When outputting to the console in Rstudio gives an error?

Question

R

When outputting the code to the console, it gives an error

Answer 1

You have not declared object n.
In the console, you can see that you put a sequence in the my_named_vector vector, but you didn’t put anything in n.
The fact that it is written in your script above does not say anything about the fact that it is in memory.
Moreover, in the upper right window in 'values' there are objects d, missed, my_named_vector, but there is no object n.
