pointswithslantederror: pointswithslantederror

Description

This function plots points with x- and y-errors visualised as a slanted errorbar. The length of the error bar represents x- and y-errors added in quadrature. The slope of the error bar is positive of negative depending on whether the correlation betwenn x and y is positive or negative, respectively.

Usage

pointswithslantederror(x, y, dx, dy, cor, col = "black", bcol = "black", ...)

Arguments

x

numeric vector. x-values

y

numeric vector. y-values

dx

numeric vector. x-standard errors

dy

numeric vector. y-standard errors

cor

numeric vector. Correlation coefficients between x- and y- errors.

col

the color of the points

bcol

the color of the slanted error bars

...

further graphical parameters to be passed on to points
