Given two numeric vectors of possibly unequal length, I'd like to pair each element of the shorter vector with an element of the longer vector such that the sum of squared differences between the pairs is minimized. Can someone point me to an R function or an algorithm for accomplishing this? All the best, Tom Thomas S. Dye, Ph.D. T. S. Dye & Colleagues, Archaeologists, Inc.

Aloha all, I have an adjacency matrix for an acyclic digraph that contains transitive relations, e.g. (u,v), (v,w), (u,w). I want a DAG with only intransitive relations. Can someone point me to an R function that will take my adjacency matrix and give me back one with only intransitive relations? In the example, I'd like to get rid of (u,w) and keep (u,v) and (v,w). All the best, Tom --

Hello, Is it possible to extend the R lexer/parser to include multiline comments like /* acomment */ ? This way I can integrate emacs org-mode with my R code, so that I can have a table of contents, section folding, html-output of source etc. e.g /* * Display Code */ #+BEGIN_SRC R foo <- function(...){ stuff } #+end_src and so on . Thanks Saptarshi

Aloha all, I have a data frame with 4 columns. The first three are factors (f1, f2, f3) and the fourth is numeric. I'd like to explore these data using median polish. To do that I plan to use medpolish() on the matrix[f1,f2xf3], then medpolish on the resulting matrix[f2,f3]. This approach is described by Cook on page 141 of Exploring Data Tables, Trends, and Shapes. split()

Hi all, I am taking this over from r-help (see http://permalink.gmane.org/gmane.comp.lang.r.general/273985). I experience a segfault when calling gplots::heatmap.2(), but only when certain other packages are loaded. I am not sure for the correct place to send this bug report. Should I send it to the package maintainers directly? If R-help is the wrong place, please feel free to direct me to

Hi all, Please let me know if this isn't the correct place to report bugs in contributed code. Otherwise, the following code contains one additional line and a short comment above it. The extra line of code catches the unusual situation where a data column contains all 0 values. The corrected code is below the signature. Thanks for your help. Tom Thomas S. Dye, Ph.D.

Dear R users, First just want to say thank you to all for developing such a wonderful software and packages. I need to produce a wind rose plot. Tried with packages circular and plotrix and couldn't quite get what I want. Moved to package ggplot2 and it's going great. However stuck in how to move axis labels. I am using the wind rose from the help to learn how to do what I need (code

Hello R-users, I am currently trying to learn how to use the function gls of the nlme library. I fitted the following model: Generalized least squares fit by REML Model: response ~ array + dye + genes + variety + variety * genes + array * genes + dye * genes Data: data I have 11 arrays, 2 dyes, 2 varieties, 3200 genes, and 2 replications for each. Therefore I should have the corresponding

In a OpenOffice.org forum someone was asking if the spreadsheet could graph this http://www.elmundo.es/elmundosalud/documentos/2011/06/leche.html I didn't think it could. :) I don't think I've ever seen exactly this layout. Does anyone know if there is anything in R that does a graph like this or that can be adapted to do it. Unfortunately my Spanish is non-existent so I am not

Thanks to Joshua Wiley for turning me on to ggplot2. I am making a plot using this: p <- ggplot(dallas, aes(x = offense_hour)) + geom_bar() + coord_polar() Dallas is a data frame, and offense_hour is a column with chron objects from the chron library. In this case, the chron object was created with the times function. It is only a time (H:M:S) with no date attached. The plot shows up fine,

In the API docs I found this: "You can also build forms using a customized FormBuilder class. Subclass FormBuilder and override or define some more helpers, then use your custom builder " I couldn''t find any further documentation on this. Where can I read more about this formbuilder class? For starters, where would I define a subclass of this class? TIA, Jeroen --

Dear R gurus - consider this plot: library(ggplot2) dat <- sample(1:8,100,replace=TRUE) smp <- ggplot(data.frame(dat), aes(x=factor(dat),fill=factor(dat))) + geom_bar(width=1) smp + coord_polar() Q1. How do I change the font size and weight of bar labels (1,2,3...)? I've been wallowing in the 'Themes' structure and I just can't figure out the correct place to change

I am trying to draw a polar plot, which is easy enough to do in the plotrix package through the polar.plot function. However I would like to change the origin of the length vector. For instance all my length values are between 75 and 85, so instead of having the origin as 0 (the default) I'd like it to be, say, 50. Is there any way do to this in the polar.plot function, or if not is there an
