This hypothetical expression set sampExpSet belongs to an ExpressionSet class. It contains 100 genomic features (probe_1 to probe_100) for 50 subjects (array_1 to array_50) and phenotype data of drugLevel, residualDisease, obsTime, obsCensor and strat. The expression values can be accessed by exprs(sampExprSet). The phenotype data can be accessed by pData(phenoData(sampExprSet))
这假想的表达的一套sampExpSet属于到ExpressionSet类。它包含100个基因50科目(array_1 array_50),和表型数据的drugLevel,residualDisease,obsTime,obsCensor和战略的特点(probe_1 probe_100)。可以访问由exprs(sampExprSet)表达式的值。表型数据可以访问由pData(phenoData(sampExprSet))
