[FLR-list] problem to create a FLStock object

[Iago Mosqueira]

Hi,

I am afraid some material is in need of review.

Please try this:

# Create an empty FLQuant but of the right size, change values below

flq <- FLQuant(NA, dimnames=list(year=1980:2010, age=1:10))

# Now the FLStock will get the dimensions from this FLQuant

sol <- FLStock(flq)

# or if you have loaded on it the data for, for example, catch.n

sol <- FLStock(catch.n = flq)


> sol <- FLStock(iniFLQuant=sol)

but iniFLQuant is not a named slot in FLStock

Best,


Iago
