par(mfrow=c(3,1)) not working?

[Guido]

Hello,

I have itemplots of a few items that I want to print in 1 figure.

However something like par(mfrow=c(3,1)) does not work. The plot keep printing separately.

Patchwork only works voor ggplot

plot(c(traceplot1,traceplot2,traceplot3)) does work in a way but the main title cannot be changed and I can't seem to put a unique title on top of the individual plots.

Any other solutions?

The patchwork package should work for lattice objects as well (ggplot2 and lattice are both grid-based graphics). Failing that you could use the gridExtra::grid.arrange() function to organize the plots yourself.
