How do I draw a straight line on plot using R?
r, scatter-plot
Solution
You need to use function `abline`:
abline(a=-1.331, b=2.522)
Argument `a` is the intercept and argument `b` the slope. See `?abline` for more details.
Problem
I would like to draw a straight line on plot using the following linear equation. ``` y = 2.522x-1.331 ``` I used the following code to get a scatterplot. ``` data=read.csv("C://book.csv") plot(data$x,data$y) ```
