In arnejohannesholmin/cpplot3d: 3D-plotting and segmentation of sonar data

Extracts the variable (acoustic or segmentation) specified by 'var' from the 'data'. Only one time step must be given in 'data'.

Description

Extracts the variable (acoustic or segmentation) specified by 'var' from the 'data'. Only one time step must be given in 'data'.

Usage

cpplot3d.extract_var(data, var)

Arguments

data

is a list containing the data to plot, as returned from read.event(...,var=c("vbsc","voxels","ctd","beams","vessel","time")). May include school positions data$psxf, data$psyf and data$pszf. If non-school voxel probabilities are given in an array 'pr0s', or thresholded segmentation values 'sgsc'/'sgs0' are given, these can be plotted using the input 'var'.

var

is a string or a vector for two strings, specifying the variable to extract. If var[2] starts with "+" or "-", and the rest of the string is the four character name of a segmentation variable, the variable specified by var[1] is extracted but only ("+") or everything but ("-") the data in the segmentation mask. Adding a "-" at the end of var[2], so that this has 6 characters expands the subtraction to everythinb past the first segmentation index of the beam.
