geom_bar | R Documentation |
Show interval data as vertical bar, width equals to interval width and use 'score' or specified 'y' as y scale.
## S4 method for signature 'ANY'

Title for plot. |
Useful for showing bed like files, when imported as GRanges, have a extra 'score' column, use it as default y, you could also specify y by using aes(y = ).
A 'Layer'.

score = rnorm(10, 10, 3), value = runif(10, 1, 100))
gr.b <- c(gr.b, gr.b2)
## default use score as y
## bar
ggplot(gr.b) + geom_bar(aes(fill = value))
## or
ggplot() + geom_bar(gr.b, aes(fill = value))
ggplot(gr.b) + geom_bar(aes(y = value))
## equal to
autoplot(gr.b, geom = "bar")
