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))
