file	GlobalMinimization.C
	Example based in http://cran.r-project.org/web/packages/DEoptim/DEoptim.pdf Please install the R package DEoptim before run this example.
file	Integration.C
	Numerical integration using R passing the function from ROOT.
file	Interpolation.C
	More Information for R interpolation in http://stat.ethz.ch/R-manual/R-patched/library/stats/html/approxfun.html NOTE: this example illustrates an interpolation with random points given from ROOT and procedures made in R's environment.
file	Minimization.C
	Example based in http://root.cern.ch/root/html/tutorials/fit/NumericalMinimization.C.html http://stat.ethz.ch/R-manual/R-devel/library/stats/html/optim.html.
file	SimpleFitting.C
	Create an exponential fitting The idea is to create a set of numbers x,y with the function x^3 and some noise from ROOT, fit the function to get the exponent (which must be near 3) and plot the points with noise, the known function and the fitted function.
