Hi Hadley, recently I run this code however got following error (this error
seems not be there at 1st time) :
> dat <- data.frame(x = rnorm(100))
> dat1 <- data.frame(
+ x = c(0,0),
+ y = c(1,0),
+ Label = c("Point1", "Point2")
+ )
>
>
> ggplot(dat, aes(x)) +
+ geom_histogra
You mean:
dat <- data.frame(x = rnorm(100))
dat1 <- data.frame(
x = c(0,0),
y = c(1,0),
Label = c("Point1", "Point2")
)
ggplot(dat, aes(x)) +
geom_histogram(aes(fill = ..count..)) +
geom_point(aes(x, y, colour = Label), data = dat1, size = 4) +
scale_fill_gradient("Count", low = "gre
Here I have following code :
dat = rnorm(100)
ggplot() + geom_histogram(aes(dat, fill=..count..)) +
scale_fill_gradient("Count", low="green", high="red") +
opts(legend.position="none")
# Above is without any legend
## Now I want to place two points with legends
dat1 <- data.frame(c(0,0), c(1,0))
