Summarize number of sightings and animals for selected species by segment
airdas_effort_sight(x.list, sp.codes, sp.events = c("S", "t"))
x.list |
list; output of |
sp.codes |
character; species code(s) to include in segdata.
These code(s) will be converted to lower case to match |
sp.events |
character; event code(s) to include in the sightinfo output. This argument supersedes the 'included' value when determining whether a sighting is included in the segment summaries. Must be one or more of: "S", "t" (case-sensitive). The default is that all of these event codes are kept |
This function takes the output of airdas_effort
and
adds columns for the number of sightings (nSI) and number of animals (ANI)
for selected species (selected via sp.codes
) for each segment
to the segdata element of x.list
.
However, only sightings with an included value of TRUE
(included is a column in sightinfo) are included in the summaries.
Having this step separate from airdas_effort
allows users to
personalize the included values as desired for their analysis.
A list, identical to x.list
except for
1) the nSI and ANI columns added to x.list$segdata
,
one each for each element of sp.codes
, and
2) the included column of x.list$sightinfo
, which has been set as
FALSE
for sightings of species not listed in sp.codes
