 bash: syntax error near unexpected token `('

Answer 1

Check how you escape the quotes. The argument is:

"R -e \\"install.packages('shiny', repos='http://cran.rstudio.com/')\\""

This can be split into:

• "R -e \\"
• install.packages('shiny', repos='http://cran.rstudio.com/')
• \\""

The ( after packages is wrong shell syntax.

Do this:

sudo su - -c "R -e \"install.packages('shiny', repos='http://cran.rstudio.com/')\""
