failure value: 127

Hi,

This is a great tool! Thanks.

I am having an issue when using webshot function:

> webshot("https://www.r-project.org/", "r.png")
sh: ~/Library/Application Support/PhantomJS/phantomjs: No such file or directory
Error in webshot("https://www.r-project.org/", "r.png") : 
  webshot.js returned failure value: 127

In function phantom_run, if using the full path of phantomjs (/Users/username/.../phantomjs instead of ~/.../phantomjs), the function is working as expected.

KR,
David

It sounds like ~ is not being expanded. @yihui, perhaps this is because of the shQuote that was added?

Thanks for the report! I just expanded ~. For OS X, I recommend you to install PhantomJS via Homebrew instead. It is easier to install and manage in the future.

OK,
thanks again!
