print() to debug againIcecream provides a more user-friendly print debugging experience. Use ic() wherever you would
use print() and see the expression and its value easily.
The following options can be used to control behaviour:
icecream.enabled: Boolean. If FALSE, calls to ic(foo) simply evaluate and return foo.
No output is printed.
icecream.prefix: This is printed at the beginning of every line. Defaults to "ic|".
icecream.include.context: Boolean. If TRUE, when calling ic(foo) the source file:line
or environment will be printed along with the expression and value. This can be useful for more
complicated debugging but produces a lot of output so is disabled by default. When ic() is
called with no arguments, the context is always printed because showing the location of the
call is the only reason to call ic() on its own.
icecream.peeking.function: indicates the function that summarizes the object. Default value
is ic_autopeek, which works like utils::str for most of the time, but gives more
informative output for lists, data.frames and their subclasses in a more compact way.
icecream.max.lines Integer. Determines maximum number of lines that the peek of an object
occupies; defaults to 1.
icecream.output.function: Not implemented yet. See the
configuration section of the original
project docs for details of what it will do.
icecream.arg.to.string.function: Not implemented yet. See the
configuration section of the original
project docs for details of what it will do.
