Apologies! I though that the Orange dataset comes with R, but it is in
fact in the package "datasets".
So here's another "Orange2" dataset for the example:
Tree_v = rep(c(1:5),each = 5)
age_v = rep(seq(1,25, by = 5),5) + 10*runif(25)
circumference_v <- rep(seq(21,45, by = 5), 5)*Tree_v + 25*runif(25)
Orange2 <- data.frame(Tree = as.factor(Tree_v), age = age_v,
circumference = circumference_v)
This works fine:
ggplot(data = Orange2, aes(x = age, y = circumference, color = Tree))
+ geom_line()
These generate errors (included):
> ggplot(data = Orange2, aes(x = age, y = circumference, color = Tree, linetype
> = Tree)) + geom_line()
Error in get("check_domain", env = ., inherits = TRUE)(., ...) :
Too many values in domain (5 > 4)
> ggplot(data = Orange2, aes(x = age, y = circumference, color = Tree)) +
> geom_line() + scale_linetype_manual(value = c(1:5))
Error in unit(values, units, data = data) :
'x' and 'units' must have length > 0
What am I doing wrong?
Regards,
TL
