echoIBM.oneping.oneschool(data, esnm = NULL, TVG.exp = 2,
  compensated = c("pitch", "roll"), calibrate = TRUE, noise = c("nr",
  "bg", "ex"), max.memory = 1e+09, dumpfile = "dump.txt", ask = FALSE,
  parlist = list(), msg = FALSE)

Arguments

data

see below.

esnm

is the name of the echo sounder. Currently implemented are "MS70", "ME70", "EK60", "MS70_circular" (may be given in lover case)

TVG.exp

is the exponent of the eamotric spreading of the sound wave, theoretically 2 for Sv and 4 for TS.

compensated

specifies which rotations are compensated for by the echo sounder. Legal values are "pitch" and "roll", which are both compensated for in the MS70 sonar.

calibrate

is FALSE if calibration data are to be discarded if present.

noise

is a vector of character strings of length 2, specifying which types of noise to apply to the data:

max.memory

is the maximum amount of memory to allow for the function to occupy. The level of for loops is chosen according to this value, i.e. if the method using only two loops, one for the radial distances and one for the unique frequencies, demands more memory than 'max.memory', the method usint three for loops is chosen.

dumpfile

is the name of the file to which information and warnings about the simulation is written.

ask

is TRUE if the used should be asked to for approval if the memory of the least memory demanding calculation method of the individual radial sampling intervals exceed the memory limit 'max.memory'.

parlist

is a list of input parameters to the function echoIBM.add.noise(), which generates noise and randomness. See echoIBM.add.noise() for explaination of the possible variables.

data

is the list of input parameters giving the information about the school consisting of 'Nl' fish.

Dynamic

variables NA
