geom_crossbar {animint2} | R Documentation |
Vertical intervals: lines, crossbars & errorbars.
Description
Various ways of representing a vertical interval defined by x
,
ymin
and ymax
.
Usage
geom_crossbar(
mapping = NULL,
data = NULL,
stat = "identity",
position = "identity",
...,
fatten = 2.5,
na.rm = FALSE,
show.legend = NA,
inherit.aes = TRUE
)
geom_errorbar(
mapping = NULL,
data = NULL,
stat = "identity",
position = "identity",
...,
na.rm = FALSE,
show.legend = NA,
inherit.aes = TRUE
)
geom_linerange(
mapping = NULL,
data = NULL,
stat = "identity",
position = "identity",
...,
na.rm = FALSE,
show.legend = NA,
inherit.aes = TRUE
)
geom_pointrange(
mapping = NULL,
data = NULL,
stat = "identity",
position = "identity",
...,
fatten = 4,
na.rm = FALSE,
show.legend = NA,
inherit.aes = TRUE
)
Arguments
mapping |
Set of aesthetic mappings created by |
data |
The data to be displayed in this layer. There are three options: If A A |
stat |
The statistical transformation to use on the data for this layer, as a string. |
position |
Position adjustment, either as a string, or the result of a call to a position adjustment function. |
... |
other arguments passed on to |
fatten |
A multiplicative factor used to increase the size of the
middle bar in |
na.rm |
If |
show.legend |
logical. Should this layer be included in the legends?
|
inherit.aes |
If |
Aesthetics
geom_linerange
understands the following aesthetics (required aesthetics are in bold):
x
ymax
ymin
alpha
colour
linetype
size

Examples
#' # Create a simple example dataset
df <- data.frame(
trt = factor(c(1, 1, 2, 2)),
resp = c(1, 5, 3, 4),
group = factor(c(1, 2, 1, 2)),
upper = c(1.1, 5.3, 3.3, 4.2),
lower = c(0.8, 4.6, 2.4, 3.6)
)
p <- ggplot(df, aes(trt, resp, colour = group))
p + geom_linerange(aes(ymin = lower, ymax = upper))
p + geom_pointrange(aes(ymin = lower, ymax = upper))
p + geom_crossbar(aes(ymin = lower, ymax = upper), width = 0.2)
p + geom_errorbar(aes(ymin = lower, ymax = upper), width = 0.2)
# Draw lines connecting group means
p +
geom_line(aes(group = group)) +
geom_errorbar(aes(ymin = lower, ymax = upper), width = 0.2)
# If you want to dodge bars and errorbars, you need to manually
# specify the dodge width
p <- ggplot(df, aes(trt, resp, fill = group))
p +
geom_bar(position = "dodge", stat = "identity") +
geom_errorbar(aes(ymin = lower, ymax = upper), position = "dodge", width = 0.25)
# Because the bars and errorbars have different widths
# we need to specify how wide the objects we are dodging are
dodge <- position_dodge(width=0.9)
p +
geom_bar(position = dodge, stat = "identity") +
geom_errorbar(aes(ymin = lower, ymax = upper), position = dodge, width = 0.25)
