rowRanges {matrixStats} | R Documentation |
Gets the range of values in each row (column) of a matrix.
rowRanges(x, na.rm=FALSE, ...) colRanges(x, na.rm=FALSE, ...) rowMins(x, na.rm=FALSE, ...) colMins(x, na.rm=FALSE, ...) rowMaxs(x, na.rm=FALSE, ...) colMaxs(x, na.rm=FALSE, ...)
x |
A numeric NxK matrix . |
na.rm |
If TRUE , NA s are excluded first, otherwise not. |
... |
Not used. |
The rowRanges()
function uses the much faster rowOrderStats
()
if there are no missing values.
rowRanges()
(colRanges()
) returns a
numeric
Nx2 (Kx2) matrix
.
rowMins()/rowMaxs()
(colMins()/colMaxs()
) returns a
numeric
vector
of length N (K).
