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 -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
