Description

Finds either row or column maximum values of a matrix.

Usage

matMaxs(x, dim = 1)

Arguments

x

dim

=1, for row maximum values; =2, for column maximum values.

Value

Returns a numeric vector with row or column maximum values.

The function is very much the same as using apply(x, 1, max) or apply(x, 2, max), but faster.

Details

Matrix x may contain Inf or -Inf, but not NA or NaN.

Examples

# NOT RUN {
x = cbind(c(1:4,Inf), 5:1)
matMaxs(x)
matMaxs(x, 2)

# }
