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
