R中的多个数据帧为空

Question

How Can I null multiple data.frames? I can find my data.frames with this but am stuck to null them.

ls(pattern="pqr")

I usually did this to nullify any data.frame.

abc<-NULL
pqr<-NULL

You can assign NULL in a for loop. Try out:

for (i in seq_along(ls(pattern = "pqr"))){
        assign(ls(pattern = "pqr")[i], NULL)
}
