npdrDistances2: npdrDistances2

In insilico/npdr: Nearest-neighbor Projected-Distance Regression

npdrDistances2

Description

Create m1 x m2 distance matrix between two datasets, (m1 instances and p attributes in dataset1 and m2 instances and p attributes in dataset2). Datasets should not include phenotype column. Uses function dist2 from flexclust. Used by nearestNeighbors2().

Usage

npdrDistances2(attr.mat1, attr.mat2, metric = "manhattan")

Arguments

attr.mat1	m1 x p matrix of m instances and p attributes
attr.mat2	m2 x p matrix of m instances and p attributes
metric	for distance matrix between instances (default: "manhattan", others include "euclidean", and for GWAS "allele-sharing-manhattan").

Value

matrix of m1 instances x m2 instances pairwise distances.

Examples

train_dat <- case.control.3sets$train
valid_dat <- case.control.3sets$validation

if (require("flexclust")) {
  dist.mat <- npdrDistances2(
    train_dat[, names(train_dat) != "class"],
    valid_dat[, names(valid_dat) != "class"],
    metric = "manhattan"
  )
}
