Scale a vector

From every element in a vector, subtract center and divide by scale.

scale_vector(y, center = mean, scale = sd)

Arguments

y	A numeric vector.
center	Either a function that computes center of data (such as mean) or a single numeric value.
scale	Either a function that computes variability of data (such as sd) or a single numeric value.

Value

The same object as y just with every element scaled

Examples

y <- 1:10
scale_vector(y)
#>  [1] -1.4863011 -1.1560120 -0.8257228 -0.4954337 -0.1651446  0.1651446
#>  [7]  0.4954337  0.8257228  1.1560120  1.4863011

scale_vector(y, center = median, scale = IQR)
#>  [1] -1.0000000 -0.7777778 -0.5555556 -0.3333333 -0.1111111  0.1111111
#>  [7]  0.3333333  0.5555556  0.7777778  1.0000000

scale_vector(y, center = 10, scale = 2)
#>  [1] -4.5 -4.0 -3.5 -3.0 -2.5 -2.0 -1.5 -1.0 -0.5  0.0
