[R] Compact presentation of multiple figures

[Michael Kubovy]

Dear r-helpers,

I have six panels: op(par(mfrow = c(2, 3),  xaxt = 'n', yaxt = 'n',  
pty = 's').
Each of them has a variable main = 'i',  and xlab = '', ylab = ''

I would like to achieve two things:
(1) a common x-axis label under panel 5, and one label to the left of  
panels 1 and 4
(2) minimal space between the panels.

I have looked for examples, and even the thorough "Les paramètres  
graphiques" didn't help me: I haven't been able to reduce the space  
between the rows of panels nearly enough. My best attempt:
par(pty = 's', xaxt = 'n', yaxt = 'n', mfrow = c(2, 3), mgp = c(1, 0,  
0), mar = c(1.1, 2.1, 1.1, 0.1))
