## Marginal Effects function
TwowayME.f <- function(M, X, Z, level)
{
## A function to generate 2-way marginal effects plots in R.
## Written by Joshua Gubler ~ http://scholar.byu.edu/jgubler; originally
## based on Stata code from Joel Selway and Brambor, Clark, and Golder.
## Last modified: 12 October 2014 (Move to ggplot2 and reduce output to
## values rather than graph - David Romney)
## Variables must be in the following order: y = x z (control variables
## here) xz. The model can include as many control variables as you need.
## M = an object of type "lm," "glm," or other estimation -- i.e. the object
## that contains the regression estimation you seek to plot.
## X = the variable whose effect on Y you seek to plot
## Z = the moderating variable (will be positioned on the X-axis of the
## plot)
## xlab = label for x-axis (in quotes)
## ylab = label for y-axis (in quotes)
## level = to set the confidence level. Two options (don't put these in
## quotes): 95, 90. If you do not specify either option, the confidence
## intervals will not be correct.
## Example: TwowayME.f(estimation.lm, ses, edu, "Education levels",
## "Effect of SES on Civil War", 90)
S <- summary(M)
N <- c(1:20)
## 20 equally-spaced values for the moderating variable
zmin <- rep(min(Z, na.rm = TRUE), 20)
zmax <- rep(max(Z, na.rm = TRUE), 20)
Znew <- (((N - 1) / (20 - 1)) * (zmax - zmin)) + zmin
## Grab elements of coefficient and vcov matrix
H <- head(S$coefficients, 3)
T <- tail(S$coefficients, 1)
b <- rbind(H, T)
Vcov <- vcov(M)
Vcov <- as.data.frame(Vcov)
Vcov1 <- Vcov[, c(1:3)]
Vcov2 <- Vcov[, -c(0:0 - length(Vcov))]
Vcov <- cbind(Vcov1, Vcov2)
Vh <- head(Vcov, 3)
Vt <- tail(Vcov, 1)
V <- rbind(Vh, Vt)
b1 <- b[2, 1]
b2 <- b[3, 1]
b3 <- b[4, 1]
varb1 <- V[2, 2]
varb2 <- V[3, 3]
varb3 <- V[4, 4]
covb1b3 <- V[4, 2]
covb2b3 <- V[4, 3]
## Calculate ME values
conb <- b1 + b3 * Znew
## Calculate standard errors when W = 0, W = 1, W = 2, W = 3, and when W = 4
conse <- sqrt(varb1 + varb3 * (Znew^2) + 2 * covb1b3 * Znew)
## Upper and lower CIs
ci <- NA
ci[level == 95] <- qnorm(0.975)
ci[level == 90] <- qnorm(0.95)
a = ci * conse
upper = conb + a
