loops over regression models
...uite a while, and I know I can use foreach to build a loop to
condense the codes (especially if I have a large number of models to
run).
In Stata, it would be something like:
****************************************************
// read in data
use kidiq, clear
// run two regression
reg kid_score mom_hs
reg kid_score mom_iq
// the next three lines are equivalent of the previous two lines
foreach var in mom_hs mom_iq {
reg kid_score `var'
}
***************************************************
So I want to figure out how to use R to do this. Below are my codes:

plotting a function with given formula in ggplot2
...tion (something
that curve() does in the standard R plotting). I did some search and
found that stat_function() can be used for this. But somehow it is not
working. The following is my code. Can you please tell me where I am
going wrong and what the correct code would be:
reg1 <- lm(kid_score ~ mom_hs, data=iqdata)
scatter <- ggplot() + geom_point(data=iqdata,
aes(x=as.factor(mom_hs), y=kid_score) )
+ xlab("Mother's High School Status")
+ ylab("Children's Test Score")...
