Description

Plot populations values against species values. The objectif is to see the contribution of intra-specific vs inter-specific variation to trait gradient.

	plotSpPop(traits = NULL, ind.plot = NULL, sp = NULL, 
	col.ind = rgb(0.5, 0.5, 0.5, 0.5), col.pop = NULL, col.sp = NULL, 
	col.site = NULL, resume =  FALSE, p.val = 0.05, min.ind.signif = 10, 
	multipanel = TRUE, col.nonsignif.lm = rgb(0, 0, 0, 0.5), 
	col.signif.lm = rgb(1, 0.1, 0.1, 0.8), silent =  FALSE)

Arguments

traits

Individual Matrix of traits with traits in columns.

ind.plot

Factor defining the name of the plot in which the individual is.

sp

Factor defining the species which the individual belong to.

col.ind

Color for individual values.

col.pop

Color for populational mean values.

col.sp

Color for species mean values.

col.site

Color for sites mean values.

resume

Logical, if TRUE plot a simple form of the plot.

p.val

Choosen p.value to print significant linear relationship using linear model. Argument past to the lm funtion internally.

min.ind.signif

Minimum individual to print significant linear relationship.

multipanel

Logical value. If TRUE divides the device to shown several traits graphics in the same device.

col.nonsignif.lm

Color for non significant linear relationship.

col.signif.lm

Color for significant linear relationship.

silent

Logical value, if resume = FALSE do not print warning argument.

Details

Example of utilisation: Cornwell, W.K., Ackerly, D.D., 2009. Community assembly and shifts in plant trait distributions across an environmental gradient in coastal California. Ecological Monographs 79, 109-126.

Value

None; used for the side-effect of producing a plot.
