This question already has an answer here:

Declare variable with a dot at the begining in R [closed] (1 answer)

Create object

.object <- 2

Confirm object exists in global namespace

.object 
# [1] 2

yet

回答1:

Because variables starting with a . are hidden

If you do ls() you'll not find that object. From ?ls

all.names
a logical value. If TRUE, all object names are returned. If FALSE, names which begin with a . are omitted.

To get that name in the environment you need to do

ls(all.names = TRUE)

As the object is omitted it is not showing it in the workspace?
