get.node.info: Get the information for specified node
In IPCAPS: Iterative Pruning to Capture Population Structure

Description Usage Arguments Value Examples

Obtain the information for specified node from the output list of ipcaps.

1	get.node.info(cluster.obj, node)

`cluster.obj`	A list returned from the `ipcaps` function.
`node`	An integer representing a node number to enquire information as shown in the HTML output files.

The return value is NULL if node's information does not exist or a list containing PCs, eigen.fit, index, and label as explained below:

$PCs is a matrix of pricipal components of this node.
$eigen.fit is a number represeting the EigenFit value of this node.
$index is a vector of row number (individuals) of raw.data (input data).
$label is the vector of labels of all individuals that belongs to this node.

# Importantly, bed file, bim file, and fam file are required
# Use the example files embedded in the package

BED.file <- system.file("extdata","ipcaps_example.bed",package="IPCAPS")
LABEL.file <- system.file("extdata","ipcaps_example_individuals.txt.gz",package="IPCAPS")

my.cluster <- ipcaps(bed=BED.file,label.file=LABEL.file,lab.col=2,out=tempdir())

#Here, to obtain the information of specified node, for example, node 3
node.info <- get.node.info(my.cluster,3)
ls(node.info)
