[FORGED] Modifying the length of a matrix variable

Model4 <- brick("MaxPrecCCCMACanESM2rcp45.nc", var="onedaymax")
That is how Model4 is derived.?
When trying class(Model4), I receive:
[1] "RasterBrick"
attr(,"package")
[1] "raster"

Meanwhile, I will check on Google to see what I come up with in terms of your suggestion. :)

Yes, I reproduced the example above and it works just fine (and is what 
I want!!), but I cannot see why it does not work with my data, as it is 
a 3-dimensional array (latitude, longitude and time).

This is what comes from print(Model4):

3 variables (excluding dimension variables): double 
onedaymax[lon,lat,time] (Contiguous storage) units: mm/day double 
fivedaymax[lon,lat,time] (Contiguous storage) units: mm/day short 
Year[time] (Contiguous storage) 3 dimensions: time Size:95 lat Size:64 
units: degree North lon Size:128 units: degree East


I reviewed it over and over again, but I cannot see why this would not work?

Psigh!? Clearly Model4 is *not* an array!!!? It is an object of some 
"specialised" class (for which there is specialised print() method).? I 
have no idea what that class might be, but *you can tell.? What does

? ? class(Model4)

return?

Where did this "Model4" object come from?? What are you trying to *do*?

You might be able to get somewhere by searching (e.g. via Google) on
"subsetting objects of class melvin" where "melvin" is what is returned 
by "class(Model4)".

Doing

? ? str(Model4)

could be enlightening (but given your stubborn refusal to acquire 
insight into the workings of R, I am not optimistic).

This is not magic or religion.? You need to *understand* what you are 
dealing with, and proceed rationally.? Don't just hammer and hope.

cheers,
