matrix-summary: Form Row and Column Sums and Means

In nturaga/BiocGenerics: S4 generic functions for Bioconductor

Description

Form row and column sums and means for rectangular objects..

NOTE: This man page is for the rowSums, colSums, rowMeans, and colMeans S4 generic functions defined in the BiocGenerics package. See ?base::colSums for the default methods (defined in the base package). Bioconductor packages can define specific methods for objects (typically array-like) not supported by the default method.

Usage

     colSums (x, na.rm = FALSE, dims = 1)
     rowSums (x, na.rm = FALSE, dims = 1)
     colMeans(x, na.rm = FALSE, dims = 1)
     rowMeans(x, na.rm = FALSE, dims = 1)

Arguments

x	a rectangular object, like a matrix or data frame
na.rm, dims	see colSums

Value

See ?base::colSums for the value returned by the default methods.

Specific methods defined in Bioconductor packages will typically return an object of the same class as the input object.
