QUESTION
I'm trying to mimic some of the dataframe functionality from R in C++, i.e., read from a CSV file into a matrix and add/remove rows. The number of rows in the CSV file can be anything, BUT the number of columns and their datatypes are fixed. So it's not supposed to be too general-purpose (i.e. variable number of columns or variable datatypes for columns). I've been able to make a basic program that reads data to a vector of string vectors.
...ANSWER
Answered 2017-Sep-22 at 14:23If each column is a different type, that implies you should have a vector of objects, not a vector of vectors. You're not dealing with tabular data, you're dealing with records.
