ABC {Xeva} | R Documentation

## area between curves Computes the area between two time-volume curves.

### Description

area between curves Computes the area between two time-volume curves.

### Usage

    ABC(contr.time = NULL, contr.volume = NULL, treat.time = NULL,
      treat.volume = NULL)

### Arguments

`contr.time` | Time vector for control.
`contr.volume` | Volume vector for control.
`treat.time` | Time vector for treatment.
`treat.volume` | Volume vector for treatment.

### Value

Returns batch response object.

### Examples

    contr.time <- treat.time  <- c(0, 3, 7, 11, 18, 22, 26, 30, 32, 35)
    contr.volume<- contr.time * tan(60*pi/180)
    treat.volume<- treat.time * tan(15*pi/180)
    abc <- ABC(contr.time, contr.volume, treat.time, treat.volume)
    par(pty="s")
    xylimit <- range(c(contr.time, contr.volume, treat.time, treat.volume))
    plot(contr.time, contr.volume, type = "b", xlim = xylimit, ylim = xylimit)
    lines(treat.time, treat.volume, type = "b")
    polygon(c(treat.time, rev(treat.time)), c(contr.volume, rev(treat.volume)),
            col = "#fa9fb5", border = NA)
