I am trying to load a phylogenetic tree from TimeTree as a Newick file into R. I downloaded the file from TimeTree onto my laptop and attempted to "load workspace" into R, but it came up with this error.

What am I doing wrong, and how do I load my file into R? Thanks in advance.

> load("~/Downloads/Schiedea_species.nwk")
