Bug in Half-normal function

[dslramsey]

I think there is a bug in the dHN.r code where you calculate the analytical integral for line transects. Currently it is

integral=pnorm(Xmax, 0, sigma)-0.5

However, I think the analytical integral should be

integral = 2*(pnorm(Xmax, 0, sigma)-0.5) * sqrt(pi/2) * sigma

I think the point transect one is OK

Thanks Dave.

Bug is now corrected in dHN.R
