News for Package proxy

Changes in version 0.4-27

• cosmetic changes in help pages

• add angular distance/similarity; keep old behavior as cosine

Changes in version 0.4-26

• Change coercion function for cosine similarity to distance to 1-x instead of 1-abs(x)

Changes in version 0.4-25

• fix scaling for gower metric in case of cross-proximities to scale x and y together.y

Changes in version 0.4-24

• fix tests in apply.R to comply to new default behavior of encoding character strings in data frames

Changes in version 0.4-23

• smaller changes in C code to prevent false positives from automated CRAN code checking

Changes in version 0.4-21.1

• Change registry class name to proxy_registry to prevent name clashes with registry package.

Changes in version 0.4-21

• some more C-code PROTECTing.

Changes in version 0.4-20

• print method for simil objects added that prints NA instead of 0 for diagonal elements, if requested.

Changes in version 0.4-19

• fix for binary distance (C-code): now has same behavior as the corresponding distance method in the stats package in case of missing values.

Changes in version 0.4-17

• pr_simil2dist now computes 1 - abs(x) instead of 1 - x.

Changes in version 0.4-15

• add imports from recommended packages.

Changes in version 0.4-14

• export as.matrix() generic.

Changes in version 0.4-11

• Make binary similarities work with binary data in case of list data (by coercing list to a matrix).

Changes in version 0.4-10

• Bug in Fager/McGown measure fixed.

Changes in version 0.4-9

• Author/Maintainer removed.

Changes in version 0.4-8

• PACKAGE="proxy" argument added to all .External-calls. "PACKAGE" field added to the registry, defaulting to "proxy", and used by .Call().

Changes in version 0.4-7

• the method argument of dist() now also accepts a registry entry to avoid unnecessary lookups in repeated calls to dist().

Changes in version 0.4-6

• bugfix: names<-.dist did not accept NULL as assignment.

Changes in version 0.4-5

• small vignette with an overview of existing methods added.

Changes in version 0.4-4

• Podani, Chord, geodesic, Hellinger and Whittaker dissimilarities added.

• Fager/McGown anf Faith similarities added.

Changes in version 0.4-3

• pr_dist2simil now computes 1 / (1 + x) instead of 1 / (1 - x)

• fix labeling bug for list data with named components

• the C-level dist functions now conform with those in package stats with respect to NA handling (pairwise-complete observations).

Changes in version 0.4-2

• as.matrix.dist by default now uses 0 for diagonal elements

Changes in version 0.4

• fix a bug in Kullback-Leibler-distance

Changes in version 0.3

• fixed Gower-dissimilarity

• fixed dist/simil subsetting

• self-proximities now default to NA

Changes in version 0.2

• data frames are auto-converted to matrices if all variables are either numeric, logical, or complex (to be compatible to stats::dist)

• pairwise distances can now be computed

• Registry is now case-insensitive

Changes in version 0.1

• Initial release
