geom_stepribbon {RcmdrPlugin.KMggplot2} | R Documentation |
Step ribbon plots.
Description
geom_stepribbon
is an extension of the geom_ribbon
, and
is optimized for Kaplan-Meier plots with pointwise confidence intervals
or a confidence band.
Usage
geom_stepribbon(
mapping = NULL,
data = NULL,
stat = "identity",
position = "identity",
na.rm = FALSE,
orientation = NA,
show.legend = NA,
inherit.aes = TRUE,
outline.type = "both",
kmplot = FALSE,
...
)
Arguments
mapping |
Set of aesthetic mappings created by |
data |
The data to be displayed in this layer. |
stat |
The statistical transformation to use on the data for this layer. |
position |
A position adjustment to use on the data for this layer. |
na.rm |
If FALSE, the default, missing values are removed with a warning. If TRUE, missing values are silently removed. |
orientation |
The orientation of the layer. |
show.legend |
logical. Should this layer be included in the legends? NA, the default, includes if any aesthetics are mapped. FALSE never includes, and TRUE always includes. It can also be a named logical vector to finely select the aesthetics to display. |
inherit.aes |
If FALSE, overrides the default aesthetics, rather than
combining with them. This is most useful for helper functions that define
both data and aesthetics and shouldn't inherit behaviour from the default
plot specification, e.g. |
outline.type |
Type of the outline of the area; "both" draws both the upper and lower lines, "upper"/"lower" draws the respective lines only. "full" draws a closed polygon around the area. |
kmplot |
If |
... |
Other arguments passed on to layer()'s params argument. |
Aesthetics
geom_stepribbon()
understands the following aesthetics. Required
aesthetics are displayed in bold and defaults are displayed for optional
aesthetics:
• | x or y |
• | ymin or xmin |
• | ymax or xmax |
• | alpha |
• | colour |
• | fill |
• | group |
• | linetype |
• | linewidth |

Examples
huron <- data.frame(year = 1875:1972, level = as.vector(LakeHuron))
h <- ggplot(huron, aes(year))
h + geom_stepribbon(aes(ymin = level - 1, ymax = level + 1), fill = "grey70") +
geom_step(aes(y = level))
h + geom_ribbon(aes(ymin = level - 1, ymax = level + 1), fill = "grey70") +
geom_line(aes(y = level))
