library(shiny)
library(shinydashboard)
library(highcharter)
library(forecast)
shinyOptions(bslib = TRUE)
bs_global_theme()
bs_theme_base_colors(bg = "#002B36", fg = "#EEE8D5")
bs_theme_accent_colors(primary = "#2AA198")
thematic::thematic_shiny()
ui<-fluidPage(
theme=shinytheme("cerulean"),
themeSelector(),
useShinyjs(),
navbarPage(
title= "Stock exchange", position = "static-top",
id="nav",
tabPanel("Single stock analysis",value = "single_stock", icon = icon("chart-area"),
sidebarLayout(
div(id = "Sidebar",
sidebarPanel(width = 3, align = "center",
selectInput("ticker",
strong("Ticker"),
# quotes$Symbole,
choices = c("AirPassengers", "ttrc"),
selectize = TRUE
),
dateRangeInput("date", strong("Select data range"),
start = "2012-01-01", end = (Sys.Date()-1)
),
tags$br(),
fluidPage(column(width = 3, "Session")
)
)),
mainPanel(
fluidRow(align = "center",
selectInput("hideorshow", label = strong("Sidebar disposition"),
choices = c("Show", "Hide"), selected = "Show")),
tabsetPanel(
tabPanel("Data structure and summary",
icon = icon("table"),
h1(align = "center",
strong(" STRUCTURE OF THE DATAFRAME ")),
tags$br(),tags$b(),class="fa fa-table",
verbatimTextOutput("struc"),
tags$br(),tags$br(),
h1(align = "center",strong(" SUMMARY OF THE DATAFRAME ")),
br(),verbatimTextOutput("summary1")
),
tabPanel("Dataset",icon = icon("tablet-alt"), DTOutput('tbl1')),
tabPanel("Plot",icon = shiny::icon('chart-bar'), br(),br(), br(),
airDatepickerInput(inputId = "date.ts",
strong("Time of the first observation"),
value = "2017-01-01",
minDate = "1998-09-16",
maxDate = Sys.Date(),
view = "months",
minView = "months",
dateFormat = "yyyy-mm"),
highchartOutput("closing_pr.ts",width = "auto", height = "600px"),
),
)
)
)),
tabPanel("Multiple stocks analysis", tabName = "mult_stock", icon = icon("th"))
)
)
I think the problem is hide in the server; exactely the renderHighchart but i can't find it. Please any help will be appreciate.
