| stage.vector.plot {popbio} | R Documentation |
Plots short-term dynamics and convergence to stage stage distribution using stage vector projections.
stage.vector.plot(stage.vectors, proportions=TRUE, legend.coords="topright",
ylim=NULL, xlab="Years", ylab=NULL, ... )
stage.vectors |
a matrix listing stage class vectors in columnw |
proportions |
plot proportional changes or total numbers, defaults to proportions. |
legend.coords |
a legend keyword or vector of x,y coordinates, defaults to top-right corner |
ylim |
the y limits of the plot, defaults to min and max values in stage.vector.projections |
xlab |
a label for the x axis |
ylab |
a label for the y axis |
... |
additional options are passed to plot function |
