So a little background. I have a Shiny web app that I wrote for the benefit of easing the work for people who's afraid of programming.
in the course of building it I decided on embedding a rmarkdown document explaining how to use of the application.
so far everything worked (it took months to build and perfect but it worked).
now i decided to relieve people from opening Rstudio at all! using this link - Running a Shiny app using a shortcut
but now i came across a problem I'm afraid I am not able to solve.
when you run the app through shiny, everything works, but when you use the link, it runs with an error: pandoc document conversion failed with error 127
my app.r looks like this:
library(shiny)
library(knitr)
ui <- fluidPage(
titlePanel("testing for error"),
sidebarPanel(
textInput(inputId = "year",label = "Year",placeholder = "2018")
),
mainPanel(
uiOutput("report")
)
)
server <- function(input, output) {
output$report <- renderUI({
year <- input$year
rmdfiles <- c("C:\\Users\\ge_a\\Desktop\\test\\report_test.Rmd")
knitr::knit2pandoc(input = rmdfiles,encoding = "UTF-8",quiet = TRUE)
includeMarkdown("C:\\Users\\ge_a\\Desktop\\test\\report_test.md")
})
}
shinyApp(ui = ui, server = server)
as you can see there's a rmarkdown file embedded in the app, it includes letters in hebrew. the markdown file also uses arguments given by the user.
this is the rmarkdown script (which basically just says: "our year is [input of the current year]"):
---
title: "Test"
author: "Abe"
date: "August 20, 2018"
output: html_document
---
<style>
h1 {
direction: rtl;
}
p {
direction: rtl;
color: #000000;
font-size: 14px;
}
</style>
השנה שלנו היא: `r year`
using the link I mentioned above I created a run.r file and batch file for the purposes of creating a shortcut people can use.
My run.r file is this:
library(shiny)
Sys.setlocale("LC_ALL","hebrew")
runApp('C:/Users/ge_a/Desktop/test',launch.browser = TRUE)
and the test.bat file is only 1 line:
"C:\Program Files\R\R-3.4.2\bin\R.exe" CMD BATCH "run.r"
Here is the sessionInfo output so you can see which platform and libraries I'm running:
