 lin2 R Documentation

## Linear function defined from two planar points (x1,y1) and (x2,y2)

### Description

It gives the value of the linear function defined from two points (x1,y1) and (x2,y2) at any x

### Usage

```lin2(x1, y1, x2, y2, x)
```

### Arguments

 `x1` the x - abscissa of the first point `y1` the y - ordinate of the first point `x2` the x - abscissa of the second point `y2` the y - ordinate of the second point `x` the x - point where we compute the value of the linear function

### Value

It returns the value of the linear function from (x1,y1) to (x2,y2) at an arbitrary x.

### Note

The value of a linear function is built by this way for R to be faster than a two-vectors call.

### Author(s)

Demetris T. Christopoulos.

### Examples

```x1<-1
y1<-3
x2<-5
y2<-7
x<-10
ylin<-lin2(x1,y1,x2,y2,x)
print(ylin)
```
