could not find function viewer

[jeffreyevans]

I am receiving an error calling make_tile, where "viewer" does not seem to be a variable associated with getOption. I have options(help_type="html") set with no problem and it uses my default browser.

Hi!
viewer is an RStudio extension, are you running the code in the R GUI or a different IDE?
see here.

I may have to change the approach to launch the local html file in the viewer or browser
