Plot two graphs in same plot in R
...ider ggplot package. The idea is to create a graphical object with basic aesthetics and enhance it incrementally.
ggplot style requires data to be packed in data.frame.
# Data generation
x <- seq(-2, 2, 0.05)
y1 <- pnorm(x)
y2 <- pnorm(x,1,1)
df <- data.frame(x,y1,y2)

How to put labels over geom_bar for each bar in R with ggplot2
...
Try this:
ggplot(data=dat, aes(x=Types, y=Number, fill=sample)) +
geom_bar(position = 'dodge', stat='identity') +
geom_text(aes(label=Number), position=position_dodge(width=0.9), vjust=-0.25)

Increase number of axis ticks
...ggplot2)
dat <- data.frame(x = rnorm(100), y = rnorm(100))
ggplot(dat, aes(x,y)) +
geom_point()
Gives you this:
And overriding the scales can give you something like this:
ggplot(dat, aes(x,y)) +
geom_point() +
scale_x_continuous(breaks = round(seq(min(dat$x), max(dat$x), by = 0.5),1...
How to deal with “data of class uneval” error from ggplot2?
... look at the arguments for ?geom_line.
Thus:
p + geom_line(data=df.last, aes(HrEnd, MWh, group=factor(Date)), color="red")
Or:
p + geom_line(aes(HrEnd, MWh, group=factor(Date)), df.last, color="red")
