R help - Aug 2010 - Automated plot and linear regression line/data

Hi,

I have an excel sheet (already imported to R) with multiple columns and I am
looking for a way in R that will allow me to generate a plot for every
possible pair and its linear regression line/data.
 
Any tip/idea/script how do to so.

Thanks,
As hz

Hi,

I presume the easy way is using plot and lm.

Thx,

?pairs
?lattice::splom
?lattice::panel.xyplot


pairs( state.x77, panel=function(x,y){
	points(x,y)
	abline(lm(y~x), col='red')
})

library(lattice)
splom( ~state.x77, type=c('p','r') )
