# 16.4 Data analysis

There are some basic data analysis functions implemented in radare. The most basic one is just a memory parser that tries to identify pointers to flags, strings, linked lists, handled endianness with 'cfg.bigendian' and displays integer values of contained dwords and strings. Here's a simple example from a basic debugger session to analyze the stack to get information about pointers.
