normalize: Normalize/standardize the columns of a matrix
In SVMMaj: Implementation of the SVM-Maj Algorithm

Description Usage Arguments Value Author(s) References See Also Examples

Standardize the columns of an attribute matrix X to zscores, to the range [0 1] or a prespecified scale.

1	normalize(x, standardize = "zscore")

`x`	An attribute variable which will be scaled.
`standardize`	Either a string value denoting a predefined scaling, or a list with values `a` and `b` corresponding with the numeric centering and scaling, that is, using the function `x * standardize$b - standardize$a`.

The standardized matrix. The numeric centering and scalings used are returned as attribute "standardize".

## standardize the first 50 objects to zscores
x  <- iris$Sepal.Length
x1 <- normalize(x[1:50], standardize = 'zscore')
## use the same settings to apply to the next 100 observations
x2 <- normalize(x[-(1:50)], standardize = attr(x1, 'standardization'))
