IPMpack (version 2.1)

addPdfGrowthPic: Adds probability density functions of density function of size or increment given current size and growth to plots.

Description

Function generates pdfs (probability density functions) corresponding to chosen sizes and adds them to a figure using growth methods.

Usage

addPdfGrowthPic(respType = "sizeNext", sizesPlotAt = c(20, 50, 60), sizeRange = c(20, 400), incrRange = c(-10, 50),  scalar = 100, growthObjList, cols = 1:5, cov = data.frame(covariate=1), minShow = 1e-2, jitt = 2,   ...)

Arguments

respType

character string identifying the response variable for the growthModelComp. wither "sizeNext", "logincr" or "incr". Defaults to sizeNext.

sizesPlotAt

vector, list of sizes at which pdfs should be plotted.

sizeRange

sizeRange for which pdf should be estimated

incrRange

increment range for which pdf should be estimated

scalar

value by which pdf may be multiplied to improve visibility

growthObjList

list of growth objects for which pdfs are desired to be plotted

cols

colours corresponding to the list of growth objects for plotting

cov

a data-frame with one row containing all covariates other than size related covariates; defaults to 1; will be ignored if no covariates are fitted

minShow

minimum value below which pdf lines will not be shown (to avoid ugly vertical lines)

jitt

amount by which sequential pdfs should be separated on the x axis, for visibility

...

extra arguments to pass to the plot function.

Value

none

Examples

# Data with size and sizeNext
dff <- generateData()

a1 <- growthModelComp(dff, makePlot = TRUE)
addPdfGrowthPic(respType = "sizeNext", 
	sizesPlotAt = c(2, 6, 10), scalar = 1, jitt = 0.1, 
		sizeRange = c(-5, 25), 
			growthObjList = a1$growthObjects, cols = 2:5)
