Add markeredges in seaborn lmplot?
As per the comment from @Sören, you can add the markeredges with the keyword scatter_kws. For example scatter_kws={'linewidths':1,'edgecolor':'k'}
sns.lmplot(x="size", y="tip", data=tips)
gives a scatter plot. By default the markers have no edges. 
How can I add markeredges? Sometimes I prefer to use edges transparent facecolor. Especially with dense data. However, 
Neither markeredgewidth nor mew nor linewidths are accepted as keywords.
Does anyone know how to add edges to the markers?
