Very confusing R feature - completion of list item names

Question

I found a very suprising and unpleasant feature of R - it completes list item names!!! See the following code:

a <- list(cov_spring = \"spring\")
a$cov &l         


        

Answer 1

You can use [ or [[ instead.

a["cov"] will return a list with a NULL element. a[["cov"]] will return the NULL element directly.
