try text(c("1970", "1978", "1990"), x=1:3, y=1:3) after you first
call plot(c(1, 3), c(1, 3), axes=F, type="n", xlab="", ylab="")
to set the plotting area.

I am an R novice trying to figure out plot().
Specifically, I am trying to plot the values of a
numeric variable V for a set of years (1970, 1974,
1976, 1978, 1980). How do I get R to label the years
I am plotting on the x-axis rather then some general
levels (1970, 1975, 1980.) Using as.character(year)
doesn't seem to help, and using as.factor(year)
generates steps insteads of dots.
Help will be most appreciated. I have listed the code
I have been using below:
> plot(y$year, y$V, type = "b")
> plot(as.character(y$year), y$V, type = "b")
> plot(as.character(y$year), y$V, type = "b")
Thanks,
NR
