inter tick distance

R colleagues, I am stumped. I would like the inter-tick distances to be the same on the x and y axes but cannot determine how to do so when the lower half of the y axis is not printed. Thanks for any and all suggestions. (btw, setting par(pty="s") does not solve my problem) Niels Waller
This is a tough one. I think I would a) set xaxs and yaxs to "i" b) set xlim and ylim c) set pin to be proportional to the chosen limits. Try replacing the last bit of your example with par(pin=c(6,6)) plot(c(-4,4),c(0,4),type="n",xaxs="i",yaxs="i", xlim=c(-3,3),ylim=c(-1,5),axes=FALSE,xlab="",ylab="") axis(side=1,pos=0,labels=FALSE) axis(side=2,pos=0,labels=FALSE,at=c(0,1,2,3,4)) arrows(0,0,M[1,1],M[1,2],angle=20,length=.15,lwd=2) arrows(0,0,M[2,1],M[2,2],angle=20,length=.15,lwd=2)
M<-matrix(c(2,1,
-1,3),2,2,byrow=TRUE)
dimnames(M)<-list(c("P1","P2"),c("V1","V2"))
writeLines(text=c("\n","Matrix M"))
print(M)
plot(c(-4,4),c(0,4),type="n",xlim=c(-3,3),axes=FALSE,xlab="",ylab="")
axis(side=1,pos=0,labels=FALSE)
axis(side=2,pos=0,labels=FALSE,at=c(0,1,2,3,4))
arrows(0,0,M[1,1],M[1,2],angle=20,length=.15,lwd=2)
arrows(0,0,M[2,1],M[2,2],angle=20,length=.15,lwd=2)
