So, I am trying to label the points in a graph, but cannot quite figure
out how to use ltext. I get an error about the lengths of x and y not
being the same, when I have defined them as the same.
> a <- data.frame(num = 1:4)
> a$country <- c("A", "B", "C", "D")
> a$p <- c(0.34, .54, .41, .33)
> a$q <- c(.07, .03, .05, .10)
> a
num country p q
1 1 A 0.34 0.07
2 2 B 0.54 0.03
3 3 C 0.41 0.05
4 4 D 0.33 0.10
> xyplot(p ~ q, data = a, ltext(x=x, y=y, label = a$country))
Error in xy.coords(x, y) : x and y lengths differ
> xyplot(p ~ q, data = a, groups = as.character(a$country), ltext(x=x,
y=y, label = groups[subscripts]))
Error in xy.coords(x, y) : x and y lengths differ
