[R] differential equation

I'm trying to write differential equations into R code. Can anyone help me with the following equation:

(dy/dt) = v

(dv/dt) = y - y^3 + c(sin t)

where c is a constant. I've been using the "deriv()" function and it seems to work out the best, but I'm having trouble converting the above formula to R code.

Thank you,

Tim Sharac
