Is there a command that can return all significant interaction terms in R?
For example:
Input = c(age, gender,nationality)
output = list of significant interactions = c(age * gender, gender * nationality, age * nationality * gender)
Try the broom
package:
library(broom)
m = lm(mpg ~ am * hp * disp, data = mtcars)
tidy.m = tidy(m)
tidy.m$term[tidy.m$p.value < 0.05]
Which gives you:
[1] "(Intercept)" "am" "am:disp" "am:hp:disp"
Is that what you want?
(This is assuming that the p value is the indicator of significance.)
