CFS_freq: frequency distributions by geo-location per species

Description

frequency distributions by geo-location per species

Usage

CFS_freq(
  tr_meta,
  freq.label_data = "",
  freq.uid_level = "uid_radius",
  freq.cutoff_year = -999,
  freq.geo_resolution = NULL
)

Value

a data table of counts of uid by latitude-longitude per species

Arguments

tr_meta

meta table from function CFS_format()

freq.label_data

description of tr_meta

freq.uid_level

which uid level to count(uid_project, uid_site, uid_tree, uid_meas, uid_sample, uid_radius)

freq.cutoff_year

cut-off year for a subset which series were recorded on or after

freq.geo_resolution

resolution of longitude and latitude in degree, default: c(5,5)

Examples

# treated ring measurement
dt.samples_trt <- readRDS(system.file("extdata", "dt.samples_trt.rds", package = "growthTrendR"))
# Compute frequency statistics at radius level
dt.freq <- CFS_freq(
  dt.samples_trt$tr_all_wide,
  freq.label_data = "demo-samples",
  freq.uid_level  = "uid_radius"
)
class(dt.freq)
