R: Calculate the x coordinates given a branch of dendrogram

cal_node_limit {dendsort}

R Documentation

Calculate the x coordinates given a branch of dendrogram

Description

cal_node_limit is a code modified from plotNodeLimit() to x coordinates of branches given a branch of dendrogram.

Usage

cal_node_limit(x1, x2, subtree, center)

Arguments

`x1`	A x coordinate`x1`
`x2`	Another x coordinate`x2`
`subtree`	A dendrogram object.`subtree`
`center`	A logical whether the dendrogram is centered.`center`

Value

output A list of parameters.

Examples

#generate sample data
set.seed(1234); par(mar=c(0,0,0,0))
x <- rnorm(10, mean=rep(1:5, each=2), sd=0.4)
y <- rnorm(10, mean=rep(c(1,2), each=5), sd=0.4)
dataFrame <- data.frame(x=x, y=y, row.names=c(1:10))
#calculate Euclidian distance
distxy <- dist(dataFrame)
#hierachical clustering "complete" linkage by default
hc <- hclust(distxy)

total <- cal_total_length(as.dendrogram(hc))
