colorize

Add ANSI color to a string using the 
<code>crayon</code> package, if the R environment accepts color. 
This function is needed because of the need to determine whether 
output can be colorized. This determination is left up to 
<code><a href="/link/crayon%3A%3Ahas_color()?package=Rdistance&version=4.0.5" data-mini-rdoc="Rdistance::crayon::has_color()">crayon::has_color()</a></code>.
In addition, for Rdistance results, we want to only colorize 
numbers, not the reporting units. Everything between the last set 
of square brackets (<code>[...]</code>) is NOT colorized.

Distance-sampling (<doi:10.1007/978-3-319-19219-2>)
estimates density and abundance of survey targets (e.g., animals) when
detection probability declines with distance.
Distance-sampling is popular in ecology,
especially when survey targets are observed from aerial platforms (e.g.,
airplane or drone), surface vessels (e.g., boat or truck), or along
walking transects.
Distance-sampling includes line-transect studies that measure observation
distances as the closest approach of the sample route (transect) to the target
(i.e., perpendicular off-transect distance), and point-transect studies that
measure observation distances from stationary observers to
the target (i.e., radial distance).
The routines included here fit smooth (parametric) curves to
histograms of observation distances
and use those functions to compute effective sampling distances, density of
targets in the surveyed area, and abundance
of targets in a surrounding study area. Curve shapes include the
half-normal, hazard rate, and negative exponential functions.
Physical measurement units are required and used throughout to
ensure density is reported correctly. The help files
are extensive and have been vetted by multiple authors.

colorize function

<dl><dt>STR</dt>
<dd>The string to colorize.</dd>
<dt>col</dt>
<dd>A string specifying the desired foreground color.
This is passed straight to <code><a href="/link/crayon%3A%3Astyle?package=Rdistance&version=4.0.5" data-mini-rdoc="Rdistance::crayon::style">crayon::style</a></code> and so must be 
recognized as one of the 8 base crayon colors. i.e., 
"black", "red", "green", "yellow", "blue", "magenta", "cyan", 
"white", and "silver" (silver = gray). By default, numbers 
are styled in "green".</dd>
<dt>bg</dt>
<dd>A string specifying the desired background color. 
Must be one of "bgBlack", "bgRed", "bgGreen", "bgYellow", "bgBlue"
"bgMagenta", "bgCyan", or "bgWhite". By default, no background 
is applied.</dd></dl>
