An error in deploying shiny app to Shinyapps.io

Question

I have a Shiny app that uses the following packages in the server.R file.

library(shiny)      #Creating the app 
library(ggplot2)    
library(plyr)       
library(reshape2)
library(scales)
library(grid)
library(data.table)
library(pracma)
library(dplyr)

The app runs without any errors inside Rstudio; however, it gave an error (below) when I tried to upload it. It seems that the error is related to the dplyr package. It uploads successfully when I remove the dplyr package. I need the dplyr and plyr package to do some calculations in the server.R script.

N.B. The scripts for server.R and ui.R are very long and hard to include in the question here.

Is there anybody who had similar issue? What is the thing that is going wrong here and how can I deal with it?

Here is the errror that I've got in Rstudio upon uploading the Shiny app:

library(rsconnect)
library(shinyapps)
deployApp()

Answer 1

I found a solution for my problem. The dplyr package requires the Rcpp package to be installed. So first install the Rcpp package then deploy the app.

install.packages("Rcpp")
deployApp()
