r plotting multiple series and custom x axis labels

I have data as below. I want to plot series y1 and y2 in different color lines and x axis labels should be values from variable x1. I am getting an error :(

x1=c("a","b","c")
y1=c(1,2,0)
y2=c(4,5,2)
plot(y1,xaxt='n',type="l")
axis(side = 1, at = x1,labels = T)

NAs introduced by coercionError in axis(side = 1, at = x1, labels = T) : no locations are finite

i would prefer if first 2 x axis labels come from x1 and third one is M. Something like c(x[1:2],"M")...how could I put custom labels?

eidt:

plot(1:3, y1, xaxt='n', type="l", ylim=range(c(y1, y2)))
points(1:3, y2, type = "l", col = "blue")
axis(side = 1, at = 1:3, labels = c(x1[1:2],"M"))
text(1:3, y1, y1)
text(1:3, y2, y2)
#

Is this what you are after? 

   plot(y1, xaxt='n', type="l")
   axis(side = 1, at = 1:3, labels = c(x1[1:2],"M"))

I think you have to specify values at where your labels should go. Above works.
