changing title in multiplot ggplot2 using grid.arrange

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).

Due to changes in both packages grid and gridExtra, the current answer is outdated. Library package grid is also required to use textGrob and gpar.

The new code should include both packages:

library(grid)
library(gridExtra)
grid.arrange(p1,p3,p2,p4, ncol=2, nrow=2,
     top = textGrob("Daily QC: Blue",gp=gpar(fontsize=20,font=3)))
