variables, but I want to also show the fit of the line on the graph as well.
I am using ggplot2 for other graphics in what I am working on, so even though
this would be a fairly easy thing to do in Excel, I would
Jim, you can use the function appended below, which is part of package

function(df = NULL, y = NULL, x = NULL,
method = lm, leg.loc = c(0, 0),
Hi:
Here's an example of how one might do this in a specific example using
geom_text().
# Some fake data:
df - data.frame(x = 1:10, y = 0.5 + (1:10) + rnorm(10))
# Fit a linear model to the data and save the model object:
mod - lm(y ~ x, data = df)
# Create a list of character strings - the
3 matches
