[R] Creating vectors

[JesperHybel]

You can use following script....I think



#create a vector of random numbers on which to test script

v<-sample(1:3,size=90,replace=TRUE)

#creates two matrixes out of vector v which can be assigned to M to test
script
M2<-matrix(v,ncol=2)
M3<-matrix(v,ncol=3)

M<-   #Assign you're matrix or a testmatrix to M and run script



result<-numeric()
imaks<-length(M[,1])
jmaks<-length(unique(M)[,1])

for (i in 1:imaks){

for (j in 1:jmaks){
if (sum(M[i,]==unique(M)[j,])==length(M[1,]))  {
result[i]<-j
}
}
}

result




## The script uses loops so its not efficient - in other words its slow and
might be too slow for larger matrixes.
