I'm very new to Shiny, so this could be a simple mistake on my part. I'm getting a warning when I try to deploy the app that there is a probelm accessing the CRAN repository. This is the warning:
Warning: unable to access index for repository https://cran.rstudio.com/src/contrib: cannot open URL 'https://cran.rstudio.com/src/contrib/PACKAGES ... * Unable to determine the location for some packages. Packages must come from a package repository like CRAN or a source control system. Check that options('repos') refers to a package repository containing the needed package versions.
Oddly, the warning lists out the warning for every library I've ever installed (where I inserted "..." above), although I'm only using a couple libraries in my app:
When I run options('repos'), I get this:
$repos CRAN "https://cran.rstudio.com/" attr(,"RStudio")  TRUE
Has anyone had a similiar problem? Or have a suggestion on how to get my app to deploy? Thanks in advance!
