cal_node_limit: Calculate the x coordinates given a branch of dendrogram

In dendsort: Modular Leaf Ordering Methods for Dendrogram Nodes

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 coordinatex1
x2	Another x coordinatex2
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))
