Hi R-users
I'm a relative newbie and uses R mostly for graphical purpose. I have a
layout problem when plotting a scatterplot and a barplot using
par(new=TRUE). The baseline of the x-axis is not positioned equal for the
two plotting functions (see picture) and I have been unable to find out how
this is changed.

I have added the script if this is of interrest:
par(mar = c(7, 4, 4, 2) + 0.1)
barplot(rbind(data$Asn,data$Glu,data$NH3),
beside=T,
axes=TRUE,
xlim=c(0,57),
ylim=c(0,10))
par(new=TRUE)
plot(1:14,data$Acidification.time,
axes=FALSE,
type="b",
xlab="",
ylab="",
xlim=c(0.3,14.7),
ylim=c(6,8))
axis(1,pos=6,
labels=FALSE,
at=c(0.3,1:14,14.7))
text(1:14, par("usr")[3], srt = 90, adj = 1,
labels = data$Month, xpd = TRUE)
axis(4,pos=14.7)
All help will be greatly appreciated
