Modified.TcCB.df

Artificial 1,2,3,4-Tetrachlorobenzene (TcCB) concentrations with censored values; 
 based on the reference area data stored in <code>EPA.94b.tccb.df</code>. The data 
 frame <code>EPA.94b.tccb.df</code> contains TcCB concentrations (ppb) in soil samples 
 at a reference area and a cleanup area. The data frame 
 <code>Modified.TcCB.df</code> contains a modified version of the data from the reference area. 
 For this data set, the concentrations of TcCB less than 0.5 ppb have been recoded as 
 <code>&lt;0.5</code>.

datasets

Graphical and statistical analyses of environmental data, with
focus on analyzing chemical concentrations and physical parameters, usually in
the context of mandated environmental monitoring. Major environmental
statistical methods found in the literature and regulatory guidance documents,
with extensive help that explains what these methods do, how to use them,
and where to find them in the literature. Numerous built-in data sets from
regulatory guidance documents and environmental statistics literature. Includes
scripts reproducing analyses presented in the book "EnvStats: An R Package for
Environmental Statistics" (Millard, 2013, Springer, ISBN 978-1-4614-8455-4,
<doi:10.1007/978-1-4614-8456-1>).
