This error message indicates that there is an issue with the input data or the encoding of the data. The function `make.names` is trying to create unique column names for a data frame based on the input column names, but it is encountering an invalid multibyte string in one of the column names.
To resolve this error, you could try the following steps:
1. Check the encoding of your input data. You can use the `Encoding()` function to check the encoding of a character vector or data frame column.
2. If the encoding is not correct, try converting the data to a different encoding using the `iconv()` function.
3. If the encoding is correct, check the input data for any special characters or non-ASCII characters that might be causing the issue. You can use the `grep()` function to search for specific patterns in the data.
4. Once you identify the problematic column name or character, you can either remove it or replace it with a valid character using the `gsub()` function.
5. Finally, try running the `make.names()` function again with the updated input data.
