My interaction.plot is missing a data point

[sarahgrace]

#Two-way Interaction Plot

interaction.plot(x.factor = Group, trace.factor = Video,
response = ALI_Total, fun = mean,
type = "b", ylim=c(45,55),
xlab = "Group", ylab="ALI Score",
pch=c(1,19), col = c("black", "purple"))

My mean data point for "TrainingNonSTEM" will not show up and I am not sure why. If someone could please help me it would be greatly appreciated!

Hi, and welcome!

Please see the FAQ: What's a reproducible example (`reprex`) and how do I do one? Using a reprex, complete with representative data will attract quicker and more answers.

For this type of problems, screenshots are seldom helpful, and if it takes too long to reverse engineer the problem, peeps are unlikely to attempt a cure. Usually, the big problem is the data. It doesn't have to be all the data, or even your data, a built in data set like mtcars that just illustrates the problem is fine.
