[R-sig-Geo] Plotting median values globally

[Bede-Fazekas Ákos]

Hello,
It is because the wrong place of the closing bracket. This might work, 
since margin, at, cuts etc. are the parameters of levelplot(9 not raster():
levelplot(raster(RCP1pctCO2Median,61), 
margin=F,at=cutpoints,cuts=11,pretty=TRUE,par.settings=mapTheme, 
main="Median values")
HTH,

I already first created a raster stack, called "RCP1pctCO2median", which contains the median values to be plotted. However, what I would like to do is simply plot only those values at Year 61 for each grid cell. There are 138 layers, with each layer representing one year. The idea would be to plot only those values for Year/layer 61 globally (i,e, for each grid cell), but I am unsure how to isolate that specific year/layer?

This is what I have so far, but all that this does is plot 138 mini plots, and I just want one plot showing the median values (i.e. Year 61):
