Examples

# Sample two random ultrasound profiles from the default dataset
x <- mosaic::sample(mpm.us, 1, replace = FALSE, prob = NULL)
x <- as.matrix(dichotomize(x[, 2:15]))
y <- mosaic::sample(mpm.us, 1, replace = FALSE, prob = NULL)
y <- as.matrix(dichotomize(y[, 2:15]))

# Compute the euclidean distance
r <- jaccard(x, y)
print(r)
