ggerror 0.3.0

• ggerror now includes a complete aestetic support for one sided error bars.
• Added fixed per-side styling parameters for error bars: colour_neg / colour_pos, fill_neg / fill_pos, linewidth_neg / linewidth_pos, linetype_neg / linetype_pos, alpha_neg / alpha_pos, and width_neg / width_pos.
• Fixed bug from 0.2.0: When supplying one-sided error bars, the unused side’s width can be set to 0, default, for example geom_error(aes(error_neg = 0, error_pos = se), width_neg = 0).
• Added a vignette("ggerror") covering symmetric, asymmetric, one-sided, and per-side styling workflows.

ggerror 0.2.0

• New error_neg / error_pos aesthetics for asymmetric error bars. The bar extends error_neg in the negative direction and error_pos in the positive direction along the non-categorical axis.
• One-sided bars are supported by setting the unused side to 0 explicitly (e.g. aes(error_neg = 0, error_pos = se) for an upward-only bar).
• The existing symmetric error aesthetic is unchanged. Combining error with either error_neg / error_pos, or providing only one of the asymmetric pair, raises an error.

ggerror 0.1.0

• Initial release. Provides geom_error() (plus geom_error_linerange(), geom_error_crossbar(), geom_error_pointrange()) wrapping ggplot2’s error geoms behind a single error aesthetic with automatic orientation inference.
