creating rainbow gradients
Hi, how can I create a rainbow gradient in R? For example, let's say I have a plot of y = x...and I want the plot to go from red -> orange -> yellow -> green -> blue -> etc. Right now, I know how to do something like go from red to blue, using the plotrix library: library(plotrix) redToBlue <-

Rainbow in loop
Hi R folk I have a distance time graph for a locomotive and at various times different events occur on board the loco. I want to put a vertical line on the speed time graph for each event, but I want to colour each different kind of event differently to see visually whether there's any pattern to these events happening. I could just create a vector of colours and use abline which is easy

How to use rainbow function without the gamma argument
Hi, I am using a old code (probably written for R 2.5) and it stops when calling rainbow() with gamma argument. I saw that gamma argument is not present in newer version of R rainbow function. How can I translate this line of code: rainbow(100, s = 1.0, v = 0.75, start = 0.0, end = 0.75, gamma = 1.5) ? It fails with: Error in rainbow(100, s = 1, v = 0.75, start = 0, end = 0.75, gamma = 1.5) :

repeating colors in graph 2
I've tried looking at ?colors and ?palette and if I'm understanding it correctly, I'm supposed to type in (for example) palette(rainbow(13)) before I type in my plot (of 13 lines) if I want 13 different colors. But this does not work. Other things that i have tried besides rainbow give me errors. Am I just doing something completely wrong? Anna

Rainbows! or unicorn?
...tting together a small web frontend for a client to upload files into an existing application. It''s trivial - there will never be more than a (small) handful of concurrent connections, but I need a streaming rack.input for upload progress on files up to 500MB or so. I was planning on using Rainbows! with ThreadSpawn and worker_connections=1, then noticed that unicorn is also listed as having streaming rack.input. While what I''m doing is pretty much the opposite of the unicorn design case, is there any reason in this scenario for me to use Rainbows!, or should I just go with unicorn...

cbind() and factors.
Hi I'm seeing some "odd" behaviour with cbind(). My code is: > cat <- read.table("cogs_category.txt", sep="\t", header=TRUE, quote=NULL, colClasses="character") > colnames(cat) [1] "Code" "Description" > is.factor(cat$Code) [1] FALSE > is.factor(cat$Description) [1] FALSE > is.factor(rainbow(nrow(cat))) [1]

Assign palette (e.g. rainbow) to a series of points on 1 plot
I have 11 vectors representing insect survival probabilities in response to different levels of toxins at 10 concentrations lx100=c(1,1,1,.8,.5,.4,.2,0) day100=c(0,1,2,3,4,5,6,7,8) lx90=c(1,1,1,1,.9,.8,.6,.4,.2,.1,0) day90=c(0,1,2,3,4,5,6,7,8,9,10) #...and so on10% and a zero (control) series lx0=c(1,1,1,1,1,1,.9,.9,.8,.8,.6,.5,.4,.3,.2,.1,.1,0)

ordisymbol - changing symbols used in plotting factor levels
Hello, I'm trying plot points in an NMDS according to a factor with two levels: fig<-ordiplot(canod.sol, type="none",cex.axis=0.9,cex.lab=0.1,pty="m",tck=-0.01) ordisymbol(fig, y = hab, factor = "habitat", rainbow = T,col = env, legend = F) This gets me part of the way - It produces a plot with blue triangles for the first factor level and red circles

Rainbows...
Some of you may have noticed the "rainbows" branch of the git repository. I may be changing that however and making a small group of gems (or even one gem) that can get loaded at runtime and monkey patch parts of Unicorn. Rainbows will primarily be to support things Unicorn sucks at: 1. apps that rely on out-of-datacenter network...

formatR: farewell to ugly R code
This is an announcement of the release of an R package 'formatR', which can help us format our R code to make it more human-readable. If you have ugly (I mean unformatted) R code like this: ?# rotation of the word "Animation" # in a loop; change the angle and color # step by step for (i in 1:360) { ? # redraw the plot again and again

pixmapIndexed color question
Hi I use pixmapIndexed tmp.vimp <- array(0,c(x.dim,y.dim)) tmp.vimp <- pixmapIndexed(tmp.vimp, col=rainbow) to plot values of a 2D matrix. I 'fill' the pixmapIndexed like: for (x in 1:x.dim) { for (y in 1:y.dim) { tmp.vimp at index[x,y] <- my.matrix[x,y] }} how can I define, that the colors are painted e.g. according the rainbow

Given the use of random salts, you would have to generate (number of possible salts) rainbow tables. This drastically changes the CPU/storage tradeoffs. >

kgio library / RubyGem
Hello all, I''ve released kgio, a kinder, gentler I/O library for Ruby. Some of its features are useful for Unicorn, and all of it is useful for Rainbows! I intend to make kgio a requirement for both Unicorn and Rainbows!/Zbatery. I''m comfortable with the code, but extra testers and extra eyes to review it would be helpful (it''s nearly all C). There were several factors leading the creation of this library: 1. The performance...
