I have managed to make a 2×2 plot using grid.arrange:

library(gridExtra)
grid.arrange(p1,p3,p2,p4, ncol=2, nrow=2, top = "Daily QC: Blue")

The main title of this multiplot is very small. Is there a way to change the title text size and font.

    main=textGrob("Daily QC: Blue",gp=gpar(fontsize=20,font=3))

    Edit with v>=2.0.0 of gridExtra, main has become top (for consistency with bottom, left and right).
