A euclidean distance function

Source: R/euc_dist.R

This function allows you to calculate the euclidean distance between two vectors

euc_dist(data, var1, var2)

Arguments

data

A data frame
var1

Numeric vector (generally f1).
var2

Numeric vectors (generally f2).

Examples

# Create some data
df <- data.frame(vowel = gl(n = 2, k = 5, labels = c('a', 'o')),
                 var1 = rnorm(10, 10, 2), 
                 var2 = rnorm(10, 20, 2))

# Calculate euc.dist on entire data frame
euc_dist(data = df, var1 = var1, var2 = var2)

#> [1] 30.38112

# Calculate euc.dist for each vowel
library(dplyr)
df %>%
 group_by(., vowel) %>%
 summarise(euc = euc_dist(., var1 = var1, var2 = var2))

#> # A tibble: 2 x 2
#>   vowel   euc
#>   <fct> <dbl>
#> 1 a      30.4
#> 2 o      30.4
