## Constructor:
parameterSet(n.comp = 1, center.cols = c(TRUE), scale.cols = c(FALSE),
center.rows = c(FALSE), scale.rows = c(FALSE), simultaneous = c(FALSE),
alg.typ = "parallel", fun = "logcosh", alpha = 1,
maxit = 200, tol = 1e-04, w.init = NULL, max.attempts = 3, verbose = FALSE)

## S4 method for signature 'ParameterSet'
getParamSetCount(object)

## S4 method for signature 'ParameterSet'
getOneParamSet(object, j)

## S4 method for signature 'ParameterSet'
getAllParamSets(object)

## S4 method for signature 'ParameterSet'
reseedParamSets(object, new.seeds = NULL)

Details

When creating a DexBatch object, a ParameterSet may be supplied (in the params slot) in order to specify a range of parameter values to test. Each slot in ParameterSet may accept either a single value or a range of values. If multiple slots have multiple values, the ParameterSet will encompass each possible combination of individual slot values.

Any slot values not specified during object construction are given their default values (see constructor), e.g., calling parameterSet() results in a ParameterSet with a single set of parameter values. The getParamSetCount method returns the total number of parameter sets defined in a ParameterSet.
