The error message suggests ls.im is a list; your script would be easier to understand (for me) if you used ls.im = list(x1=janb3,...,x10=decb4) If ls.im is a list, you need to pass ls.im[[i]] to crop, which is a list element (a raster), whereas ls.im[i] is a list (with one element).

I tried few things but no luck. Any help would be highly appreciated.
