In this blog post I will continue with arrays in communicating cross-platform via DLLs.

In this blog post I will continue with arrays in communicating cross-platform via DLLs.

In this blog post I will start to describe the data structures and the use of pointers in communicating cross-platform via DLLs.

Lists allows us to keep a collection of various objects together

Vectors and matrices are designed to hold single types. When we need to mix data types in a tabular form we can use a data frame.

Factors are like vectors but with values classed into levels. When vectors have a limited number of repeated values they fit the bill.

Adding Captions to matrices make them more readable and allows us to retain information when we subset the matrix.

Often we have the need to arrange data in a structure with rows and columns, or we need to represent a collection of vectors. R has a built-in matrix type th...

Expanding on our Vectors Basics we will continue with operations accross vectors.

Expanding on the basics of the simple data classes in Part 1: The Console and Variables, we now start with the first higher dimension construct: vectors
