plotN: Plot Numbers at Age

Description

Plot scape model predicted numbers at age.

Usage

plotN(model, what="d", years=NULL, ages=NULL, axes=TRUE,
      same.limits=TRUE, div=1, log.transform=FALSE, base.log=10,
      main="", xlab="", ylab="", cex.main=1.2, cex.lab=1, cex.strip=0.8,
      cex.axis=0.8, las=what == "b", tck=c(1,what=="b")/2,
      tick.number=10, lty.grid=3, col.grid="white", pch=16,
      cex.points=1, col.points="black", ratio.bars=3, col.bars="grey",
      plot.it=TRUE, ...)

Arguments

model

fitted scape model.

what

what should be plotted: "d"[efault], "i"[nitial year], "r"[ecruitment], "y"[ear panels], "b"[ubble plot].

years

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

ages

vector of numbers indicating which ages should be plotted (all by default).

axes

whether axis values should be plotted.

same.limits

whether panels should have same y-axis limits.

div

denominator to shorten values on y axis.

log.transform

whether values should be log-transformed.

base.log

logarithm base.

main

main title.

xlab

x-axis label.

ylab

y-axis label.

cex.main

size of main title.

cex.lab

size of axis labels.

cex.strip

size of strip 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.

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 is a combination of "i"[nitial year] and "r"[ecruitment].

Examples

plotN(x.cod, div=1000, xlab=c("Age (years)","Year"),
      ylab=c("Individuals (million)","One-year-olds (million)"))

plotN(x.cod, "b", xlab="Age (years)", ylab="Year", cex.points=0.7)

plotN(x.cod, "y", div=1000, ages=3:10, xlim=c(2,11), xlab="Age",
      ylab="Individuals (million)", cex.strip=0.7, cex.axis=0.7,
      tck=0.5)
