[R] Problem with reproducing log likelihood estimated with ghyp package

Thank you very much for your answer.

I did not think about the scale influencing the log likelihood score. The
first simulation was zero mean student t distributed variables with
variance=v/(v-2). And as far as I can understand, that is exactly what
dt(x,v) assumes. This also gave me the same result as the ghyp package. 
Scaling the variance to get t distributed variables with variance=5^2 gave a
totally different likelihood score for the reason you mentioned.
