Hello everyone
I have problem with axis labels on graphs, I have my code as below:
plot(0,0,xlim=c(1,ncol(PA)),ylim=c(1,nrow(PA)),main="Stratigraphic
Range",xlab="Time
Bins",ylab="Taxa",cex.axis=1.5,cex.lab=2,cex.main=2.5,mgp=c(5,1.5,0),xaxt="n")
text(1:(length(strat_name)), y= 0, adj=1,
srt=45,labels=strat_name,xpd=TRUE, cex=1) #adds text to x axis giving
the strat names
abline(v=(1:ncol(PA))+.5,col="grey",lty=3)
cl <- rep(1,nrow(PA))
cl[DistM$kill] <- 2
for (i in 1:nrow(PA)) segments(min(which(PA[i,]==1))-.5,i,
max(which(PA[i,]==1))+.5,i,lwd=3,col=cl[i])
My problem lies with the x axis tick labels, I want my own labels
added in so removed the one the plot function adds in normally.
I use the text function as it allows me to fit my own text tick labels
at an angle, HOWEVER the text function is VERY sensitive to the Y
axis, I have multiple graphs on a page, each with a different y axis,
so the labels move up and down depending on the scale of the Y.
I tried using mtext which lets you put the text a certain distance
from the x margin line, HOWEVER this function does not let you tilt
the text to be an an angle
Can anyone tell me of a way I can have both - ie text that is a
specified distance from the margin AND tilted at and angle
Thanks
Martin
