R help - Jul 2008 - graphing regression coefficients and standard errors

Hello,
        I am interested in plotting my regression analysis
results(regression coefficients and standard errors obtained through OLS and
Tobit models)
in the form of graphs.What is the best way to accomplish this? Thanks.

Hi Murali,

The plot function works on an "lm" object. The example from the help
page of
lm.

Ritwik

ctl <- c(4.17,5.58,5.18,6.11,4.50,4.61,5.17,4.53,5.33,5.14)
trt <- c(4.81,4.17,4.41,3.59,5.87,3.83,6.03,4.89,4.32,4.69)
group <- gl(2,10,20, labels=c("Ctl","Trt"))
weight <- c(ctl, trt)
anova(lm.D9 <- lm(weight ~ group))
summary(lm.D90 <- lm(weight ~ group - 1))# omitting intercept
summary(resid(lm.D9) - resid(lm.D90)) #- residuals almost identical

opar <- par(mfrow = c(2,2), oma = c(0, 0, 1.1, 0))
plot(lm.D9, las = 1)      # Residuals, Fitted, ...

plot(obj$lm) will give you a set of diagnostic plots. What you seem to be
after is ?termplot. Also look at John Fox's effects package and at Frank
Harrell's Design package (sub functions ols and plot.Design).

Regards, Mark.
