Connect observations by stairs.

Connect observations by stairs.

Usage
geom_step(mapping = NULL, data = NULL, stat = "identity",
    position = "identity", direction = "hv", ...)
Arguments
direction
direction of stairs: 'vh' for vertical then horizontal, or 'hv' for horizontal then vertical
mapping
The aesthetic mapping, usually constructed with aes or aes_string. Only needs to be set at the layer level if you are overriding the plot defaults.
data
A layer specific dataset - only needed if you want to override the plot defaults.
stat
The statistical transformation to use on the data for this layer.
position
The position adjustment to use for overlappling points on this layer
...
other arguments passed on to layer. This can include aesthetics whose values you want to set, not map. See layer for more details.
Aesthetics

[results=rd,stage=build]{ggplot2:::rd_aesthetics("geom", "step")} # Simple quantiles/ECDF from examples(plot) x <- sort(rnorm(47)) qplot(seq_along(x), x, geom="step")

# Steps go horizontally, then vertically (default) qplot(seq_along(x), x, geom="step", direction = "hv") plot(x, type = "s") # Steps go vertically, then horizontally qplot(seq_along(x), x, geom="step", direction = "vh") plot(x, type = "S")

# Also works with other aesthetics df <- data.frame( x = sort(rnorm(50)), trt = sample(c("a", "b"), 50, rep = TRUE) ) qplot(seq_along(x), x, data = df, geom="step", colour = trt)
