Hello Core Folk. Quite by accident I discovered today that col2rgb, when fed factors, acts on the integer representation of those factors: td <- as.factor(rainbow(5)) # not how I discovered the issue! td res <- col2rgb(td) res # but col2rgb("#FF0000FF") # this is td[1] but does not produce the same answer res[,1] # moreover as.integer(td) col2rgb(5) # the integer value of the

Hi Martin, Great that you follow this. My original intention was to be able to translate colornames to hsv because this would allow using colornames to cut out a certain part of the colorwheel for colorcoding (HSV component H, see my code below) I think internally we might have colors represented as Colornames, ColorIntegers, ColorHexcodes, ColorRGBs, ColorHSVs (ColorCMYs?) however the R-user

Dear List, I have a 47 species * 83 samples matrix containing percentage abundance data. I have two cluster analyses one of the samples and one of the species, and have ordered the rows and columns of the species by samples matrix according to these two cluster analyses. So far so good! Now what I want to do is create a plot with the species dendrogram at the top of the plot, the samples

I have a simple bar chart with annual precipitation (jan to dez). I want to plot, above each bar (on a line), a square wich is color based on a scale (0-100%). With 0 being white and 100 black, like a gradient. Is it possible? How to? Thanks -- Fernando Andreacci [[alternative HTML version deleted]]

Dear, I am having a lucky day. I am programming in RStudio and when I type "black" (quotation signs included, the word turn into a word with black ground. Couldn't get rid of the background----copying to Word, Excel, text editor and paste back to Rstudio, the word is still in black background? Help! ??? dv.group<-c("black","othrrace");

hi all, i have a simple scatter plot, and i'd like to make it so the scatter plot colors are slightly transparent. i see in a previous post that someone mentioned the "alpha" parameter, but i am not sure how it can be used with the 'plot' function [*]. for example, suppose i have: plot(mydata$column1, mydata$column2, col="red", cex=1) i now want to make it so

Hello, I would like to make a plot (preferably lines, but points will do too), where the line segment changes color depending on the value of the y-axis. For example, let's suppose the y-axis range is from -1 to 1. Points close to -1 would be colored blue, while points close to 1 will be colored red. Points in between will be varying degrees of blue/red depending on how close they

It appears that the chromatic adaptation feature of `grDevices::convertColor`is broken, and likely has been for many years.? While a little surprising, it is an obscure enough feature that there is some possibility this is actually broken, as opposed to user error on my part.? If it turns out to the latter, I apologize in advance for spamming this list. Consider: ??? rgb.in <-

Is there any possibility to divide too long text in a plot to two or more lines, when using labels-parameter in the text()-command? Here is an example picture: http://users.utu.fi/attenka/253.jpeg My example script is something like this: text(1,0.7,labels=Chordnames[fnid(pcs%%12)]) # according to Larry Solomon's table http://solomonsmusic.net/pcsets.htm Chordnames is a long vector with

I just wanted to add to Krzysztof's response. I'm not sure if you're referring to the case when a compile-time trip count loop is completely unrolled or for a loop with a run-time trip count, which would be partially unrolled. For Hexagon, if we partially unroll a loop, we'd also like to use our hardware loop instructions. That is, unrolling and hardware loops are

Dear R users, I want to generate two random variables (X1, X2) from uniform distribution (-0.5, 0.5) with a specified correlation coefficient r. Does anyone know how to do it in R? Many thanks! Menghui

Hi All, I was trying to templatize some JSP page I would like to dynamically generates but it looks like puppet doesn''t like it. Common JSP tags are <% ... %> so I guess it''s getting confused between regular tags and jsp''s one. This is an example of the trace it is givin me : /etc/puppet/modules/xxx/templates/webapps/xxx/yyy/Mantle.jsp:1:in `result'':

Hi, I'd like to contribute to Vorbis and I think this may be of some interest for low bitrate coding. I have been experimenting with low bit-rate coding for the high-band (11 kHz to 22 kHz) and, though I haven't yet started quantizing my coefficients (a gain and an LPC filter), I expect to be able to approximate the whole 11-22 kHz band with around 1000 bits/s per channel (maybe even 500
