Dear all,
I am fairly new to package Plotrix and I would like to ask you, if any of
you could help me with following.
a) I don't know how to set up border line width in the Stackpoly function
(seems that lwd from par doesn't work, or at least not in the way I have
written)
b) I don't know, how to rotate the x axis labels (I used srt=45, but same
problem as before).
c) Could anyone clarify to me, what does e.g. col= par("col") stand
for in
the usage explanation? Does it somehow change the way I should call such
parameter?
d) the three dots in stackpoly usage are calling other parameters from plot,
however if in plot there are the three dots calling parameters from par, am
I able to call parameters from par directly in stackpoly?
Could anyone please help me?
Thank you, best regards, Vaclav

library(plotrix)
xpopis<-c(0.9,0.99,0.999)
paste("1 in",round(1/(1-xpopis),1),sep=" ")
#n as number of subjects is 4
result<-c(0.3,0.15,0.4,0.15,0.5,0.1,0.12,0.28,0.45,0.25,0.2,0.1)
stackpoly(x=matrix(nrow=3,ncol=4,xpopis),y=matrix(nrow=3,ncol=4,result,byrow=T),
xlim=c(0.85,1),ylim=c(0,1),
xaxlab=paste("1 in",round(1/(1-xpopis),1),sep="
"),xat=xpopis,
col=c("blue","red","green","cyan"),
border=gray(0.4),lty="dotted",lwd=0.1,stack=T,srt=45)
#lwd not working, how to make the border lines smaller?
#how to add srt of the x axis labels to be = 45? i.e. to rotate x axis
labels by 45 degrees?
Thank you, best regards, Vaclav

Let's take them one by one. a) There is no way to specify border width at the moment. stackpoly is a fairly new function, and I usually program these with minimal options and let the users tell me what is missing. In the modified function below, there is a "lwd" argument that allows the user to specify this. b) If you want to have angled tick labels, you will have to roll your own with text(). First set par(xpd=TRUE), then display the labels, then set par(xpd=FALSE). Unfortunately axis() doesn't obey the srt argument. c) I can't find the reference to col=par("col") in the help page (stackpoly uses col=NA). par("col") returns the current drawing color (default is black) and would be unlikely to be useful as you would get one big black polygon. The default is to use rainbow() to specify the colors, or the user can pass one or more colors that will define the fill colors for the polygons. d) I think so. If the ... arguments are after any arguments that plot() recognizes, I think they will be passed to par(), but I can't say for sure. The modified stackpoly function will appear in plotrix 2.7-1.

If you make your third line in the call: xaxlab=c("","",""),xat=xpopis, and then: par(xpd=TRUE) text(c(0.9,0.99,1),c(-0.06,-0.06,0.06), c("1 in 10","1 in 100","1 in 1000"),srt=45) I think you will get what you want.
