I think you can do all you want using the functionality in the raster package. E.g. you can read the ncdf file into R as a raster brick, which is fairly easy to work with. Something the this might work:
require(raster);require(ncdf) # Assuming that the variable name is slp b <- brick(slp.mon.mean.nc, varname = 'slp') # now you can plot any of the time step using: plot(raster(b, layer = 1))# time step one But there might be several other ways to do what you want.
