corrgram 1.15 ()

• Happy 20th anniversary for this package in 2026.

• Add lattice panel functions to make lattice corrgrams.

• Add corrgram2() to make grid-based corrgrams.

• Documentation pages now created via Github Actions.

• Remove corrgram(..., font.labels) argument.

• Switch to MIT license

corrgram 1.14 (2021-04-01)

• The seriation package is moved from Imports to Suggests. This makes corrgram lighter loading for most people. (Requested by P.Kiener and others)

• The outer.labels argument has improved default values.

corrgram 1.13 (2018-07-09)

• Test coverage at 95% using covr package.

• New panel.fill() function, omits diagonal lines.

• panel.conf and panel.cor now auto-scale based on absolute value of correlations.

• panel.conf now only allows cor.method="pearson" (which is the default.) Fix issue #13.

corrgram 1.12 (2017-05-07)

• New vignette about an invalid correlation matrix.

• corrgram() gives a better warning if a symmetric matrix has values outside [-1,1].

• Added package logo on github.

corrgram 1.11 (2017-04-03)

• New argument outer.labels for adding labels along outside edges of corrgram. (Request of Vanessa Bruat and others.)

corrgram 1.10 (2016-11-09)

• Function corrgram() now returns the correlation matrix.

• Fixed custom label ordering when order=TRUE for M.Bruneaux.

• Began using testthat package.

corrgram 1.9 (2016-07-16)

• New panel function panel.cor for colored correlation values.

• Fixed minor bugs with no complete cases.

• Added more cases to tests directory.

corrgram 1.8 (2015-07-03)

• Namespace changes due to R devel changes.

corrgram 1.7 (2015-02-13)

• Added more seriate options.

corrgram 1.6 (2014-08-29)

• Moved packages from Depends to Imports.

• Argument label.pos now defaults to c(.5, .5) for x,y positioning. (Request of Evan Williams).

• New argument cor.method. (Request of Evan Williams).

corrgram 1.5 (2013-08-29)

• Updated references links. (Request of Michael Friendly).

• Fixed small bug with test for correlation matrix. (Reported by F. Rosa)

corrgram 1.4 (2012-11-07)

• New argument col.regions to specify panel colors.

• Re-worked examples section for more variety.

corrgram 1.3 (2012-08-15)

• New panel function panel.bar. (Request of dadrivr)

• Added example for unclipped labels (in the test suite).

corrgram 1.2 (2012-03-28)

• Small bug. Now accepts NA values in correlation matrices, and NAs caused by missing combinations of data and cor(use=“pair”).

• Non-numeric columns in the data will be ignored. (Request of JZ)

• New panel function panel.density.

• Test suite now includes corrgram of inverse correlation, partial correlation matrices.

corrgram 1.1 (2011-10-20)

• Added namespace.

corrgram 1.0 (2011-07-02)

• New panel function panel.conf.

• New data set vote.

• New arguments dir, type, label.srt, title, abs.

• Now works for either a data.frame or a correlation matrix using the type argument.

• New ordering method OLO using seriation package.

• Ordering can now be done on absolute value of correlations.

corrgram 0.1 (2006-12-01)

• First release to CRAN.
