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.
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.
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.
outer.labels
for adding labels along outside edges of corrgram. (Request of Vanessa Bruat and others.)Function corrgram()
now returns the correlation matrix.
Fixed custom label ordering when order=TRUE
for M.Bruneaux.
Began using testthat
package.
New panel function panel.cor
for colored correlation values.
Fixed minor bugs with no complete cases.
Added more cases to tests directory.
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).
Updated references links. (Request of Michael Friendly).
Fixed small bug with test for correlation matrix. (Reported by F. Rosa)
New argument col.regions
to specify panel colors.
Re-worked examples section for more variety.
New panel function panel.bar
. (Request of dadrivr)
Added example for unclipped labels (in the test suite).
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.
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.
