Importing a CSV file
In this exercise, you will import the file sample.csv using both read.csv() and fread() to compare these functions. Here are the contents of this file:
id,"name",val
29192,"Robert Whitaker", 200
49301 ,"Elisa Waters,190
The values in the file are separated by a comma. Note the unwanted spaces between entries, and the imbalanced quote in the second row.
