HTSet

S4 class for storing high through-put experiment data. It has three enssential components, the edata, fdata, and pdata. The edata is the expression/abundance matrix of each feature in each sample. The features are in rows and samples are in columns. The fdata is the feature data which holds the information for each feature, such as gene names, protein IDs, or metabolite names. The pdata is the phenotype data that describe additional information for each sample, such as sex, condition, or treatment. The rows in the edata must match the rows in the fdata, and the columns in the edata must match the rows in the pdata.

Slots

matrix. Must be numeric (integer or float)

fdata

data.frame. The number of rows and row names must match those of the edata.

pdata

data.frame. The number of rows and row names must match the number of columns and column names of edata.

assay

list. Additional assay or study information.
