Deploying ToPan on Heroku

[abdrehman98]

I was trying to deploy ToPan on Heroku, I cloned the repo and installed dependencies locally and everything works fine. Then I used this buildpack https://github.com/virtualstaticvoid/heroku-buildpack-r, added dependencies to init.R file and also made a run.R file but my heroku app isnt working.

My init.R file:

init.R

Example R code to install packages if not already installed

my_packages = c("LDAvis", "XML", "xml2", "RCurl", "httr", "lda", "servr", "markdown", "data.table", "stringr", "plyr", "ggplot2", "jsonlite", "tsne", "DT")

install_if_missing = function(p) {
if (p %in% rownames(installed.packages()) == FALSE) {
install.packages(p)
}
}

invisible(sapply(my_packages, install_if_missing))

My run.R file:
library(shiny)
port <- Sys.getenv('PORT')
shiny::runApp(
appDir = getwd(),
host = '0.0.0.0',
port = as.numeric(port)
)
