Dear R Helpers, I have a fairly complicated list of data frames. To give you an idea of the structure, the top of the str output is shown below. How do I refer to the data.frame name for each data.frame in the list? That is, how can I pull the terms Advertising2007, AirFreightDelivery2007, Apparel2007 etc. out of the list? I need them to keep track of correlations that I am doing inside each data frame of the list. Apologies for not sending a reproducible example. I am hoping that someone knows this off the top of their head. --John Sparks
