Dear R-help,
I am trying to plot some data in a plot where I leave a big margin free to add
other information, namely text and points.
I am now struggling with keeping the size of the margin, text and points in a
fixed ratio. I want this so that the layout of the figure does not change every
time I plot new data.
I have:
a<-8
counter<-1
spacing<-a/(3*a)
adding<-a/(3*a)
start<-a*(a/3)
alphabet<-c("A","A","A","A","A","A","A","A")
x<-c(1,2,3,4,5,6,7,8)
y<-c(10,20,30,40,50,60,70,80)
png(file="TESTING.png", units="in", width=a, height=a, res=a*100)
par(xpd=NA,mar=c(0,0,0,0),oma=c(0,0,0,(3*a))) #bottom, left,top, right
plot.new()
plot(x,y)
points(pch=20,10, 10, cex=5)
text(10,10, alphabet, cex=5, col="blue")
What I do not understand is why the size of the point and the text is not the
same and why the margin can be "bigger" than the width of the figure.
BASICALLY, the units of the margins, the points and the text are not the same...
What I need is a way to make the size of the point and text AND the margin
independent of the data I plot so that the figure always looks the same
although there is more data in it in some cases (for example 10 or 20 points
with text in the margin).
This could be done by setting the units of points, text and margin to inches so
that a is the same for all of them... Or to know the ratio between the
different units used by R for margin, points and text...
Any ideas on how to solve that?
Please let me know if clarifications are needed!
