[R] Problem with retrieve.nc of clim.pact

[Pablo85]

Goodmorning to everyone,
I'm new so sorry for bad english and formulation.

I go to the point: I am using since months the retrieve.nc function from
clim.pact to extract data from netcdf files. I always had no problem, but
some days ago I updated both R and the package to the latest versione (don't
ask me what was the previous R version, cause I don't remember). 
However, now i am in serious trouble.
When i try opening the netcdf file, i use
a<-retrieve.nc(filename="/Users/P4blo/Desktop/DATA/Raw/Z500/Z500-1979-2010.nc",v.nam="hgt",t.rng=c(1,31))
just as was doing in the past.
but know, i obtain not more a 3D matrix but a 4D one!

[1] "dimensions 31 1 37 144"


but it is not over: the biggest problem is that if i try to plot the matrix,
i obtain a complete a completely fuzzy field, because i suppose that
somewhere the reading of the file was gone bad.
for instance, i use 

image.plot(a$dat[1,1,,]) 

has anyone a similar problem? 
thank you to everyone who will answer me.
