You can add following line to get a map without frame.
par.settings=list(axis.line=list(col=NA))
For tittle,
main=list("(a) tittle",cex=.6)
For size and space between frames (for nine frames):
windows(width=5.5, height=8)
tiff( file="Fig.tif",width=5.5, height=8,units = "in", pointsize = 12, 
res=1600,
restoreConsole = T,compression =  "lzw",bg="transparent")

print(a,position = c(0.05,0.5,1,1),split=c(1,1,4,2), 
more=TRUE,panel.width=list(1.5, "inches"),panel.height=list(1.5, "inches"))
print(b,position = 
c(0.15,0.5,1,1),split=c(2,1,4,2),more=TRUE,panel.width=list(1.5, 
"inches"),panel.height=list(1.5, "inches"))
print(c,position = c(0.45,0.5,1,1), split=c(3,1,4,2), 
more=TRUE,panel.width=list(1.5, "inches"),panel.height=list(1.5, "inches"))
print(d,position = c(0.05,0.5,1,0.65),split=c(1,1,4,2),
