R Error in `partial()`:

`partial()` is a function from the `purrr` package in R that allows you to create a new function by partially applying arguments to an existing function. The error message you are seeing may be due to one of several reasons:

1. The `purrr` package may not be installed. You can install it using the command `install.packages("purrr")`.

2. The function you are trying to partially apply may not exist or may not be loaded into your R session.

3. You may have provided incorrect arguments to `partial()`. Make sure that the function you are trying to partially apply is the first argument to `partial()`, followed by the arguments that you want to partially apply.

4. There may be a syntax error in your code that is causing the error. Check that your code is properly formatted and that all parentheses, braces, and brackets are properly closed.

If none of these solutions work, please provide more information about your code and the specific error message you are seeing.
