dist_cosine {svs}

Compute Cosine Distances

Description

A function for computing cosine distances.

Usage

dist_cosine(x, diag = FALSE, upper = FALSE)

dist_cos(x, diag = FALSE, upper = FALSE)

Arguments

x

A numeric matrix (containing coordinates).

diag

Logical specifying whether the diagonal of the resulting distance matrix should be printed.

upper

Logical specifying whether the upper triangle of the resulting distance matrix should be printed.

Details

The cosine distance equals 1 - the cosine similarity.

Value

A distance matrix.

Examples

SndT_Fra <- read.table(system.file("extdata", "SndT_Fra.txt", package = "svs"),
   header = TRUE, sep = "\t", quote = "\"", encoding = "UTF-8",
   stringsAsFactors = FALSE)
lsa.SndT_Fra <- fast_lsa(SndT_Fra)
dist_cosine(lsa.SndT_Fra$pos1[, 1:7])
