[R] identical(length(x), 1) returns FALSE, but print(length(x)) is 1, length(x)==1 is TRUE, and is.integer(lenght(x)) is TRUE????

[Corrado]

Dear R,

the condition: 

identical(length(x),1) returns FALSE 

but

print(length(x))

returns 1 and:

is.vector(x) is TRUE.
is.integer(length(x)) is TRUE
length(x) ==1 is TRUE

I am puzzled.

Regards
