R help - Feb 2013 - Why no line? (ex. from Andy Filed book)

The following script is written by the author of a book on R--Andy Field:
You can also download the small datafile, hiccups.dat, from this address:

http://www.sagepub.com/dsur/study/articles.htm

The script:

hiccupsData <- read.delim("Hiccups.dat",  header = TRUE)
hiccups<-stack(hiccupsData)
names(hiccups)<-c("Hiccups","Intervention")
hiccups$Intervention_Factor<-factor(hiccups$Intervention, levels
hiccups$Intervention)

line <- ggplot(hiccups, aes(Intervention_Factor, Hiccups))
line + stat_summary(fun.y = mean, geom = "point") + stat_summary(fun.y
mean, geom = "line", aes(group=1),colour = "Red", linetype =
"dashed")+
stat_summary(fun.data = mean_cl_boot, geom = "errorbar", width = 0.2)
+
labs(x = "Intervention", y = "Mean Number of Hiccups")
saveInImageDirectory("04 Hiccups Line.png")

Why does this script not give me a line?

It's driving e crazy :-|

Hi

The code gives me some warnings but all seems to be OK. 4 points, dashed red
line and error bars. Did you expect some other line?

maybe issue of version/OS? (unstated)
