errorMatrix

An error matrix reports the true/false potisitve/negative rates.

The R Analytic Tool To Learn Easily (Rattle) provides a
collection of utilities functions for the data scientist. This
package (v5.6.0) supports the companion graphical interface with
the aim to provide a simple and intuitive introduction to R
for data science, allowing a user to quickly load data from a CSV file
transform and explore the data, and to build and evaluate models.
A key aspect of the GUI is that all R commands are logged and
commented through the log tab.
This can be saved as a standalone R script file and as
an aid for the user to
learn R or to copy-and-paste directly into R itself. If you
want to use the older Rattle implementing the GUI in RGtk2
(which is no longer available from CRAN) then please install
the Rattle package v5.5.1.
See rattle.togaware.com for instructions on installing
the modern Rattle graphical user interface.
