我有一个data.frames的列表。我想知道如何删除列表中的data.frames，它们的名称是以下任意一个：c("out", "Name").
我试过r[names(r) != c("out", "Name")]没有成功。

r <- list(
     data.frame(Name = rep("Jacob", 6), 
               X = c(2,2,1,1,NA, NA), 
               Y = c(1,1,1,2,1,NA), 
               Z = rep(3, 6), 
             out = rep(1, 6)), 

 data.frame(Name = rep("Jon", 6), 
               X = c(1,NA,3,1,NA,NA), 
               Y = c(1,1,1,2,NA,NA), 
               Z = rep(2, 6), 
             out = rep(1, 6)), 

  data.frame(Name = rep("Jon", 6), 
                X = c(1,NA,3,1,NA,NA), 
                Y = c(1,1,1,2,2,NA), 
                Z = rep(2, 6), 
              out = rep(2, 6)), 

  data.frame(Name = rep("Jim", 6), 
                X = c(1,NA,3,1,NA,NA), 
                Y = c(1,1,1,2,2,NA), 
                Z = rep(2, 6), 
              out = rep(1, 6)))
