simple multivariate linear model plot
...users,
I am trying to get a simple plot for a linear model. The following function does the job
of getting all the plots of the lm function but the "main" plot.
multivarplot <-
function(...){
x1 <- rnorm(10); x2 <- rnorm(10); x3 <- rnorm(10)
y <- rnorm(10)
multivarfit <- lm(y ~ x1 + x2 + x3)
par(mfrow = c(3,2))
plot.lm(multivarfit)
}
where the "main" plot is graph of the variable (fitted : x1 + x2 + x3 ) against y.
This is similar to the graph in Phil Spector's book (intro to the S and Splus) p. 227.
It seems to be a very simple task...
