lookup

character string containing a regular expression to be matched
(see <code><a rd-options="" href="/link/grep?package=constants&version=0.0.1" data-mini-rdoc="constants::grep">grep</a></code>).

pattern

columns to perform pattern matching (see <code><a rd-options="" href="/link/codata?package=constants&version=0.0.1" data-mini-rdoc="constants::codata">codata</a></code>).

cols

additional arguments for <code><a rd-options="" href="/link/grep?package=constants&version=0.0.1" data-mini-rdoc="constants::grep">grep</a></code>.

A simple wrapper around <code><a rd-options="" href="/link/grep?package=constants&version=0.0.1" data-mini-rdoc="constants::grep">grep</a></code> for exploring the CODATA dataset.

CODATA internationally recommended values of the fundamental physical
constants, provided as symbols for direct use within the R language. Optionally,
the values with errors and/or the values with units are also provided if the
'errors' and/or the 'units' packages are installed. The Committee on Data
for Science and Technology (CODATA) is an interdisciplinary committee of the
International Council for Science which periodically provides the internationally
accepted set of values of the fundamental physical constants. This package
contains the "2014 CODATA" version, published on 25 June 2015:
Mohr, P. J., Newell, D. B. and Taylor, B. N. (2016)
<DOI:10.1103/RevModPhys.88.035009>, <DOI:10.1063/1.4954402>.
