Style code according to the tidyverse style guide.
The extent of manipulation. Can range from "none" (least
invasive) to "tokens" (most invasive). See 'Details'. This argument is a
string or a vector of class
A logical value indicating whether a set of strict
or not so strict transformer functions should be returned. Compare the
functions returned with or without
strict = TRUE. For example,
strict = TRUE means force one space e.g. after "," and one line break
e.g. after a closing curly brace.
strict = FALSE means to set spaces and
line breaks to one if there is none and leave the code untouched otherwise.
How many spaces of indention should be inserted after operators such as '('.
Whether or not comments should start
with only one space (see
A list of parameters for regex re-indention, most
conveniently constructed using
A list of parameters that define spacing around
math token, conveniently constructed using
The following levels for
scope are available:
"none": Performs no transformation at all.
"spaces": Manipulates spacing between token on the same line.
"indention": Manipulates the indention, i.e. number of spaces at the beginning of each line.
"line_breaks": Manipulates line breaks between tokens.
"tokens": manipulates tokens.
scope can be specified in two ways:
As a string: In this case all less invasive scope levels are implied, e.g. "line_breaks" includes "indention", "spaces". This is brief and what most users need.
As vector of class
AsIs: Each level has to be listed explicitly by
wrapping one ore more levels of the scope in
I(). This offers more
granular control at the expense of more verbosity.
See 'Examples' for details.
