similar to: How to custom colorscale in treemap

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, they won't

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 algorithms for deciding how to place the rectangles, ref:

Hi there, I am trying to interface c++ code in R and make a package. With R CMD SHLIB the dll was created, but when I try R CMD check, I am getting 'undefined reference to..' linkage error messages. The relevant c++ source from conf-infomap.cpp: #include "conf-infomap.h" #include "R.h" // R functions #include "Rinternals.h" #include "Rmath.h" //

Hi all, I am running R 2.5.0 under Windows XP Media Center Edition. Here's a problem that's been stumping me for a few days now, and I can't find anything useful in the archives. I am using voronoi.mosaic (tripack package) to create proximity polygons for a study of vegetation competition and dynamics. The points lists are read in from a file for each plot, then 8 duplicates

Let's say I have data in the following schema that describes the number of purchases a company has received from each County in the US: State | County | Purchases --------------------------------------- NJ | Mercer | 550 CA | Orange | 23 .... I would like to visualize what states contribute the most to the overall total, and furthermore within those states, what Counties contribute the most.

Hi, Would like to make an image however the values in z are not on an uniform grid. Have a dataset with length(x) == length(y) == length(z) x[1],y[1] gives the position of z[1] and would like to encode value of z by a color. looking for something like plot(x,y, col = z) where col for z is cleverly chosen from a colorscale. Hope I made clear what I am looking for. Thanks Eryk

I can save to png, TIFF and jpg but get an error "Error: invalid graphics state" when trying to save as pdf and I have to restart R. This happens when I add mtext lines. There are a few other questions e.g. I want to move the mtext on side 1 to the left, but that is the main issue for now. I'm not using the ylab inside gplot.hexbin because it writes over the numbers on the axis.

Hi, I have a data set with 1000 observations and 260 predictors. The predictor variables are all ordinal. There are 2 classes labeled as, F 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

I have a couple of packages that use the d3.js library developed (and copyrighted) by Mike Bostock. One package uses it extensively, another only for one function. I use R to piece together parts files containing JavaScript that I have written, which use d3.js functions and eventually the d3 library is called from a temporary web page. To date, I have pointed to Bostock's library in the Rd

This sounds possibly problematic to me. The IR should be created with the correct address space to begin with. Changing this in the middle sounds suspect. > After this

I'm very new to R and I live in Mali, west Africa. I'm on *OS X 10.7.5*. I downloaded and installed *R 3.2.1*. I downloaded and installed *RStudio 00.99.893*. I ran through the free Microsoft data camp intro to R course, then started another free course through 'edX', for Data and Statistics for Life Sciences, using R. The first prompt in the course is to

Hello, Yes? Where is allActive defined, I couldn't find it. Basically, a BB is control divergent if it's execution depends on a branch that itself depends on a divergent ssa value.

*Hi, I am considering a language extension to Clang for optimizing GPU programs. This extension will allow the compiler to use different optimization strategies for divergent and non-divergent branches (to be explained below). We have observed significant performance gain by leveraging this proposed extension, so I want to discuss it here to see how the community likes/dislikes the idea. I will

Hello, It seems to me that our current DivergenceAnalysis does not save which BasicBlocks may suffer from divergent control. Am I correct? I want to modify our DivergenceAnalysis to add a "bool isControlDivergent(BasicBlock*) const" method and save in the divergence propagator the basicblock that are divergent. I am not sure that is entirely correct, if you have input on that please

In our experience, as Owen also suggests, a pragma or a language extension can be avoided by a combination of static and dynamic analysis. We prefer this approach in our compiler ;) Regards, Vinod On Sat, Jan 24, 2015 at 12:09 AM, Owen Anderson <resistor at mac.com> wrote: > Hi Jingyue, > > Have you considered using dynamic uniformity checks?

I write about R every weekday at the Revolutions blog: http://blog.revolution-computing.com and every month I post a summary of articles from the previous month of particular interest to readers of r-help. http://bit.ly/9GoTVd announced the availability on YouTube of "What is R", a 4-part video based on a recent webcast I hosted. http://bit.ly/bVSSaH announced a webinar I hosted on

Hi Owen and Vinod, Thanks for sharing the paper! I like the idea a lot. Regarding the paper itself, Vinod, are the consensual branches (e.g., cbranch.ifnone) you mentioned in the paper publicly available in PTX ISA? Owen, could you explain more on the approach of using branch-if-none instructions in your mind? I believe you have lots of great insights, but I don't see how cbranch.ifnone

I have R version 2.9.1 on my computer and the anlaysis is not working because I need to update to R version 2.12.0 the latest release. The person incharge of IT tried to download R version 2.12.0 but .exe file referenced in install isn't there - What might we be doing wrong? We have downloaded as tar.gz, uncompress then look for .exe file but not present. Many thanks, Morris
