##### Summarise function complexity of a file or environment

Summarise function complexity of a file or environment

##### Usage
sig_report(x, ...)
"sig_report"(x, ...)
"sig_report"(x, too_many_args = 10, too_many_lines = 50, ...)
"sig_report"(x, ...)
"print"(x, ...)
##### Arguments
x
A path to an R file or an environment.
...
Passed to sig_report.environment.
too_many_args
Upper bound for a sensible number of args.
too_many_lines
Upper bound for a sensible number of lines.
##### Details

sig_report summarises the number of input arguments and the number of lines of each function in an environment of file, and identifies problem files, in order to help you refactor your code. If the input is a path to an R file, then that file is sourced into a new environment and and the report is generated from that. The number of lines of code that a function takes up is subjective in R; this function uses length(deparse(fn)).

##### Value

An object of class sigreport'' with the elements.
• n_varsNumber of variables.
• n_fnsNumber of functions.
• n_argsTable of the number of args of each function.
• too_many_argsUpper bound for a sensible number of args.
• fns_with_many_argsNames of each function with more args than too_many_args.
• n_linesTable of the number of lines of each function body.
• too_many_linesUpper bound for a sensible number of lines.
• long_fnsNames of each function with more lines than too_many_lines.
