Dear all I am using color2D.maplot to map some matrixes to plot. everything works fine. It seems that when my matrix contains only the same value color2D.maplot returns the following error: color2D.matplot(estimatedsr,redrange=c(0,1),greenrange=c(0,.5),bluerange=c(0,.5),xlab="x",ylab="y",main=sprintf('Estimated'),show.legend=TRUE,show.values=TRUE) Error in rgb(reds,

Dear R users, I'm interested in a combination of a scatterplot and an image graph. I have two large vectors. Because in the scatterplot some areas are sparsely and others densely populated, I want to see the points, and I also want their color to be changed based on their density (similar to a heat map). Is there a function that can do that? Thank you, b.

Hi, This is a simple version of something that I am trying to do. If I can sort the problem basically, I figure I should be able to sort it for the program I'm writing (which would take longer to explain). I need to know if there is any way of using different colours for different intervals of a line on a graph. Eg. If I plot the line y=x for x=1:10, and split this line into 106 intervals

Hi, I do not have much R experience just the basics, so please excuse any obvious questions. I would like to create bubble plot that have Categorical data on the x and y axis and then the diameter if the bubble the value related to x and y. Attached to the email is a pic of what I would like to do. I do hope someone can help me. -- Regards/Groete/Mit freundlichen Gr??en/recuerdos/meilleures

Hi all, plotrix 3.2 has arrived. The reason for this announcement is that there have been a couple of major rewrites. The barNest family of functions has had an overhaul that began as a fix for an apparently trivial bug that caused problems with empty subcategories. So far, testing has not found anything that will break code written for the former version. color.scale will now convert

Considering the R function/plot shown below, I wonder whether it is possible to do the following changes: (1) Change the color of each point to be picked from list of colors according to its z-value. (The range should be from blue (z=0) to red (z=1).) The grid should then be omitted. [I have seen "terrain.colors", but don't know how to use it for this purpose.] (2) Add two lines to

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) :

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]]

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

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)

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.

I am a true R novice aonly using it for this function ;) I am trying to use color2D.matplot to form a image of my data using the following conditions color2D.matplot(fi1, c(dr), c(dg), c(db), nslices=7, ylab='Species', xlab="gene", show.legend=TRUE) where fi1 is my matrix. I have a matrix with 36 columns and 130 rows. most entries are 1 or 0 and I am trying to get this

I'm trying to follow the ggplot introduction here: http://had.co.nz/ggplot/ggplot-introduction.pdf I've installed ggplot2 with install.packages("ggplot2", dep=T) but when I try to run print(ggpoint(p, list(colour = sex))) I get an error: Error in print(ggpoint(p, list(colour = sex))) : could not find function "ggpoint" What is the problem? Has the function been

I have an application I wish to install under WINE on Ubuntu 10.04 LTS It uses a parallel port Rainbow (sentinel) Hardware key (dongle) I have searched and found a few threads that discuss these devices and a few claims that they have been made too work, but I haven't found a clear explanation of how what is necessary to get it to work. -- Rob

Hello, I have created a 3d scatter plot using the plot3d command in the rgl package. I have approximately 6500 data points in the scatter plot. I would like to color these points sequentially using the entire color spectrum. (So the first point is red, next point slightly different, and each point gradually changes so that the final point is violet.) Is anyone familiar with how this can be done?

Dear R colleagues, I am trying to create a new column in a data frame, which converts values and NA's from another column into binary format. Essentially I need the NA's to become 1 and the rest to be 0. The code I wrote is returning the following error message: Error in if (mort[i, 4] != NA) mort[i, 8] <- 0 else if (mort[i, 4] == : missing value where TRUE/FALSE needed

I have followed the instructions on how to build a Windows package and everything seems to work EXCEPT that I can't see the data files that I have loaded into the data directory. I have placed the appropriate data in the data directory (as in the instructions). There are 3 data sets, which I can see when I use the command in R. Details below. I have searched everywhere to try to fix this, but

Hi Tinc Mailing-Group, Having set up the kernel correctly, and got tinc running successfully, I am now trying to get two VPNs running at once. Hence I need to have two ethertap devices ( /dev/tap0 and /dev/tap1 ). The first tap0 device was created thus: mknod -m 600 /dev/tap0 c 36 16 chown 0.0 /dev/tap0 The second tap1 device was created too: mknod -m 600 /dev/tap1 c 36 17 chown 0.0 /dev/tap1

We work on a secure stand-alone server with no internet access, for security reasons. We are running Windows XP. SInce version 2.11 the R help files point straight to the internet. Is there any way we could have a local help that we could access on our server. Thanks in advance for any solutions Gillian Raab
