direct.label error : Even directlabels manual example is not working

I have encountered a problem with an old script using direct.label but it seems more than just an out-of-date script.

I tried to run the gqplot example from the directlabels manual and it did not work. The lattice example did and I have no idea what the error message is trying to tell me.

Error in switch(geom, density = "top.bumptwice", line = { :
EXPR must be a length 1 vector

If I try using geom_dl example from the manual I get a different error message but I am still clueless.

Error in eval(expr, envir, enclos) : could not find function "eval"

I updated all packages last week IIRC so I was wondering if I have an incompatibility?

Toy example:

mdat1 <- structure(list(tmonth = c(4L, 5L, 6L, 7L, 8L, 9L, 10L, 4L, 5L,
6L, 7L, 8L, 9L, 10L, 4L, 5L, 6L, 7L, 8L, 9L, 10L), variable = structure(c(1L,
1L, 1L, 1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 3L, 3L, 3L,
3L, 3L, 3L, 3L), .Label = c("nsw", "qld", "vic"), class = "factor"),
    value = c(2L, 6L, 5L, 2L, 1L, 5L, 6L, 6L, 5L, 8L, 4L, 6L,
    5L, 4L, 9L, 2L, 4L, 6L, 8L, 7L, 5L)), row.names = c(NA, -21L
), .Names = c("tmonth", "variable", "value"), class = "data.frame")

library(ggplot2)
library(reshape2)
library(directlabels)

p <- ggplot(mdat1, aes(tmonth, value, colour = variable)) + geom_line()
print(direct.label(p))

Hi John,

Your sessionInfo() says you have directlabels version 2013.6.15.
Updating to the most recent release should work (it does for me).

Best,
Ista

Ista and John,

I was less lucky. I unloaded everything extra and tried again with same results.

p <- ggplot(mdat1, aes(tmonth, value, colour = variable)) + geom_line()

print(direct.label(p))

Error in switch(geom, density = "top.bumptwice", line = { :

EXPR must be a length 1 vector

You might try using geom_dl() instead.

Thanks Hadley,

I had neglected to say that I had tried geom_dl as well.

BTW, I have changed my code to use geom_dl anyway. Much cleaner way to go.
