map border problem (projection "Van der Grinten")

[José María Michia]

Hello. I'm new to the GMT. I am reading the documentation and I have a
little problem.

I'm playing with the manual examples of psbasemap. I'm tring "Van der
Grinten" projection.

At first, I wanted to find a way to generate annotations on the two
axes, not only the latitude. For this I modified the parameter-R:

psbasemap -R0/360/-80/80 -JV180/7i -Bg30a30/g30a30

Sinusoidal projection work fine too:

psbasemap -R0/360/-80/80 -Ji0/0.02i -Bg30a30/g30a30

Thanks for your attention.
