[R] Help with vectorization

Hi every one. I have a exponential function (3 fitting parameters) that I
would like to use to produce data (6 series) without having to use a loop.
Here

wl = seq(300,500,1)

k1 = c(1.2e-6, 4.9e-6, 9.6e-6, 2.7e-10, 6.7e-8, 7.44e-6)
k2 = c(726, 352, 128, 5232, 1538, 128)
k3 = c(-176, -224, -257, 88.7, -111, -256)

stations = c('R5d', 'R5a', 'R9', '108', '406', '409')


phiDIC = k1[1]*exp(k2[1]/(wl+k3[1])) #Here I would like to vectorize this
function to create my 6 series instead of having to loop.


Regards,
Phil
