Error on RStudio of the code "read.tree"

Hi everyone,

I import a RAxML tree file into the RStudio in the Galaxy.

  1. When I used the code: ```
    tree ← read.tree(treefile)
An error reported as: Warning message:
In read.tree(treefile) : no semicolon(s) [end(s) of tree] found

2. When I used the code:
 tree <- read.tree(file = "", text = NULL, tree.names = NULL, skip = 0, comment.char = "", keep.multi = FALSE)
In the console panel, that will appear a number like the screenshot as following.
![1737615805(1)|690x334](upload://aKMw1TFKCZFL18K9iKLEAh71B3x.png)

Can anyone help me?

Thank you.
