colSums: Form Row and Column Sums and Means

In BiocGenerics: S4 generic functions used in 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 methods.

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 ?base::colSums for a description of these arguments.
...	Additional arguments, for use in specific methods.

Value

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