Subject: Reading data for discriminant analysis
Dear R users,
I want to do discriminant analysis on my data. I have
successfully followed the discriminant analysis in V & R on
the iris data:
> ir <- rbind (iris3[,,1],iris3[,,2],iris3[,,3])
> ir.species <- c(rep("s",50),rep("c",50),rep("v",50))
> a <- lda(log(ir),ir.species)
> a$svd^2/sum(a$svd^2)
[1] 0.996498601 0.003501399
> a.x <- predict(a,log(ir),dimen=2)$x
> eqscplot (a.x,type="n",xlab="first linear discriminant", ylab = "second linear discriminant"
+ )
> text (a.x, ir.species)
I believe that the iris3 is rather special data format.
But I am unable to get a text file to become something like iris3.
I would like to be able to formulate my data into a useable format.
What is the proper procedure to create iris3 from external sources.
Thanks for your help,
Clayton Springer
