estimate_allgaps: Estimate annual & perennial canopy gaps from perennial canopy...

In annack84/STMdevelopment: Develop State-and-Transition Models for the Upper Colorado River Basin

Estimate annual & perennial canopy gaps from perennial canopy gaps and LPI cover data with a linear model built by Joe Brehm, to be published in McCord et al. (in prep as of 10/2023). All estimates require values for (1) the perennial gap window that matches the annual & perennial gap window to be estimated (e.g. to estimate annual gaps > 25 cm, use perennial gaps > 25 cm), (2) annual grass cover, (3) perennial grass cover, (4) shrub cover, and (5) forb cover. All cover variables should come from any-hit indicators calculated from LPI data. Structured to be used AFTER plot_data_pull, not with WITHIN plot_data_pull.

Description

Estimate annual & perennial canopy gaps from perennial canopy gaps and LPI cover data with a linear model built by Joe Brehm, to be published in McCord et al. (in prep as of 10/2023). All estimates require values for (1) the perennial gap window that matches the annual & perennial gap window to be estimated (e.g. to estimate annual gaps > 25 cm, use perennial gaps > 25 cm), (2) annual grass cover, (3) perennial grass cover, (4) shrub cover, and (5) forb cover. All cover variables should come from any-hit indicators calculated from LPI data. Structured to be used AFTER plot_data_pull, not with WITHIN plot_data_pull.

Usage

estimate_allgaps(gap_type = "25plus", perennial_gaps, AG, PG, SH, Forb)

Arguments

gap_type	Character indicating the gap window to be predicted. One of "25plus", "50plus", "100plus", or "200plus". Defaults to "25 plus".
perennial_gaps	Numeric vector containing the perennial gap values. Example indicator column name is "CP_percent_25plus".
AG	Numeric vector containing the any-hit annual grass cover values. Example indicator column name is "AH_AnnGrassCover".
PG	Numeric vector containing the any-hit perennial grass cover values. Example indicator column name is "AH_PerenGrassCover".
SH	Numeric vector containing the any-hit shrub cover values. Example indicator column name is "AH_ShrubCover".
Forb	Numeric vector containing the any-hit forb cover values. Example indicator column name is "AH_ForbCover".

Value

Numeric vector of estimated annual and perennial gap values for the descriptor indicated in gap_type
