abund.manycensus: Collect abundances of all species across several censuses.

In forestgeo/ctfs: Tools for the Analysis of Forest Dynamics

Description

Collect abundances of all species across several censuses.

Usage

abund.manycensus(allcns = list(bci.full1, bci.full2, bci.full3), mindbh,
  dbhunit = "mm", type = "abund", excludespp = NULL,
  excludestatus = NULL)

Arguments

allcns	Full R census, submitted as a list (as many as desired).
mindbh	The minimum diameter above which the counts are done. Trees smaller than mindbh are excluded. If NULL, all living trees are included.
dbhunit	'cm' or 'mm', only used for basal area
type	Either 'abund' (default) for abundance, 'ba' for basal area, or 'agb'.
excludespp	A character vector of species codes can be submitted as excludespp, for instance those for unidentified trees.
excludestatus	By default, any tree ever given code M is not counted in any census, but set excludestatus = NULL to include them.

Examples

## Not run: 
N = abund.manycensus(
  allcns = list(
    bciex::bci12t1mini, bciex::bci12t2mini, bciex::bci12t3mini, bciex::bci12t4mini
  ),
  mindbh = 10,
  type = 'abund',
  excludespp = 'uniden',
  excludestatus = 'M'
)
head(N)
colSums(N)
apply(N,2,countspp)

N = abund.manycensus(
  allcns = list(bciex::bci12t5mini, bciex::bci12t6mini),
  mindbh = 10,
  type = 'abund',
  excludespp = c('uniden', 'tremxx'),
  excludestatus = NULL
)
