Not able to deploy shiny app in rstudio server

Question

I was trying to run a shiny app in RStudio but everytime i tried to run the document it refuses to run it saying

error in library(shiny) : there is no package called ‘shiny’

This happens also after i installed the shiny app.

    Installing package into ‘/home/mrshekar/R/x86_64-pc-linux-gnu-library/3.4’
(as ‘lib’ is unspecified)
trying URL 'https://cloud.r-project.org/src/contrib/shiny_1.1.0.tar.gz'

Warning in install.packages :

The downloaded source packages are in

Something similar happens when i try to deploy the shiny web app in the server. It says

Download the Shiny app now?

Everytime i start a new app eve after i have installed the packages. Please help. Thanks

Answer 1

It already happened to me. I don't know why, but R was not able to install shiny. So the thing i did is to install it manually. I mean, just download the package from here: https://cran.r-project.org/web/packages/shiny/index.html and paste the shiny folder in C:\\Users\\your_username\\Documents\\R\\win-library\\3.3. If it doesn't work, just install the dependencies.

The answer in Can't install ggplot2 at debian 7.6 in R works. But after you do that manually enter all the packages you want to install in it
