I don't usually do much with graphs in R, and this is my first time adding a line of best fit. Hopefully this is an easy problem to solve.
I'm looking at a variable called soloKills along the range 5:28. Here are all my commands, in script form: range=5:28 graph=soloKills title="Solo kill/death data" xlabel="Number of deaths/1 game" ylabel="Mean number of kills/1 game" #No problems with the scatterplot plot(x=range, y=graph, main=title, xlab=xlabel, ylab=ylabel, ylim=c(0,20)) abline(lm(range~graph)) I checked several websites, the abline(lm(/x-variable/~/y-variable/)) format *should* work. But here is what happens: http://r.789695.n4.nabble.com/file/n3693567/Regression_problem.png The line is obviously far too steep. I can guarantee there are no outliers in soloKills to throw it off: > soloKills [1] 9.040472 10.184595 11.201935 12.130823 13.583477 14.098845 14.489703 [8] 15.329752 15.562500 15.884757 16.239704 16.513289 16.383912 16.547543 [15] 16.823374 17.051370 17.027644 17.300562 17.641723 17.702673 18.436170 [22] 18.783562 19.274419 21.373832 Can anyone help me fix the regression line?
