Argument error; the number of columns does not equal the number of parameters.

This error typically occurs when the number of columns in a data frame or matrix does not match the number of parameters in a function call.

For example, if you have a data frame with 3 columns but you are trying to run a function that requires 4 parameters, you will get this error.

To fix this error, check the number of columns in your data frame or matrix and ensure that it matches the number of parameters required by the function. You may need to add or remove columns, or adjust the function call to match the data you have.
