how do I plot a regression curve with the data?
I have a data set of 6 or so ordered pairs, and I've been able to graph
them and have decided to use a high-order polynomial regression. I've
used the following piece of code:
regression <- function(x,y) {
x <- c(insert_numbers_here)
y <- c(insert_other_numbers_here)
fit <- lm(y ~ x + I(x^2) + I(x^3) + I(x^4) + I(x^5) + I(x^6) +
I(x^7) + I(x^8) + I(x^9))
summary(fit)
This gives me the coefficients for the regression very nicely, but I
would like to plot both the data and the regression curve together. How
do I plot that regression curve as a fu...
