lin2 {inflection} | R Documentation |
It gives the value of the linear function defined from two points (x1,y1) and (x2,y2) at any x
lin2(x1, y1, x2, y2, x)
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 |
It returns the value of the linear function from (x1,y1) to (x2,y2) at an arbitrary x.
The value of a linear function is built by this way for R to be faster than a two-vectors call.
