### Usage

    comp.uri(tv, x)

### Arguments

`tv` | A vector of two numeric values, t and v. Both t and v are in [0,1]

### Examples

    x <- seq(1, 10, by=1)
    tv <- c(0.1, 0.5)

    # opposite order
    y1 <- seq(10, 1, by=-1)
    o1 <- order(y1)
    x.o1 <- x[o1]

    comp.uri(tv, x.o1)

    # same order
    y2 <- seq(1, 10, by=1)
    o2 <- order(y2)
    x.o2 <- x[o2]

    comp.uri(tv, x.o2)
