record_print {xfun}

Print methods for record()

Description

An S3 generic function to be called to print visible values in code when the code is recorded by record(). It is similar to knitr::knit_print(). By default, it captures the normal print() output and returns the result as a character vector. The knitr_kable method is for printing knitr::kable() output. Users and package authors can define other S3 methods to extend this function.

Usage

record_print(x, ...)

## Default S3 method:
record_print(x, ...)

new_record(x, class)

Arguments

x

For record_print(), the value to be printed. For new_record(), a character vector to be included in the printed results.

...

Other arguments to be passed to record_print() methods.

class

A class name. Possible values are xfun:::.record_cls.

Value

A record_print() method should return a character vector or a list of character vectors. The original classes of the vector will be discarded, and the vector will be treated as console output by default (i.e., new_record(class = "output")). If it should be another type of output, wrap the vector in new_record() and specify a class name.
