Those are still expressions, not v...

Graphics question
Hi
I am trying to plot two points (with confidence intervals) on a graph to
illustrate the value of a particular quantity after 1 and 2 iterations
respectively.
I'm doing this by
plot(cycle,alpha[2,],main="",ylim=c(-8,-3),cex=2,col="red",pch=19,ylab=e
xpression(alpha),xlab="cycle")
Etc..
Where
> cycle
[1] 1 2
> alpha
[,1] [,2]
[1,] -6.227266 -5.762146
[2,] -5.200972 -5.010401
[3,] -4.174677 -4.258655
When I plot this I get the x-axis scale reading 1.0,1.1,1.2,...,2.0
I want to get it to read simply 1...

Anyone who knows C and samba better than I do have any ideas?
