Hello,
To plot a graph you don't need to compute the axis, R will do it for you:
# create data
set.seed(2020) # Make the results reproducible
x <- runif(100, 1000, 10000)
This is not very intuitive but the following will plot the x values in
the y axis, along the x axis values 1 to 100.
plot(x)
To plot a regression line you will need a regression model and that
means you need a response variable.
y <- x + rnorm(100)
model <- lm(y ~ x)
plot(x, y)
abline(model, col = "red")
The question is very basic, you should focus on learning a bit more of
R. Start with R-intro.pdf that comes with R. There are also many texts
online that cover this and lots of other graphics stuff.
Hope this helps,
Rui Barradas
