[R] How to find points of intersection between harmonic function and a line

[FMH]

Hi,

Sorry for the very short explanation about the problem of intersection. 

I have a wave function monitored from the heart beat in a particular interval of 
times. Apart fom that, there is a line with positive slope (e.g: y = x+2) which 
lies across the wave and intersect on a number of points. My problem is i have 
no exact equation for such a complex harmonic wave produced by the heart pulse 
and so, cannot manage to find the intersection points. 


Therefore, i would be very grateful if someone could give some ideas or might 
suggest any packages in  R that can assist me to do so.

Thank you,
Fir

Sounds like second level school homework. If not, please explain your 
problem in more detail and
