nwos_total_apply: NWOS Total Apply
In bbutler01/nwos: NWOS Weights and Estimates

Description Usage Arguments References Examples

A version of the nwos_total function that is intended to be used with an apply function, typically for estimating sampling errors.

1	nwos_total_apply(r, index.rep, index, weight, area = 1, domain = 1, variable = 1)

`r`	vector of replicates numbers.
`index.rep`	list of observations (i.e., replicates) to include.
`index`	vector used to identify the location of values in the other vectors (e.g., row names).
`weight`	list of weights for each observation in each replicate.
`area`	vector of the area (of forestland) for each observation. Default = 1.
`domain`	vector with 1 indicating inclusion in the domain and 0 otherwise. Default = 1.
`variable`	vector of variable of interest. Default = 1.
