Hi, I hope the following code helps.
Best, Roland ## creating example data xx <- 1:30 yy <- 3 + 2*xx + rnorm(length(xx), mean=0, sd=2) plot(xx,yy) # looks reasonable ## the 'lm' mymodel <- lm(yy~xx) summary(mymodel) # just looking at the results ## extracting intercept and slope: coef(mymodel) intcp <- coef(mymodel)[1] slp <- coef(mymodel)[2] intcp slp > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Rainer M Krug > Sent: Friday, March 10, 2006 11:17 AM > To: [email protected] > Subject: [R] How to get the intercept from lm? > > Hi > > I am using R 2.2.0 under SuSE 10 > > I want to use lm() to get the slope and intercept for several > daatasets > and store them in a database.
