当我在R studio中附加data.frame时,我收到以下消息:
以下物体被掩盖......
我忘了分离data.frame
data<-read.table(file.choose(),header=TRUE)
View(data)
attach(data)
## The following objects are masked from vih (pos = 3):
## edad, edadg, id, numpares, numparg, sifprev, udvp, vih
## The following objects are masked from vih (pos = 4):
## edad, edadg, id, numpares, numparg, sifprev, udvp, vihhere

有没有办法知道哪些data.frames附加?
有没有办法用一个命令或函数分离所有data.frames?
