Subject: What the difference between .Golbalenv and package:base?
Dear rusers,
? ? As we know, there are a lot of environments in the search() path, such as?? .Golbalenv and package:base .
And ?i can just use ?.Golbalenv$a ,.Golbalenv$b to use the virable, ?but i must use as.envrionment("package:base") to find virable, i feel it not very convenient.
For example, when i use the following codes to add a new env into the search() path.
> tmp<-attach(NULL,name="new_name")
> assign("a",2,envir=as.environment("new_name"))
> a
[1] 2
> as.environment("new_name")$a
[1] 2
?I must always convert the name to the environment, How can i just use the following form:
> tmp<-attach(NULL,name="new_name")
> assign("a",2,envir=new_name) ? #like using ?.GlobalEnv
> a
[1] 2
> new_name$a
[1] 2
