rowOrderStats: Gets an order statistic for each row (column) in a matrix
Description
Gets an order statistic for each row (column) in a matrix.Usage
rowOrderStats(x, which, dim.=dim(x), ...)
colOrderStats(x, which, dim.=dim(x), ...)
Arguments
which
An integer
index in [1,K] ([1,N]) indicating which
order statistic to be returned. Missing values
This method does not handle missing values, that is, the result
corresponds to having na.rm=FALSE
(if such an argument would
be available).Details
The implementation of rowOrderStats()
is optimized for both
speed and memory.
To avoid coercing to double
s (and hence memory allocation), there
is a unique implementation for integer
matrices.See Also

in colSums
