Estimate CPS backscatter in Echoview CSV files

Description

Estimate CPS backscatter in Echoview CSV files

Usage

extract_cps_nasc(
  path.in,
  pattern.in,
  path.out = path.in,
  suffix.out = "_nasc_cps.csv",
  x11.w = 1600,
  x11.h = 600,
  jpeg = TRUE,
  path.img = NULL,
  pattern.img = NULL,
  dist.bin = 2000,
  max.range = 350,
  transparency = 0.2,
  root = 1.5,
  scaling = 0.1,
  expansion = 2
)

Arguments

path.in	Directory containing CSV files.
pattern.in	Regular expression pattern used to list available CSV files.
path.out	Directory where outputs will be stored. Usually the same as path.in.
suffix.out	Suffix to append to resulting CSV file.
x11.w	Width of graphics window for line picks. Default = 1600 pixels.
x11.h	Height of graphics window for line picks. Default = 600 pixels.
jpeg	Save intermediate plots from line picks (TRUE/FALSE)?
path.img	Directory containing exported echogram images.
pattern.img	Regular expression pattern used to open corresponding echogram image.
dist.bin	Distance bin (m) for plotting results. Default is 2000 m, but should be made smaller for short transects.
max.range	Maximum depth range for bubble plots.
root	Constant for controlling bubble size. Default = 2 and should probably not be changed.
scaling	Constant for controlling bubble size. Default = 0.1 and should probably not be changed.
expansion	Constant for expanding axes in bubble plots.

Value

No objects are returned, but a new CSV file is produced along with several plots images showing the processing results.
