In Franvgls/NeAtlIBTS: R Library for the Northeastern Atlantic & NS IBTS Surveys

Function gearPlotHHNS.wgdp plots Wing Spread vs. Depth behaviour including the NS

Description

Produces a WingSpread vs. DoorSpread plot and a model with nls R function. Data are taken directly from DATRAS using function getHHdata from library(icesDatras) It only produces plots for surveys with HH files uploaded in DATRAS If there are two different sweeps in the data, produces a model for each sweep length.

Usage

gearPlotHHNS.wgdp(
  Survey = "NS-IBTS",
  years,
  quarter,
  country,
  c.inta = 0.8,
  c.intb = 0.3,
  col1 = "darkblue",
  col2 = "steelblue2",
  getICES = T,
  pF = T
)

Arguments

Survey:	either the Survey to be downloaded from DATRAS (see details), or a data frame with the HH information with the DATRAS HH format and the years and quarter selected in years and quarter
years:	years to be downloaded and used, had to be available in DATRAS. The time series will be ploted in grey dots, last year in steelblue2, it depends on the order of years, not the actual chronological year.
quarter:	the quarter of the survey to be ploted
country:	The country chosen to be plotted (checks if it's available in the HH file)
c.inta:	the confidence interval to be used in the confint function for long sweeps and for sweeps if there is only one length
c.intb:	the confidence interval to be used in the confint function for short sweeps if there are two
col1:	color for the symbols and lines for the whole set if only one set of sweeps are used, and for the data from the long set of sweeps.
col2:	color for the symbols and lines for the data from the short sweeps in case there are two.
getICES:	Should the data be downloaded from DATRAS? If T, default, the data are taken from DATRAS through the icesDatras package.
pF:	if set to F takes out the points and leaves only the lines in the graphs

Details

Surveys available in DATRAS: i.e. SWC-IBTS, ROCKALL, NIGFS, IE-IGFS, SP-PORC, FR-CGFS, EVHOE, SP-NORTH, PT-IBTS and SP-ARSA

Value

Produces a graph with WingSpread vs. Depth. it also includes information on the ship, the time series used, the models and parameters estimated.
