only when essential to the package. These packages have it in Depends/Imports but seem not to actually call it in their checks (established using a fake install). It is possible that the sole purpose of the package might be to do interactive visualizations which are not checked, but that seems not to be the case here. We noticed calls to rgl functions in \dontrun{}, but they would better be conditioned by if(interactive()) (see 'Writing R Extensions'). Please move rgl to Suggests and use conditionally (see ยง1.1.3.1 of 'Writing R Extensions') at the next package update.""
require(rgl)
because that crashes R for some users, so use if("rgl" %in% installed.packages() )
to check for installation and then call functions rgl::open3d()
Please use gge(data,formula)
instead of gge(formula,data)
.
New argument ggb=TRUE
to request construction of GGB biplot.
Use cex.gen=0
to omit genotype names.
On some Windows machines, library(rgl)
crashes R, perhaps because of a dll conflict with Windows. Removed @import rgl
so that rgl
is not loaded by default, and now biplot3d
uses calls like rgl::text3d
.
The nipals()
function using C++ code has been removed.
The rnipals()
function has been removed.
The gge
package now imports the nipals
package, which is new.
New function nipals()
for finding principal components using C++. Code from pcaMethods
package.
New function rnipals()
for finding principal components in R.
New function biplot3d()
to draw 3d biplots using rgl
package.
Modifed main
, subtitle
, xlab
, ylab
arguments to allow removal.
Changed title
argument to main
for consistency with other packages.
Now using testthat
and covr
packages.
Added package logo on GitHub.
Added zoom.gen
and zoom.env
arguments to biplot()
for M.Zoric.
Moved tests to tests/gge_tests.R
Package gge
is split off from agridat
package.
Added origin
, hull
arguments to biplot()
.
gge()
to agridat package.gge()
to fit and plot GGE biplots.(2007) Created nipals()
based on pcaMethods::nipalsPca()
. Modified the function for faster execution and submitted a patch back to pcaMethods
.
(2010) Henning Redestig created a C++ version of NIPALS for the pcaMethods
package.
(2017) The gge::nipals()
R function is re-named rnipals()
, and a new nipals()
function is created, based on the C++ code in pcaMethods
. Released gge version 1.2.
(2017) Discovered that mixOmics::nipals()
is a pure R function that is faster than the C++ version, so gge::nipals()
was re-written into a pure R function. The C++ version was removed from the gge
package.
(2017) The gge::nipals
function is moved to a new package, nipals::nipals
. The function is optimized for performance, improved to better handle missing values and to orthogonalize the principal components.
