indx: Index-finding in a Sorted Vector

Description

For each of given values, indx finds the index of the value in a vector sorted in ascending order that the given value is barely greater than or equal to.

Usage

indx(x, v)

Arguments

x

vector of numeric values, the indices of which are to be found.

v

vector of numeric values sorted in ascending order.

Value

Returns a vector of integers, that are indices of x-values in vector v.

Details

For each x[i], the function returns integer j such that $$v_j \le x_i < v_{j+1}$$ where \(v_0 = - \infty \mathrm{ and } v_{n+1} = \infty\).

Examples

# NOT RUN {
indx(0:6,c(1:5,5))
indx(sort(rnorm(5)),-2:2)

# }
