如何在图的名称中使用列表名称？

Question

I have created several list enviroments. Then I wrote a function to draw several figures from the stored data and I would like to use a list name as a part of figure name.

list_xName <- list(aa = 1:10, bb = exp(-3:6), cc=-3:6)  
drawL<-function(list_xName){
plot(list_xName$aa,list_xName$bb)
savePlot(filename=paste("fig_",xxxxxxx,sep=""),type="eps")  
}  

Instead of 'xxxxxxx' in savePlot I would like to have a name of the list.

I hope that my question is understandeble enough. Thank you in advance.
