A descriptive analysis of a given data set is typically the first part of statistical modeling and evaluation of data. In the following, we will show how the functions that come with XploRe can be used for this purpose.
All routines for descriptive analysis that we present are part of the libraries xplore (basic routines) and stats (basic statistical methods). We will not use graphical methods here. Tools for the graphical exploration of data are extensively discussed in Chapter 3.
Before proceeding to the next section, please type
library("xplore") library("stats")to load the libraries xplore and stats . Note also that we use
setenv("outputstringformat","%s")throughout this section. This command suppresses the quotation marks in text output.
