Remove the `add=TRUE` or calculate the values manually and you'll see
that the function value is zero because the values in `d` are too big
compared to `m` (where the function peak is). Compare your result to the
following:
plot(
function(d) k*exp(-0.5*(d-m)^2/sd^2),
xlim = m + 3*sd * c(-1,+1)
)
Your parameters don't quite fit the observed values.
