Subsetting AnyHermesData Objects

Source: R/HermesData-methods.R
subset.Rd

[Stable]

This method subsets AnyHermesData objects, based on expressions involving the rowData columns and the colData columns.

Arguments

x

(AnyHermesData)
object to subset from.

subset

(expression)
logical expression based on the rowData columns to select genes.

select

(expression)
logical expression based on the colData columns to select samples.

Value

The subsetted AnyHermesData object.

Note

Note that this just inherits SummarizedExperiment::subset,SummarizedExperiment-method().
