Draws kernels of the best models.
figKernels(datares, age = 1, xlim = c(0, 50), ylim = c(0, 0.015), colors = c("#6b2934", "#4899c7", "#c8de86", "grey10"))
| datares | a data frame that contains the best models.  | 
    
|---|---|
| age | age of the seedling for which the figure is drawn (either 1 or 2).  | 
    
| xlim | numeric vectors of length 2, giving the x coordinates ranges.  | 
    
| ylim | numeric vectors of length 2, giving the y coordinates ranges.  | 
    
| colors | vector of colors.  |
