precip_slr() will produce estimates of mean annual precipitation and standard error
using leaf area analysis.
precip_slr(
data,
regression = "Peppe2018",
slope = NULL,
constant = NULL,
error = NULL
)A table with MAP estimates for each site
A data frame that must include the columns "morphotype", "leaf_area", and "specimen_number". Must be species level data.
A string representing one of the following pre-loaded regressions:
"Peppe2018" - for global precipitation estimates
"Peppe2011" - The Americas, Japan, and Oceania
"Jacobs2002" - Africa
"Wilf1998" - The Americas and Africa
Slope, if using a custom regression
Constant, if using a custom regression
Standard error, if using a custom regression
