Description

Container for high-throughput assays and experimental metadata. SnpSet class is derived from eSet, and requires matrices call, callProbability as assay data members.

Extends

Directly extends class eSet.

Creating Objects

new('SnpSet', phenoData = [AnnotatedDataFrame], experimentData = [MIAME], annotation = [character], protocolData = [AnnotatedDataFrame], call = [matrix], callProbability = [matrix], ...)

SnpSet instances are usually created through new("SnpSet", ...). Usually the arguments to new include call (a matrix of genotypic calls, with features (SNPs) corresponding to rows and samples to columns), phenoData, experimentData, annotation, and protocolData. phenoData, experimentData, annotation and protocolData can be missing, in which case they are assigned default values.

Slots

Inherited from eSet:

assayData:

Contains matrices with equal dimensions, and with column number equal to nrow(phenoData). assayData must contain a matrix call with rows representing features (e.g., SNPs) and columns representing samples, and a matrix callProbability describing the certainty of the call. The content of call and callProbability are not enforced by the class. Additional matrices of identical size may also be included in assayData. Class:AssayData-class

Methods

Class-specific methods:

snpCall(SnpSet), snpCall(SnpSet,matrix)<-

Access and set elements named call in the AssayData slot.

exprs(SnpSet), exprs(SnpSet,matrix)<-

Synonym for snpCall.

snpCallProbability(SnpSet), snpCallProbability<-(SnpSet,matrix)<-

Access and set elements named callProbability in the AssayData slot.

Derived from eSet:

updateObject(object, ..., verbose=FALSE)

Update instance to current version, if necessary. See updateObject and eSet

isCurrent(object)

Determine whether version of object is current. See isCurrent

isVersioned(object)

Determine whether object contains a 'version' string describing its structure . See isVersioned

Standard generic methods:

initialize(SnpSet):

Object instantiation, used by new; not to be called directly by the user.

validObject(SnpSet):

Validity-checking method, ensuring that call and callProbability is a member of assayData. checkValidity(SnpSet) imposes this validity check, and the validity checks of eSet.
