Treemaps
Has anyone implemented "treemaps" in R?
A "treemap" is a visual display of a tree structure in which, at each level,
the several nodes are represented by rectangles which fill the available area.
The areas of the rectangles represent size, and their colors represent some
other variable. There are several algorith...

Treemap lost data
First: Im sorry for my bad english ;-)
I use "portfolio" to create treemaps with "R".
I've got a .csv dataset of all the schools in my city, containing 6
variables each with 1469 lines of data.
When I create a treemap, 3 of these schools were not taken into account by
"R". I dont know why. It doesn't matter where I put them in my dataset, the...

How to custom colorscale in treemap
...0(Green)-1(Red)-max(green). What's the easiest way to
achieve this kind of divergent color scale?
How shall I make my own palette and use it in the map.market or tree map
function?
Thank you very much~

Recommended visualization for hierarchical data

NJ | Mercer | 550

I would like to visualize what states contribute the most to the overall
total, and furthermore within those states, what Counties contribute the
most. What are some recommended R visualizations for this type of data? I
created a treemap using map.market from the portfolio library, like the
following:

Although this is an attractive visual, I want something that makes it easier
to compare the relative sizes of components at a glance (hard with a treemap

Heat Maps
Dear List,
Does there exist a function that produces a heat map like this one

2. Mose-over capability.

squared "pie chart" - is there such a thing?
Hello!
It's a shoot in the dark, but I'll try. If one has a total of 100
(e.g., %), and three components of the total, e.g.,
mytotal=data.frame(x=50,y=30,z=20), - one could build a pie chart with
3 sectors representing x, y, and z according to their proportions in
the total.
I am wondering if it's possible to build something very similar, but
not on a circle but in a square - such that

Problem installing/loading packages from Africa
...So RStudio tells me that the packages are
available to load, BUT:
- when *loading* any package an error comes up saying package 'name of
package' was built under R version 3.2.5 but info on swirl says it should
work on any version of R above 3.0.2. I get similar errors for other
packages (treemap, ggplot2, etc).

RandomForest
Hello,
When I plot or look at the error rate vector for a random forest
(rf$err.rate) it looks like a descending function except for a few first
points of the vector with error rates values lower(sometimes much lower)
than the general level of error rates for a forest with such number of trees
when the error rates stop descending. Does it mean that there is a tree(s)

Proper attribution in Authors@R for the d3.js library by Mike Bostock
...number of packages that use d3.js now, and the habit (standard?) now seems to be to put Bostock in Authors at R, but they do so in different ways. Here are a few examples:
D3partitionR: Mike Bostock [aut, cph] (d3.js library in htmlwidgets/lib, http://d3js.org. The partitionChart, sunburst, the treemap, the zoomable circlePacking, the collapsible indented tree and the collapsible tree are all derived from his works.)

...and T with class proportions of 0.44 and 0.56, respectively.
In a call to the function randomForest() with mytry=1 and nodesize=1 and
ntree=100 the resulting classifier puts all observations in class T.
When I change nodesize to nodesize=5 I get the following error message:
Error in array(rfout$treemap, dim = c(2, nrnodes, ntree)) :
dim<- length of dims do not match the length of object
Higher values of nodesize also result in this error message but values
of nodesize less than 5 do not.

Combined Marimekko/heatmap
Hi all,
I'm trying to figure out a way to create a data graphic that I haven't ever seen an example of before, but hopefully there's an R package out there for it. The idea is to essentially create a heatmap, but to allow each column and/or row to be a different width, rather than having uniform column and row height. This is sort of like a Marimekko chart in appearance, except that

rpart vs. randomForest
Greetings. I'm trying to determine whether to use rpart or randomForest
for a classification tree. Has anybody tested efficacy formally? I've
run both and the confusion matrix for rf beats rpart. I've looking at
the rf help page and am unable to figure out how to extract the tree.
But more than that I'm looking for a more comprehensive user's guide
