Julia Language Reading a DataFrame from a file Handling different comment comment marks
Example
Data sets often contain comments that explain the data format or contain the license and usage terms. You usually want to ignore these lines when you read in the DataFrame.
The readtable function assumes that comment lines begin with the '#' character. However, your file may use comment marks like % or //. To make sure that readtable handles these correctly, you can specify the comment mark as a keyword argument:
readtable("dataset.csv", allowcomments=true, commentmark='%')
