NNS.norm: NNS Normalization

In NNS: Nonlinear Nonparametric Statistics

NNS Normalization

Description

Normalizes a matrix of variables based on nonlinear scaling normalization method.

Usage

NNS.norm(X, linear = FALSE, chart.type = NULL, location = "topleft")

Arguments

X	a numeric matrix or data frame, or a list.
linear	logical; FALSE (default) Performs a linear scaling normalization, resulting in equal means for all variables.
chart.type	options: ("l", "b"); NULL (default). Set (chart.type = "l") for line, (chart.type = "b") for boxplot.
location	Sets the legend location within the plot, per the x and y co-ordinates used in base graphics legend.

Value

Returns a data.frame of normalized values.

Note

Unequal vectors provided in a list will only generate linear=TRUE normalized values.

Examples

## Not run: 
set.seed(123)
x <- rnorm(100) ; y<-rnorm(100)
A <- cbind(x, y)
NNS.norm(A)

### Normalize list of unequal vector lengths

vec1 <- c(1, 2, 3, 4, 5, 6, 7)
vec2 <- c(10, 20, 30, 40, 50, 60)
vec3 <- c(0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3)

vec_list <- list(vec1, vec2, vec3)
NNS.norm(vec_list)
