Question

Trying this

MetaOmics tutorial using R language in windows

But after installation of "shiny package" when trying this script

shiny::runApp('metaOmics', port=9987, launch.browser=T)

it is showing Error

Error in loadNamespace(name) : there is no package called ‘shiny’

How to solve this problem?

What did it say when you ran install.packages(shiny)? I am guessing the shiny installation was unsuccessful.

install.packages("shiny")

how to install it properly?

[Dunois]

As your output indicates, you need to install Rtools first. Take peek here if you need to figure out how to to install it on a Windows machine. Try installing shiny after that, and it should probably work assuming no other prerequisites are unsatisfied.
