vpr_roi_concentration: Calculate VPR concentrations

In vprr: Processing and Visualization of Video Plankton Recorder Data

Calculate VPR concentrations

Description

Calculates concentrations for each named taxa in dataframe

Usage

vpr_roi_concentration(
  data,
  taxas_list,
  station_of_interest,
  binSize,
  imageVolume
)

Arguments

data	a VPR dataframe as produced by vpr_ctdroi_merge
taxas_list	a list of character strings representing taxa present in the station being processed
station_of_interest	The station being processed
binSize	passed to bin_calculate, determines size of depth bins over which data is averaged
imageVolume	the volume of VPR images used for calculating concentrations (mm^3)

Examples

data('ctd_roi_merge')
ctd_roi_merge$time_hr <- ctd_roi_merge$time_ms /3.6e+06

taxas_list <- c('Calanus', 'krill')
binSize <- 5
station_of_interest <- 'test'
imageVolume <- 83663

taxa_conc_n <- vpr_roi_concentration(ctd_roi_merge, taxas_list,
station_of_interest, binSize, imageVolume)
