[R] Help with the plot function

Hi

You are quite close. With slight modification of your code:

par(mfrow = c(2, 1))
par(cex = 0.6)
par(mar = c(0, 0, 0, 0), oma = c(4, 4, 0.5, 0.5))
par(tcl = -0.25)
par(mgp = c(2, 0.6, 0))

plot(BUD~YEAR, type="o", ann=F, axes=F, pch=19, ylim=c(60,100),data=g1)
axis(4, las=2)
mtext("Bud Break (Julian Day)", side=4, padj=4)
arrows(g1$YEAR,g1$BUD, g1$YEAR,g1$BUD + g1$BUD_SE, length=0.05, angle=90)
arrows(g1$YEAR,g1$BUD, g1$YEAR,g1$BUD-g1$BUD_SE, length=0.05, angle=90)

plot(T_MAR~YEAR, type="l", pch=19, ann=F, axes=F, xlim=c(1996,2004), ylim=c(0,12), data=g1)

title(ylab="Temperature (°C)",xlab="Year")
axis(1, at=seq(1996, 2004, 2))
axis(2, at=c(0,3,6,9,12), las=2)

I am quite close to what you probably expect. You need modify axes and their annotation, which is left for your training.

Cheers
Petr
