[R] How to make two figures in one plot - package vcd

[Muhammad Subianto]

Dear all,
I have a problem to make figures with two columns in package vcd.
Here an example code I take from "\library\vcd\html\plot.loglm.html"
What I need, I want to make two figures in one plot.
How could I do that.
I have tried with
layout(rbind(c(1, 1, 2, 2)))
but the same result, two plot.

Best wishes, Muhammad Subianto

library(vcd)
oldpar <- par(mfrow=c(1, 2))
## mosaic display for PreSex model
data(PreSex)
fm <- loglm(~ PremaritalSex * ExtramaritalSex * (Gender + MaritalStatus),
             data = aperm(PreSex, c(3, 2, 4, 1)))
## visualize Pearson statistic
plot(fm, split_vertical = TRUE)
## visualize LR statistic
plot(fm, split_vertical = TRUE, residuals_type = "deviance")
par(oldpar)
