This typically occurs while trying to read a delimited text file, often mistakenly labeled as a .csv but encoded as UTF-16 Unicode Text. This can be frustrating, especially if you're unsure about what went wrong.

In this guide, we'll explore the likely causes of this error and provide an effective solution to help you seamlessly read your data into R.

The Problem

When you attempt to read a text file into R using a command like:

If the file is actually encoded in UTF-16, you might receive the invalid multibyte string error. This indicates that R is struggling to interpret the byte sequences in the encoding of the file.

Causes of the Error

Incorrect file encoding: Reading a file with the wrong encoding can lead to misinterpreted characters and column names.

Embedded nulls: If the first line of data contains null characters, this will also trigger warnings and errors when attempting to read the file.

Solution: Fixing the Error

To successfully read a CSV file that is not encoded in a compatible format, you need to ensure that you specify the correct encoding. Here are step-by-step instructions to resolve the issue:

Step 1: Use the Correct Encoding

Step 2: Adjust Column Name Handling

Step 3: Test and Validate

After you adjust your function with the suggested encoding and parameters, re-run the command. If successful, you should be able to access your data without encountering the invalid multibyte string error.

Conclusion

Dealing with CSV files can often lead to frustrating issues, especially with encoding. However, by specifying the appropriate encoding and adjusting how R interprets your column names, you can efficiently solve the invalid multibyte string error.

With this knowledge in hand, you should be better equipped to manage your datasets and get the insights you need from your data analyses in R.
