A vector indicating subset of rows (and/or columns)
to operate over. If NULL, no subsetting is done.
which
An integer index in [1,K] ([1,N]) indicating which
order statistic to be returned.
dim.
An integervector of length two specifying the
dimension of x, also when not a matrix.
...
Not used.
Details
The implementation of rowOrderStats() is optimized for both
speed and memory.
To avoid coercing to doubles (and hence memory allocation), there
is a unique implementation for integer matrices.
Value
Returns a numericvector of length N (K).
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).
Author(s)
The native implementation of rowOrderStats() was adopted
by Henrik Bengtsson from Robert Gentleman's rowQ()
in the Biobase package.
