Typographic Conventions

Throughout this GitBook, we (try to) use a consistent set of typographic conventions:

• Functions are typeset in a code font, and the name of the function is always followed by parentheses
  • E.g., sum(), mean()
• Other R objects (e.g., data objects, function arguments) are in also typeset in a code font but without parentheses
  • E.g., seTE, method.tau
• Sometimes, we’ll use the package name followed by two colons (::, the so-called *scope-resolution operator), like lavaan::sem(). This command is valid R code and will run if you copy it into your R console. The lavaan:: part of the command tells R that we want to use the sem() from the lavaan package.
