In TobieSurette/gulf.graphics: Southern Gulf Graphics Functions

Draw Error Bars

Description

Draw error bars with specified error levels at the specified coordinates.

Usage

error.bar(
  x,
  y,
  sigma,
  lower,
  upper,
  polygon = FALSE,
  col = "grey30",
  border,
  add = TRUE,
  ...
)

Arguments

x	Horizontal coordinates.
y	Central value(s) or lower and upper bound(s).
sigma	Error deviation from y to be used to define the lower and upper error bounds.
lower	Lower error bound or deviation (if sigma is specified).
upper	Upper error bound or deviation (if sigma is specified).
add	Logical value specifying whether the error bars are to be added to the current plot (Default is TRUE).

Examples

# Constant error:
error.bar(1:10, y = rnorm(10), sigma = 2, add = FALSE)
 
# Variable error:
error.bar(1:10, y = rnorm(10), sigma = 0.5 + runif(10), add = FALSE)

# Explicit bounds:
error.bar(1:10, lower = 2, upper = 2 + runif(10), add = FALSE)
