%3.3 Even with base graphics or Excel we never really plot the data itself, we only create a representation; ggplot2 makes this distinction explicit.
production rules of a grammar grammars that produce a language consisting of afamily of graphs production rules that substitute parts of a graph with other parts (gluing) aninitial graphas starting point edge and vertex labelsby terminal and non-terminal symbols …
Making a graphic elegant and clear is the work of the designer, the purpose of the grammar is to insure that the graphic is tied to data, and to separate graphics that make sense from graphics that are non-sense. I’m not ggplot2′s creator, Hadley Wickham, but I do find myself in discussions trying to explain how to build graphs in ggplot2.
����VA��. /Subtype /Image /Length 7 0 R In R‘s base graphics or in Excel, you feed ranges of data to a plot as x and y elements, then manipulate colors, scale dimensions and other parts of the graph as graphical elements or options.
Demonstration of the key concepts in the grammar of graphics: data, geometries, aesthetic mappings and scale mappings. In addition, ggplot2′s structure makes it very easy to tweak a graph to look the way you want by adding mappings.

"Destined to become a landmark in statistical graphics, this book provides a formal description of graphics, particularly static graphics, playing much the same role for graphics as probability theory played for statistics." #,x�`+��?�\�a��&˰i�ʟ�S��WݐK�cX�O�1��;����cAa�&�s��J����eу��"D+Ԓ���A�qqr�)xz���y��� eu�����p�����W���Kk�b 21 Mar 2014. . /BitsPerComponent 1 Four color throughout.

You feed ggplot2 your data, then apply a series of mappings and transformations to create a visual representation of that data. Mthtl Sp 6 The graphics code was roughly one and a half megabytes in size. Posted on March 28, 2014 by Thomas Hopper in R bloggers | 0 Comments, “The emphasis in ggplot2 is reducing the amount of thinking time by making it easier to go from the plot in your brain to the plot on the page.” (Wickham, 2012), “Base graphics are good for drawing pictures; ggplot2 graphics are good for understanding the data.” (Wickham, 2012). It’s a very elegant system, but also very different from other graphing systems.
