Hi
I'd appreciate some help with plotting odds ratios. I want to rotate the
labels on the x-axis by 45 degrees.
The usual way of doing this, using text - e.g. text(1,
par('usr')[3]-2.25..)
- gives no result when the y-axis is a log scale.
I guess this is because, as the par help says, for a logarithmic y-axis:
y-limits will be 10 ^ par("usr")[3:4]
Does anyone know a solution for this?
The example below works well if log='y' is omitted.
Thanks very much for your help
Tim
#Create plot with log-scale on the y-axis
par(mar = c(7, 4, 4, 2) + 0.1)
plot(1, type='n', bty='n',
xlab="",
ylab='Odds Ratio',
xlim= c(0.5,4.5),
ylim= c(0.75, 2),
cex=2, xaxt='n', yaxt='n', cex.lab=1.3,
log='y')
# Line of unity
segments(0,1,10,1, lwd=2, lty=2)
#Estimates and confidence intervals
points(c(1:4),c(1.1,1.32,1.14,1.36), pch=17, cex=1.5, col='blue')
segments (c(1:4),c(0.93,1.11,0.94,1.15),c(1:4),c(1.3,1.58,1.37,1.61),
col='blue', lwd=2)
axis(1,c(1:4), labels= F)
axis(2, at=seq(0.75,2, by=0.25), labels=seq(0.75,2, by=0.25), las=1)
labels <- paste("Label", 1:4, sep = " ")
text(1:4-0.25, par('usr')[3]-0.15, xpd=TRUE, labels=labels, adj=0.1,
srt=45)
mtext("Exposure", side=1, line=4.5, cex=1.5)

Hi ALL I want to run a program on my office computer, but for some reason I have to run it later when I am not in the office anymore. Is there a way to do it? Can I run a program now but in the beginning I say that the rest should be run 3 hours later for example? Thanks a lot Leila
have a look at Sys.sleep(), i.e., you probably need Sys.sleep(3*3600) I hope it helps.
