Re: [R] add a linear regression line to the plot

2011-01-13 Thread ep

Hi, 

if it should be "lines" so you can do that

xy.lm <- lm(y~x)
lines(x, xy.lm$coeff[1] + x*xy.lm$coeff[2], col="blue", lwd=3)

Regards

ep

Re: [R] Exponential distribution

2011-03-22 Thread ep
Try this

x <- seq(0,15,0.01)
plot(x+1, dexp(x, 0.2), c(0,15), c(0,0.8),type="l", ylab="f(x)")
lines(x+1, dexp(x, 0.8))
grid()
abline(v=1, col="lightgray", lty="dotted",)

Best

You can use "Save history..." from the R-Console.
