Data frames *are* lists. They just have a guaranteed structure and a different class, but they may be used interchangably with lists nearly everywhere.
Try class(ByEBNum) for a more relevant check of what kind of object you have.

I obviously don't know what I'm doing. I want to create "ByEBNum" as a data frame, but it comes out as a list. How do I make it a data frame? > EBNumStn <- c(673.65, 800, 1000, 1000, 800, 700, 600, 500, 400, 200, 50, 50 ) > ByEBNum <- data.frame(c(1:12),EBNumStn) > typeof(EBNumStn) [1] "double" > typeof(c(1:12)) [1] "integer" > typeof(ByEBNum) [1] "list" > ByEBNum c.1.12.
