plot.choicealpha {ClustGeo} R Documentation

## Plot to choose the mixing parameter

### Description

Plot two curves of explained inertia (one for D0 and one for D1) calculated with choicealpha.

### Usage

## S3 method for class 'choicealpha'
plot(
x,
norm = FALSE,
lty = 1:2,
pch = c(8, 16),
type = c("b", "b"),
col = 1:2,
xlab = "alpha",
ylab = NULL,
legend = NULL,
cex = 1,
...
)


### Arguments

 x an object of class choicealpha. norm if TRUE, the normalized explained inertia are plotted. Otherwise, the explained inertia are plotted. lty a vector of size 2 with the line types of the two curves. See par pch a vector of size 2 specifying the symbol for the points of the two curves. See par type a vector of size 2 specifying the type of lines of the two curves. See par col a vector of size 2 specifying the colors the two curves. See par xlab the title fot the x axis. ylab the title fot the y axis. legend a vector of size two the the text for the legend of the two curves. cex text size in the legend. ... further arguments passed to or from other methods.

### Examples

data(estuary)
D0 <- dist(estuary$dat) D1 <- as.dist(estuary$D.geo) # the geographic distances between the cities
range.alpha <- seq(0,1,0.1)
K <- 5
cr <- choicealpha(D0,D1,range.alpha,K,graph=FALSE)
plot(cr,cex=0.8,norm=FALSE,cex.lab=0.8,ylab="pev",
col=3:4,legend=c("socio-demo","geo"), xlab="mixing parameter")
plot(cr,cex=0.8,norm=TRUE,cex.lab=0.8,ylab="pev",
col=5:6,pch=5:6,legend=c("socio-demo","geo"), xlab="mixing parameter")
