Form Row and Column Sums and Means
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 |
... |
Additional arguments, for use in specific methods. |
Value
See ?base::colSums
for the value returned by the
default methods.
