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.

Is your third variable on your 'Enhanced Scatter Plot' a control or an instrument? Thanks for the video!

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?

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.

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.

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.

Hi. Thank you for this video. I have one question: How can I get the R -squared value or other information about regression, for each regression line recognized trough a third variable with "car-scatterplot"? If I use summary(lm(y~x,data=mydata)) I have information about the whole selected dataset and not about each subgroup recognized trough "car-scatterplot" and a third variable. I hope the question is clear. Sorry, but I'm newbie of R.

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?
