Hi, I am trying to install shiny packages from my R console using the command install packages ("shiny") but i got this error, what it means? how can I install shiny from R ?
That means you are running the install from a regular account (i.e. non-root). You can accept the suggestion from the installer and use a personal ($HOME) location.
It's not an error, it's just a question. It's one of the things I love about R, how easy it is to install packages as non-root/user. The package (if you accept) will be installed just for you.
