R help - Jun 2013 - lineplot.ci{sciplot}: Split x.factor label in two lines

Some of the levels in my X factor has more than one word (e.g., North
America) which I would like to split into two lines so that my plot does
not get too wide. Any help is appreciated.

lineplot.CI(x.factor = Continent, response = PCC.PrsPts, group PointSource, data
= master2, cex = 1.2,
 xlab = "", ylab = "Sensitivity", ylim = c(0.37,1.01),
cex.lab = 0.9, x.leg
= 0.9, y.leg = 0.6, cex.leg=0.75, ncol=1, cex.axis=0.85,
 main = "",
col =  c (colorRampPalette(c("red", "orange"))  (2),
 colorRampPalette(c("blue", "green"))  (2),
colorRampPalette(c("purple", "black")) (2)),
 pch = c(19,19,18,1817,17))
