ErrorPoints(x = NULL, x.unc.lo = NA, y = NULL, y.unc.lo = NA,
  x.unc.hi = NULL, y.unc.hi = NULL, xlog = FALSE, xlog.value = 0.01,
  na.rm = TRUE, ...)

Arguments

x

a vector of x coordinates used as a centroid from which to draw segments.

x.unc.lo

a vector of uncertainites added and subracted from x to create segments.

y

a vector of y coordinatesused as a centroid from which to draw segments.

y.unc.lo

a vector of uncertainites added and subracted from y to create segments.

x.unc.hi

a vector of uncertainites added and subracted from x to create segments.

y.unc.hi

a vector of uncertainites added and subracted from y to create segments.

xlog

logical; if TRUE changes nonpositive values to xlog.value

xlog.value

default 0.01

na.rm

logical; if TRUE, NA values in x and x.unc (y and y.unc) values result in no vertical (horizontal) line being drawn.
