scape (version 1.0-4)

plotLA: Plot Length at Age

Description

Plot scape model fit to length-at-age data.

Usage

plotLA(model, together=FALSE, sex=NULL, axes=TRUE, same.limits=TRUE,
       between=list(x=axes,y=axes), ylim=NULL, bands=1, main="",
       xlab="", ylab="", cex.main=1.2, cex.lab=1, cex.strip=0.8,
       cex.axis=0.8, las=1, tck=0, tick.number=5, lty.grid=3,
       col.grid="grey", pch=16, cex.points=0.5, col.points="black",
       lty.lines=1, lwd.lines=4, col.lines=c("red","blue"),
       lty.bands=2*(!together), lwd.bands=1, col.bands="black",
       plot.it=TRUE, ...)

Arguments

model

fitted scape model containing element LA.

together

whether both sexes should be plotted in one panel.

sex

string indicating which sex should be plotted (both by default).

axes

whether axis values should be plotted.

same.limits

whether panels should have same y-axis limits.

between

list with x and y indicating panel spacing.

ylim

vector with lower and upper y-axis limits.

bands

extent of error bands relative to standard error.

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, possibly a vector where element 2 refers to males.

cex.points

size of points, possibly a vector where element 2 refers to males.

col.points

colour of points, possibly a vector where element 2 refers to males.

lty.lines

line type of main lines, possibly a vector where element 2 refers to males.

lwd.lines

line width of main lines, possibly a vector where element 2 refers to males.

col.lines

colour of main lines, possibly a vector where element 2 refers to males.

lty.bands

line type of error bands.

lwd.bands

line width of error bands.

col.bands

colour of error bands, possibly a vector where element 2 refers to males.

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.

Examples

plotLA(x.oreo, xlab="Age", ylab="Length (cm)")

mykey <- list(text=list(lab=c("Female","Male")), space="right",
              lines=list(lwd=4,col=c("red","blue")))
plotLA(x.oreo, together=TRUE, xlab="Age", ylab="Length (cm)", pch=NA,
       key=mykey)

mykey <- list(text=list(lab=c("Female","Male")), space="right",
              points=list(pch=16,cex=0.5,col=c("red","blue")))
plotLA(x.oreo, together=TRUE, xlab="Age", ylab="Length (cm)",
       col.points=c("red","blue"), lty.lines=0, key=mykey)
