Easy Condition Handling (attempt)
A friendlier condition handler, inspired by ‘purrr’ mappers and based on ‘rlang’. ‘attempt’ extends and facilitates condition handling by providing a consistent grammar, and provides a set of easy to use functions for common tests and conditions. ‘attempt’ only depends on ‘rlang’, and focuses on speed, so it can be easily integrated in other functions and used in data analysis.

Read, Manipulate, and Write Profiler Data (profile)
Defines a data structure for profiler data, and methods to read and write from the ‘Rprof’ and ‘pprof’ file formats.
