toW4M

Exporting ExpressionSet instance into 3 tabulated files.

Description

The 3 .tsv files are written with the indicated file prefix, and '_dataMatrix.tsv', '_sampleMetadata.tsv', and '_variableMetadata.tsv' suffices, respectively. Note that the dataMatrix is transposed before export (e.g., the samples are written column wise in the 'dataMatrix.tsv' exported file).

Usage

toW4M(eset, ...)

## S4 method for signature 'ExpressionSet'
toW4M(eset, filePrefixC = paste0(getwd(), "/out_"), verboseL = TRUE, ...)

Arguments

`eset`	An S4 object of class `ExpressionSet` function.
`...`	Currently not used.
`filePrefixC`	Character: common prefix (including repository full path) of the three file names: for example, the 'c:/mydata/setname' value will result in writting the 'c:/mydata/setname_dataMatrix.tsv', 'c:/mydata/setname_sampleMetadata.tsv', and 'c:/mydata/setname_variableMetadata.tsv' files.
`verboseL`	Logical: should comments be printed?

Value

No object returned.
