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 <- color.scale(...

...olour 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 obviously, but there's a different number of events for each loco and what I would like to do is to use rainbow to create a new palette for each graph To illustrate I have some model code (made-up and v simplified) Real times are not necessarily whole numbers so there's not a one to one correspondence between times and index of time elements sec.time<-seq(0,100) distance<-c(rep(0, 10),rep(1,5...

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, gam...

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

...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...

Hello I'm using rainbow function to generate 10 colors for the plot and it is difficult to tell the neighboring colors from each other. How can I make the colors more differently. Thanks Zhaoming [[alternative HTML version deleted]]

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 for the second level. What I want to do is change the symbols so they all plot as circles, then change the colours used to plot each factor level (e.g...

Dear all, Can you pl. help me in plotting a matrix into 2D plot with more color options. I tried to plot with myImagePlot with RGB color ramp but it shows limited variation in color. There is a rainbow plot option also. Can anyone help me.

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...

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 performanc...
