[R] Transformations

[d.s91]

Hi, I'm having some trouble with R code for one of my assignment questions on
transforms. I've never used R for transformations so I'm not sure where to
being. Our prof did give us some partial R code.par(mfrow=c(2,2)) 
plot(X[,2],e) 
plot(X[,3],e) 
plot(X[,4],e) 
plot(X[,5],e) 

 Any help ?? 
3. Try the following transformations on the response variable: 
(a) ˜ y = ey 
(b) ˜ y = log(y) 
(c) ˜ y = 1/y 
(d) ˜ y = 1/y2 
(e) ˜ y = 1/√y 
Carry out the regression ˜ y = β0 + β1 x1 + β2 x2 + β3 x3 + β4 x4 + ϵ for
each case, 
including the residual analysis
