How might one implement data frame in R, Python, and other languages using C++?

A DataFrame is a data structure that organizes data into a 2-dimensional table of rows and columns, much like a spreadsheet. DataFrames are one of the most common data structures used in modern data analytics because they are a flexible and intuitive way of storing and working with data.
DataFrame Documentation / Code Samples. This is a C++ analytical library that provides interface and functionality similar to packages/libraries in Python and R. For example, you could compare this to Pandas or R data.
A data frame is the most common way of storing data in R and, generally, is the data structure most often used for data analyses. Under the hood, a data frame is a list of equal-length vectors. Each element of the list can be thought of as a column and the length of each element of the list is the number of rows.
We can create a dataframe in R by passing the variable a,b,c,d into the data. frame() function. We can R create dataframe and name the columns with name() and simply specify the name of the variables.
In general, data.frame solves a problem which is solved fundamentally differently in C++ (and other languages) – namely via class hierarchies, or, in the simplest case, via a vector of tuples.
Since you haven’t given specifics it’s hard to know what exactly you are after but if it’s ease of computation, Armadillo is a good linear algebra library for C++ (one among many). I haven’t yet found a good statistics framework for C++ – I suggest simply sticking with R for that.
