Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, : line 34 did not have 2 elements

This error message typically indicates a problem with the input data. The "scan" function is used to read data from a file or a connection, and the "line 34" in this case refers to the line number of the input file where the error occurred.

The error message suggests that the data on line 34 did not have exactly 2 elements, which could mean that there is a missing value, an extra delimiter, or some other issue with the formatting of the data.

To fix this error, you will need to check the input file and make sure that the data on line 34 (and other problematic lines) is properly formatted and contains the expected number of elements. You may also need to adjust the parameters of the "scan" function to match the format of your input data.
