Create particle size distributions as particle counts and Qc sums for many VCT files

Description

Create particle size distributions as particle counts and Qc sums for many VCT files

Usage

create_PSD(
  vct_files,
  quantile,
  refracs,
  grid,
  log_base = NULL,
  max_boundary_proportion = NULL,
  ignore_dates = NULL,
  pop = NULL,
  use_data.table = TRUE,
  cores = 1
)

Arguments

vct_files	VCT files to grid.
quantile	OPP filtering quantile.
refracs	Dataframe of refractive indices to use for each population. Column names should be population names used in classification, values should be mid, lwr, upr.
grid	Named list of break points to use for gridding. Names should be fsc_small, pe, chl_small, Qc, diam.
log_base	If the break points are logged values, provide the base here to properly log the VCT data before gridding. If break points are not log use NULL.
max_boundary_proportion	Proportion of particles in each VCT file which can be removed as boundary points before discarding all data in the file. Should be > 0 and <= 1. If this parameter is NULL, no boundary points will be removed before gridding.
ignore_dates	Don't process VCT data with these dates.
pop	A single populations label to keep. Particles not matching this label will be ignored.
use_data.table	Use data.table for performance speedup, otherwise use dplyr.
cores	Number of cores to use

Value

Tibble of gridded data, grouped by date, fsc_small, pe, chl_small, Qc diam grid locations, and population. Each grid coordinate is an integer index into the corresponding grid breaks vector. The break point at that location defines the inclusive lower bound of the bin, and the next break point in the sequence defines the exclusive upper bound. Data columns summarizing each group are n for particle count and Qc_sum for the the sum of Qc.
