classify_site function

Classify inventory data based on site index

Use the site variable to classify a forest management data.

classify_site(df, site, nc = 3, plot, .groups = NA)

Arguments

• df: A data frame.
• site: Quoted name for the site variable.
• nc: number of categories used to classify the data. If 3, a additional column will be created with levels Lower, Middle and Upper, referencing the 3 categories. If not, only numbers will be used to differentiate the categories. Default: 3.
• plot: Quoted name for the plot variable.
• .groups: Optional argument. Quoted name(s) of grouping variables used to fit multiple regressions, one for each level of the provided variable(s). Default NA.

Returns

A data frame classified based on the site index.

Examples

library(forestmangr)
data("exfm17")
head(exfm17)

# Classify data into 3 classes:
ex_class <- classify_site(exfm17, "S", 3, "plot")
head(ex_class ,15)
