asDataFrame: Check that input data is a data.frame
In made4: Multivariate analysis of microarray data using ADE4

Description Usage Arguments Details Value Note Author(s) See Also

This function is called by isDataFrame which converts input data into a data.frame suitable for analysis in ADE4. This function is not normally called by the user

1	asDataFrame(indata)

indata

A matrix, data.frame, ExpressionSet or marrayRaw-class or RangedSummarizedExperiment, SummarizedExperiment. If the input is gene expression data in a matrix or data.frame. The rows and columns are expected to contain the variables (genes) and cases (array samples) respectively.

bga and other functions in made4 call this function and it is generally not necessary to call this directly. isDataFrame calls isDataFrame, and will accept a matrix,data.frame, ExpressionSet or marrayRaw-class, SummarizedExperiment,RangedSummarizedExperiment format. It will also transpose data or add a integer to generate a positive data matrix. If the input data contains NA, these must first be removed or imputed (see the R libraries impute() or pamr()).

Returns a data.frame suitable for analysis by ade4 or made4 functions.

This is not normally called by a user. Internal function.
