Run the regression tree analysis with specified number of splits

Description

run.regression.tree This function is the main regression tree function

Usage

run_regression_tree(
  LF,
  fcol,
  lcol,
  bins,
  Nsplit,
  save_dir,
  manual = FALSE,
  select = NA,
  lat.min = 1,
  lon.min = 1,
  year.min = 1,
  quarter = TRUE,
  year = FALSE,
  include_dummy = FALSE,
  pdf = FALSE,
  lf_scale = 1.5
)

Arguments

LF	The length frequency data frame input; must include four columns: lat, lon, year, and quarter
fcol	The first column in the data frame with length frequency info
lcol	The last column in the data frame with length frequency info
bins	Names of all bins included in LF
Nsplit	The number of splits
save_dir	The directory where results will be saved
manual	Whether to use user-specified splits; default = FALSE
select	User-specified splits; default = NA
lat.min	Minimal number of lat grids allowed for a cell, which could not be split beyond that
lon.min	Minimal number of lon grids allowed for a cell, which could not be split beyond that
year.min	Minimal number of years allowed for a cell, which could not be split beyond that
quarter	Whether to consider quarter as a splitting dimension; default = TRUE
year	Whether to consider year as a splitting dimension; default = FALSE
include_dummy	Whether to include dummy data; default = FALSE
pdf	Whether to save figures in pdf - default is in png
lf_scale	scale mean lf plot

Value

return the input LF with cell number and the percentage of total LF variance explained by each split
