htmlwidgets News This Week
A gallery is up thanks to Ryan Hafen, but not “official”. As always, for all the newest and updated
htmlwidgets, just do this Github search.
This Week’s Widget -
d3treeR was released last week in the post Week 28 | d3treeR. We’ll do
d3treeR again but we’ll make a version 2
d3tree2 using the versions from Mike Bostock’s Zoomable Treemaps and Zan Armstrong’s fork Zoomable Treemaps with Color.
d3treeR is not yet on CRAN and won’t be unless someone asks, so for now please install with
devtools::install_github. If you installed last week, you’ll need to do this again.
# we'll need the newest data.tree devtools::install_github("gluc/data.tree") devtools::install_github("timelyportfolio/d3treeR")
Let’s look at the differences between
d3tree2 in the examples below. We’ll use the same examples as last week.
treemap as data
As stated in the introduction,
d3treeR is built to work seamlessly with
treemaps from the
R treemap package.
# devtools::install_github("timelyportfolio/d3treeR") library(treemap) library(d3treeR) # first example from ?treemap data(GNI2010) tm <- treemap( GNI2010, index=c("continent", "iso3"), vSize="population", vColor="GNI", type="value" ) d3tree( tm,rootname = "World" ) d3tree2( tm,rootname = "World" )
# devtools::install_github("timelyportfolio/d3treeR") library(treemap) library(d3treeR) # last example from ?treemap data(business) business$employees.growth <- business$employees - business$employees.prev tm <- # Brewer's Red-White-Grey palette reversed with predefined range treemap(business, index=c("NACE1", "NACE2"), vSize="employees", vColor="employees.growth", type="value", palette="-RdGy", range=c(-30000,30000)) d3tree( tm, rootname = "World" ) d3tree2( tm, rootname = "World" )
