igraph node placement
...sers, I've just defended my PhD dissertation, and I'm engaging in discussions with the "ruler lady". She has some problems with my figures. The problem is that my nodes overlap the text that I've put inside of them. Here is a url for the figure: https://www.msu.edu/~wolfste4/igraph/sorter34_graphvfr.pdf (As you can see, the cluster at the center left of this graph is quite problematic.) Also, I've got a file with the weighted adjacency matrix in it here: https://www.msu.edu/~wolfste4/igraph/sorter34 This is the code that I'm using to make the graph:...

Mac Text editors
Hi everyone, I've recently moved from using a windows machine to a Mac (some might call it an upgrade, others not?I'll let you be the judge). Once I started using Notepad ++ on my windows machine, I really began to like it. Unfortunately, I'm not sure what the free text editor options are for the Mac (Notepad ++ is windows only). I've dabbled with Linux before and used

packages which call functions which run C code...
I am looking at the function ks.test in the stats package and trying to figure out why it gives a different result for a p-value than does the corresponding function in MATLAB. I am hoping for one of two responses: 1. You know about ks.tests and have a familiarity with both the R and MATLAB algorithms and can tell me why this should be happening. 2. You know where I can find the

plot.igraph
I am having trouble plotting one of my graphs (think graph theory graph with edges and vertices, not scatterplots or histograms). For some pairs of vertices, I want multiple edges to be visible in my graph. As an example of this, in my script below, I want two edges to be visible from vertex 1 and vertex 9 (among some others) yet when I plot it, only one edge is visible.

Help with card-sorting experiment
This is the first time that I've posted to this list, so if I'm doing something wrong, please let me know. Also, if there is a searchable forum where I can find help, that would be good too. I'm doing a card sorting experiment, and I'm having problems imputing my data into R for later analysis. This is what I get from each sorter: Category Name Card numbers

Adjusted Rand Index
I'm attempting to use the Adjusted Rand Index to compare different categorizations in my card-sorting experiment. However, as I am attempting to replicate a prior study, I am allowing them to put a single card in multiple piles. However, in the original paper, it looks like Rand expects the cards to be placed into "disjoint" sets. I'm wondering if there is a workaround to this

source, echo...and clicking the mouse
I'm attempting to view the progress of a script that I call on my screen as follows: source("myscript.R", echo=TRUE) When it is running, I have to click my mouse in the GUI window for anything to show up. I am wondering if I can change something so that it writes to my GUI window automatically. I've been trying to work through the documentation for the source

Heatmap fidelity
I'm having a problem when using heatmap. Even though the diagonal of my matrix is all the same value, the diagonal of my heatmap is not all the same color. Any suggestions? Here is some reproducible code: ######################################### # Get data nba <- read.csv("http://datasets.flowingdata.com/ppg2008.csv", sep=",") # Reorder nba <-

Simple question
I am trying to convert a string to a vector, and I'm stuck! Suppose you have a string of numbers (string) that you want to convert to a vector (vec). I am able to split the string turning it into a list by using strsplit, but this makes a list, which I can't seem to access the way that I'd like to (it becomes a character list of only one(?!?) element.)
