How to formulate quadratic function with interaction terms for the PLS fitting model?

I have two ideas about it.
1-
i) Entering variables in quadratic form is done with the command I
(variable ^ 2) -
plsr (octane ~ NIR + I (nir ^ 2), ncomp = 10, data = gasTrain, validation =
"LOO"
You could also use a new variable NIR_sq <- (NIR) ^ 2
ii) To insert a square variable, use syntax I (x ^ 2) - it is very
important to insert I before the parentheses.
iii) If you want to make the interaction betwee...

Quadratic function with interaction terms for the PLS fitting model?

...tting a linear model, I want to fit my
data with a quadratic function with interaction terms. But I am not sure
how. I will use an example to illustrate my problem:
Following the example in the PLS manual:
## Read data
data(gasoline)
gasTrain <- gasoline[1:50,]
## Perform PLS
gas1 <- plsr(octane ~ NIR, ncomp = 10, data = gasTrain, validation = "LOO")
where octane ~ NIR is the model that this example is fitting with.
NIR is a collective of variables, i.e. NIR spectra consists of 401 diffuse
reflectance measurements from 900 to 1700 nm.
Instead of fitting with predict.octane[i]...

R for Irix 6.5 or lower

Good Day:
Has anyone successfully compiled R, especially R.1.1.1, for Irix 6.5 or
lower (an SGI octane machine) and if so, may I get a copy of it? Our
computer does not have all the requisite software for compiling R -- to wit,
a fortran compiler -- and there is insufficient demand here for R to warrant
purchasing a compiler from SGI. I am trying to spur demand for R here by
making it more availa...

extract the initramfs from a kernel

Hello,
is there a way to extract an initramfs from a running kernel?
and from a kernel lying on a disk?
If yes, how?

skeleton for initramfs archive

Is there a skeleton for an initramfs, like mkinitrd do for an initrd?
An archive where all I could need for my initramfs could be present, with a
shell script ready to fill in with my work to be done.
Thanks
