Dealing with empty and incomplete lines

When reading irregular files, i.e., files with varying/missing fields in rows, fread() tries to parse them intelligently. However, it may not be always possible to guess if the irregular lines should be skipped or imported by filling missing fields. For such cases, you can use the fill argument of fread().

You will be importing the following file:

id,name,val
9002019291929192,Robert Whitaker,
9200129401349301 ,Elisa Waters,190  
9200149429834456 , Karla Schmidt

Notice that the first and last lines are incomplete.

Import the sample.csv file using fread() without any additional arguments. Notice the warning it generates.
