Failure to build package

[rrrlw]

R CMD build fails because package webshot is unavailable and not listed in the package dependencies list in multistateutils's DESCRIPTION file (in Imports or Suggests). Failure happens in lines 347-349. Note that after installing webshot, R CMD build still fails because a relevant connection cannot be opened (screenshot below of both errors in R CMD build; second call to R CMD build was after webshot was installed).

Edit: issue was reproduced on Ubuntu 18 and Windows 10 machines.

Part of this JOSS review.

I'm not sure about which of my dependencies requires webshot and why it isn't being installed automatically. I could add it to Imports if that would fix that first issue.

For the "Cannot open the connection" issue, I believe this is caused by being run as a script. I've removed this call from the Vignette and added a screenshot instead. Let me know if you can install it and run these lines in an interactive session.

On a side note, what is the preferred way of checking a package with Rcpp source? I generally used "Clean and rebuild" from RStudio then devtools::check(), which always ran successfully. I only got the connection error when manually running R CMD build.

Great! R CMD build now works perfectly for me, appears that the "Cannot open connection" issue is fixed. However, it seems that CRAN check is also having a problem with the webshot dependency. I think adding it to the Imports or Suggests field is reasonable (although it would likely also be a good idea to find out where it's being used).

Since CRAN seems to use R CMD build and R CMD check, those are what I prefer. However, I would expect that running devtools::check() with a clean environment would have identical behavior. Unsure what's happening...

Fix for #3 solves this issue as well.
