Matrix and vector multiplication

matvect it is a helper function to multiply matrices with vector by rows or columns

matvect(df, x, by = "row")

Arguments

df	Numeric Data-frame or matrix.
x	Numeric vector.
by	Character, with two value "row" or "col"

Value

data-frame

Note

This function multiplies matrices with vectors by rows or colums. If by = "row" all values of each row will be multiplied with each value of the vector x. If by = "col" all values of each column will be multiplied with each value of the vector x.

Examples

if (FALSE) {
# Do not run
data(net)
veh <- age_ldv(net$ldv[1:4], agemax = 4)
matvect(veh, 1:4)
}
