How to do rotation for polygon?
Hi everyone, I have coding for repeating pentagon as below: plot(0:11,type="n") for (i in 1:10 )polygon(rep(c(4,5,7,8,6)), i*c(.5,.3,.3,.5,.7), bor=2) which are increasing vertically. Now, I want to know how to rotate the pentagon, so that I will get pattern like flower. Basicly, repeating pentagon in circle. Thanks alot for helping me to solve this problem. -- Hemavathi

Merge data frame and keep unmatched
Hi, With two data sets, one complete and another one partial, I would like to merge them and keep the unmatched lines. The problem is that merge() dosen't keep the unmatched lines. Is there another function that I could use to merge the data frames. Example: completedf <- expand.grid(alpha=letters[1:3],beta=1:3) partdf <- data.frame( alpha= c('a','a','c'),

Getting many substrings but only loading the original string one time.
Hi All, I'm looking for a way to get many substrings from a longer string and then stitch them together. But, since the longer string is really, really long (like 250 MB long), I don't want to do this in a loop and load and re-load the longer string many times. Does anybody have an idea? Maybe I could pass in two vectors (the first would have the starting coordinates, and the second

For sending my R package as part of R-project
To Whom It May Concern: I have an R package and want to put this package be part of R-project and available to anyone who is interested in. The R package is created for my paper, titled "Acceptance Sampling Plans from Truncated Life Tests Based on the Birnbaum-Saunders Distribution for Percentiles". The paper has been accepted by Communications in Statistics: Simulation and

Filled triangles in lattice graphics?
Dear R users, I can get a filled triangle pointing upwards by specifying pch=17 in xyplot or lpoints, but how do I get a filled triangle that points downwards? In the standard plot function it's possible to use plot(x,y,pch=25,bg="black"), but bg= doesn't seem to work with lattice and lpoints. Thanks, Hans Gardfjell Ecology and Environmental Science Ume?

Finding all triangles in a graph
I have the adjacency matrix of a graph. I'm trying to find all triangles (embeddings of C_3). This doesn't work: index = function(l) seq(l)[l] pairs = do.call(rbind, lapply(seq(nrow(adj)), function(x) cbind(x, index(adj[x,])))) triangles = do.call(rbind, apply(pairs, 1, function(x) cbind(x, index(adj[x[1],] & adj[x[2],])))) I'm absolutely certain I've gone down the wrong path

Tessellation shaders get MEM_OUT_OF_BOUNDS errors / missing triangles
Hello, I've been debugging a few different tessellation shader issues with nouveau, but let's start small. I see this issue on my GK208 with high frequency, and I *think* I've seen it once or twice on my GF108, but it's exceedingly rare, if it does happen. I don't have a GK10x to test on, unfortunately, but I assume it'll have the same issue as the GK208. The issue is

Tessellation shaders get MEM_OUT_OF_BOUNDS errors / missing triangles
One additional observation that I just made is that on GK208, the blob apparently doesn't use the result of S2R Rx, SR_INVOCATION_ID wholesale in TCS. It either passes it through a I2I.S32.S32 Rx, |Rx| (i.e. absolute value), or even more paradoxically, shl 2; shr 2; which removes the top *2* bits, rather than just the top 1. However I see no such behaviour on GF108. I'm going to test out

nls() and nls2() behavior?
first, apologies for so many posts yesterday and today. I am wrestling with nls() and nls2(). I have tried to whittle it down to a simple example that still has my problem, yet can be cut-and-pasted into R. here it is: library(nls2) options(digits=12); y= c(0.4334,0.3200,0.5848,0.6214,0.3890,0.5233,0.4753,0.2104,0.3240,0.2827,0.3847,0.5571,0.5432,0.1326,0.3481) x=

Scatterplot question
Dear list members, I have a probably simple question concerning scatterplots: I want to draw a plot with one X but several Y columns, so that every group of samples gets a different symbol. My table looks like this: X Y1 Y2 Y3 1 1 2 3 3 5 4 7 5 9 6 11 7 13 8 15 Simple in Excel or StarOffice, but how do I do it in R? Thanks a lot Judith

New R-Packages: Triangle and LHS
Two new packages have been added to CRAN. The first is a simple package which provides the standard functions for a triangle distribution (rtriangle, dtriangle, ptriangle, qtriangle). The second package generates and augments Latin Hypercube Samples. Functions for generating random and optimized designs are provided. I look forward hearing your feedback and improving the documentation!

lower triangle of the correlation matrix with xtable
