This tutorial shows how to make a scatterplot in R. We also add a regression line to the graph. We also make a scatterplot with a third variable to add extra insight into our graph.

Great video, but I am trying to do just this, had the same code you used. R didnt return any errors, but my regression line does not show up on my scatterplot. Any help on why that is would be appreciated.

I keep getting these errors when I plot 2 independent ad one dependent variable. How do I fix it??? ## Warning in scatterplot.default(X[, 2], X[, 1], groups = X[, 3], xlab = xlab, : number of groups exceeds number of available colors ## colors are recycled

Please I am working with several subsets of data, can I get an explanation on what to do. The question goes like this, for birth weights and pregnancy, I should assign women who smoke to 1, those who don't to 2, and those who never tried to 3. Them I should later plot a graph of the birth weight in addition to the pregnancy of those who didn't, thus 2.

Hey! Thank you very much for your useful video. I was just wonderin though: somehow I have made it such that my plots appear in a new window (i.e not in the console). Every plot I do, it makes a new window that minimises when I change my code. How do I change it bac so that my plots appear only in the plot section of the console?

Please make more videos on R. I am a psychologist who likes your simple and easy method of teaching stats with R. Please also cover non linear models, ancova, manova, repeated measures etc in your future videos. But using the same easy method. Great stuff.

is it necessary to specify the data source in the abline function? I tried with specifying it and without it and the same regression line still plots the same either way.

thank you so much sir but can you show us how to calculate the p-value to see if this reverse correlation is significant enough?
