generateRandom.Gene: Generates a random value from the defined function

In galgo: Genetic Algorithms for Multivariate Statistical Models from Large-Scale Functional Genomics Data

Description

Generates a random value from the defined function. The function used is stored in generateFunc value. The proper way to use this function is calling *mutate() method instead.

Usage

## S3 method for class 'Gene'
generateRandom(.O, n=1, ...)

Arguments

n	Number of random values.

Value

Returns random values.

Examples

   ge <- Gene(shape1=1, shape2=100)
   ge
   generateRandom(ge)
   generateRandom(ge)
   generateRandom(ge)

   # generation that depends on initial random selection ==> "is it silly?"
   ge$generateFunc = function(g, n=1, sh1, sh2) {
      if (is.null(g$value)) {
          g$value <- runif(n, sh1, sh2)
          g$value
      } else {
          g$value + runif(n, min=-10, max=10)
      }
   }
