[R] Help for funnel plot

[Rui Barradas]

Hello,

No attachment came through, see the posting guide (a link is at the 
bottom of this and every R-Help e-mail) for the file formats allowed in

What do you mean by colour gradient? `metafor::funnel` has 3 arguments 
to set colors,

  - back, set in your code to 12;
  - shade, unused;
  - hlines, unused.

And when you use functions not in base R, start your scripts with calls 
to library() to load the packages where those functions can be found.


Hope this helps,

Rui Barradas
