Graphical Data Analysis with R shows you what information you
can gain from graphical displays. The book focuses on why you draw
graphics to display data and which graphics to draw (and uses R to
do so). All the datasets are available in R or one of its packages and
the R code is available at rosuda.org/GDA.
Graphical data analysis is useful for data cleaning, exploring data
structure, detecting outliers and unusual groups, identifying trends
and clusters, spotting local patterns, evaluating modelling output,
and presenting results. This book guides you in choosing graphics
and understanding what information you can glean from them. It
can be used as a primary text in a graphical data analysis course
or as a supplement in a statistics course. Colour graphics are used
throughout.
