similar to: R-alpha: R color problem

Greetings all, It would appear that some default behavior changes for barplot() have been introduced into Version 1.9.1 alpha (2004-05-30). One change is in the specification of the default 'col' argument, which is now: col: a vector of colors for the bars or bar components. By default, grey is used if height is a vector, and heat.colors(nrow(height)) if height is a matrix.

Dear R-help, Can some one explain why barplot() uses changing colors in the bars by default? I should think that most of the time when people draw barplots, they want the bars to be in the same color. (At least that's what I'd expect. The first time I used barplot() in R, I was shocked to see the colors.) As an example, one example in ?layout draws a scatterplot with histograms drawn

In several places, we have the convention that col = NA means `` don't draw '', e.g. for points() or rect(). For col = <vector> this only works when the vector is integer (numeric), but not in other cases. I think this is a bug, even though not in the strict sense, since we don't seem to claim it should work.. Example: plot(1:10, col = c(1:4,NA,NA,4:1)) ## fine

I want to get a lighter shade of a color...I have a lot of colored objects and want each one printed as a foreground against a slightly lighter background. I thought I could try something like changing the alpha channel by first converting it to rgb. But prior to trying that, I'm stuck with how to get the color after converting using col2rgb() to be interpreted again as a color, rather than

Hello, how can I change the color of the asterisk prompt to red ? I read in the wiki that I can use %Cn[;n] https://wiki.asterisk.org/wiki/display/AST/Asterisk+CLI+Configuration But what does this mean ? There is no example how to actually use it. where do I put it? What syntax is that anyway? How do I specify red ? I currently have this in my environment: export ASTERISK_PROMPT="[%H]:

When in VGA graphics mode, BIOS int 10h ah=09h doesn't seem to treat high-order attribute bits as a background color; instead, it apparently always uses black. This means that a background color requested via <SI> in a DISPLAY file is not honored in VGA mode. However, the BIOS supports an "XOR" mode, in which the pixels to be written are XORed with pixels already on the

Hello, I'm trying to make a 3d plot using rgl in which the size and color of each point corresponds to certain attributes of each data point. The color attribute, let's call it X, is scaled to go from 0 to 1. The rainbow(64,start=0.7,end=0.1) palette is perfect for what I want but I don't know how to take that palette and pick a color from it based on the value of X for a given data

Hello I have been playing with tcl/tk in R 2.4.0 on windows XP and have managed to crash R by supplying tcl/tk with an incorrect color. Is this a bug? is there a way for me to test the color to see if it is a valid tcl/tk color, to avoid this? tt=tktoplevel() tklabel(parent=tt, text="hello world", foreground="reed") Error in structure(.External("dotTclObjv", objv,

Hi, I'd like to construct a somewhat unusual barplot. In "barplot" I use beside=F as I'd like to have stacked bars. The height of each bar is always the same. Information in my plot is coded in the color of the bar. I therefore need to be able so assign a different combination (or order) of colors to each individual stacked bar. In the example below, the combination of

I would like to hear from some one who has ecb, multiple modes with ruby mode + html mode, rails mode all working together and playing well. I had ecb working with Ruby syntax highlighting. That was a no-brainer since I just had to apt-get them on my Debian Sarge box. It got a bit more comlex after I got most of the .el files in the articles http://www.emacswiki.org/cgi-bin/emacs/RubyOnRails

Hello R Fundi, The poetic title of this post is a request for help in regard to a "simple" plotting question. I have displayed the mean observations of a series variables using barplot(). On the same figure I have colored the bars to represent the Standard deviation of each variable using color.scale(). Now I wish to add a graduated colorbar (legend) that corresponds to the colors

In an R graphic, I'm using cond.col <- c("green", "yellow", "red") to represent a quantitative variable, where green means 'OK', yellow represents 'warning' and red represents 'danger'. Using these particular color names, in B/W, red is darkest and yellow is lightest. I'd like to find color designations to replace yellow and

Unhappily, there is no way to load these preferences back in when starting a new session. Also, the scroll window for selecting colors is very small and

Here is a proposal: At present when you specify a color with an integer it is taken as an index into a fixed table of 8 colors. 1=red, 2=green, 3=blue, 4=cyan, 5=magenta, 6=yellow, 7=white, 8=black [At least this is the intention, there may be bugs in the implementation]. Since I am looking at this anyway (to see if I can see the bug that Martin and Kurt have mentioned) I thought I might

Hi there, I trying to solve this problem for the whole day not going anywhere, so I really hope maybe somebody can help me in this community... I've got an object coefficient2 which I want to plot in differerent ways, with colors and labels added to the points, but somehow there seems to be a problem if a value is NA within the independent variable, resulting in false labels and false colors
