graphics site
About six months ago there was a reference to a site (in french) that
did a spectacular job of demonstrating R's graphical capabilities.
My bookmarks were recently wiped and I cannot find this site despite my
best googling.
Anyone have the address which I have done a miserable job describing?
Thanks.

Inverse matrix using eigendecomposition
General goal: Write R code to find the inverse matrix of an nxn positive
definite symmetric matrix. Use solve() to verify your code works.
Started with a 3x3 matrix example to build the code, but something dosen't
seem to be working. I just don't know where I am going wrong.
##Example matrix I found online
A<-c(4,1,-1,1,2,1,-1,1,2)
m<-matrix(A,nrow=3,ncol=3)

boot.stepAIC fails with computed formula
I'm trying to use boot.stepAIC for feature selection; I need to be able to specify the name of the dependent variable programmatically, but this appear to fail:
In R-Studio with MS R Open 3.4:

boot.stepAIC fails with computed formula
Until I get a fix that works, a work-around would be to rename the 'y1' column, used a fixed formula, and rename it back afterwards.
Thanks for your help.

boot.stepAIC fails with computed formula
It seems that if you build the formula as a character string, and
postpone the "as.formula" into the lm call, it works.
instead of
frm1 <- as.formula(paste(trg,"~1"))
use
frm1a <- paste(trg,"~1")
and then
strt <- lm(as.formula(frm1a),dat)
regards,
Heinz
