Description Usage Arguments Details Value Examples

Expand a chain into a series of lines, each with . as the input.

expand_chain(ex)

expand_all_chains(ex)

chain_elements(ex)

is_chain(ex)

`ex`	A `checkr_result` object with just one line of code.

A magrittr chain consists of a sequence of function calls. Each function takes as input the output of the function before it. (The first element of the chain may be an object or a function call.) The expand_ functions transform chains into a sequence of lines. Each such line (except the first) will be a function with at least one of the inputs being denoted .. The value of . for each line will be the object that is an input to that line.

A checkr_result object with one line for each of the functions in the chain.
