Hello all, So I am using the (formula entry) method for randomForests:
randomForest(y~x1+x2+...+x39+x40,data=xxx,...) but the issue is that some of the items in that package dont take a formula entry - you have to explicitly state the y and x vector: randomForest(x=xxx[,c('x1','x2',...,'x40')],y=xxx[,'y'],...) Now my question is whether there is a function/way to tell R to take a formula and make the two corresponding datasets [x,y] (that way I dont have to create the x dataset manually with all 40 variables I have). There must be a more elegant way to do this than x=xxx[,c('x1','x2',...,'x40')] Thanks!
