R - I've got a DV with 2 IVs one of which has 5 levels. I tried using the "pequod" package; however found that it is not able to graph/simple slope a moderator with multiple levels. Is there a package available to do this? (data below)
dat$gpa <- as.factor(dat$gpa) mod1 <- lmres(item25 ~ psd * gpa, centered = c("psd", "gpa"), data = dat) sSlopes <- simpleSlope(mod1, pred = "psd", mod1 = "gpa") PlotSlope(sSlopes, namey = "Affirmative Action", namex = "Political Conservatism") structure(list(item25 = c(3L, 2L, 2L, 4L, 2L, 1L, 2L, 3L, 3L, 2L, 5L, 2L, 2L, 0L, 2L, 5L, 5L, 2L, 2L, 2L, 2L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 4L, 3L, 3L, 2L, 2L,
