  3. Kinetic energy correlation in [R]

(https://en.wikipedia.org/wiki/R_(programming_language))

This thing posted below is wrong.If some plans to use OOP programming just because he read somewhere and thinks it is cool , it should abandon it very fast. This is my first(and last) class implemented in R. This is working :Kinetic correlation working

informationEnergy<-function(v)
{

frequencies=table(as.numeric(v))
prob=frequencies/length(v)
#from 21 to  28  is trash
#probreplace=c() 

#for( i in 1:length(v)){
#el=prob[as.character(v[i])]
#probreplace=c(probreplace,el)

#}

inf=sum(prob^2)

  return(new("energy",
          informationEnergy=inf,
          prob=prob))

}
oncoef=function(v,w)
{
i1=informationEnergy(v)
i2=informationEnergy(w)
informationEnergy1=i1@informationEnergy
informationEnergy2=i2@informationEnergy
#probabilities1=i1@prob
#probabilities2=i2@prob

probval1=c() 

for( i in 1:length(v)){
el=i1@prob[as.character(v[i])]
probval1=c(probval1,el)
}
probval2=c() 

for( i in 1:length(w)){
el=i2@prob[as.character(w[i])]
probval2=c(probval2,el)
}
N=probval1%*%probval2
N=as.numeric(N)

R=N/sqrt(i1@informationEnergy*i2@informationEnergy)
return(R)
}

setClass(Class="energy",
         representation(
            informationEnergy="numeric",
