scape (version 1.0-4)

plotB: Plot Biomass, Recruitment, and Landings

Description

Plot scape model predicted biomass, stock recruitment, and landings.

Usage

plotB(model, what="d", series=NULL, years=NULL, axes=TRUE, div=1,
      legend="bottom", main="", xlab="", ylab="", cex.main=1.2,
      cex.legend=1, cex.lab=1, cex.axis=0.8, las=1,
      tck=c(1,what=="d")/2, tick.number=5, lty.grid=3, col.grid="white",
      pch=16, cex.points=0.8, col.points="black", lty.lines=1:3,
      lwd.lines=2, col.lines="black", ratio.bars=3, col.bars="grey",
      plot.it=TRUE, ...)

Arguments

model

fitted scape model.

what

what should be plotted: "d"[efault], "s"[tock recruitment], or "l"[andings].

series

vector of strings indicating which column names in model$B data frame should be plotted (all by default).

years

vector of numbers indicating which years should be included (all by default).

axes

whether axis values should be plotted.

div

denominator to shorten values on y axis, or a vector with two elements referring to x and y axis.

legend

legend location: "bottom", "left", "top", "right", or "" to suppress legend.

main

main title.

xlab

x-axis label.

ylab

y-axis label.

cex.main

size of main title.

cex.legend

size of legend text.

cex.lab

size of axis labels.

cex.axis

size of tick labels.

las

orientation of tick labels: 0=parallel, 1=horizontal, 2=perpendicular, 3=vertical.

tck

tick mark length.

tick.number

number of tick marks.

lty.grid

line type of gridlines.

col.grid

colour of gridlines.

pch

symbol for points.

cex.points

size of points.

col.points

colour of points.

lty.lines

line type of main lines, possibly a vector.

lwd.lines

line width of main lines, possibly a vector.

col.lines

colour of main lines, possibly a vector.

ratio.bars

width of bars.

col.bars

colour of bars.

plot.it

whether to draw plot.

...

passed to xyplot.

Value

• When plot.it=TRUE, a trellis plot is drawn and a data frame is returned, containing the data used for plotting. When plot.it=FALSE, a trellis object is returned.

concept

Fisheries stock assessment

Details

The "d"[efault] plot shows spawning biomass and vulnerable biomass as lines, and landings as bars, on the same scale.
