Question about picking a region

Hi there,

I have a question about selecting data over a geographical region. Suppose that data x(time,lat,lon) is with lat=(-90.0,90),lon=(-179.5,179.5) at 1x1 degree resolution. If I want to pick a region over the Pacific ocean, such as latitude from 30N to 30S, longitude from 150E to 120W. What I used is

latS = -30.0
latN = 30.0
lonL = 150.0
lonR = -120.0
y = x(time|:,{lat|latS:latN},{lon|lonL:lonR})

However, this will produce an area actually from 120W to 150E, instead of over Pacific. Does anyone know what shall I do to get it right? Thanks!

-Eddy
