Confused about specifying plot colors as RGB values
Based on reading 'rgb' documentation, I would have thought
the following would have produced identical results. Can
someone explain how to make this happen? I need to be able
to specify an array of rgb values for the 'col' parameter.
colnames.col <- c("black", "red", "blue", "green")
colnames.rgb <- apply(as.matrix(colnames.col), 1,

RGB components of plot() colours
A quick question:
Is there anywhere a listing of the RGB components of the
named colours listed by colors()?
For example, where would I find the RGB for "orange1"
or "salmon"?
When I look at an EPS file from R where I have used
these colours, it seems that for:
"salmon":
0.9804 0.5020 0.4471 rgb
"orange1":
1 0.6471 0 rgb
However, this is a tedious way

alpha parameter in function rgb to specify color
Hi All, 
In function "rgb", alpha parameter is supposed to set
the transparency value. But in my following two
examples, it didn't work:
plot(1,col = rgb(1,0,0,alpha =0.8))
# as long as alpha < 1, there is no point in the plot.
plot(1,col = rgb(0,0,255, alpha=254,
maxColorValue=255))
# as long as alpha < 255, there is no point in the
plot. 
Do I use it in the right way? Any

Converting RGB YUV and back
Hi all,
how can I convert a RGB (24 or 32) image I'm getting from a webcam for
example to YUV to compress it with theora, decompress it and convert it back
to RGB to draw it?
Any suggestions?
Best regards,

Re: YUV to RGB
Mike Melanson: I want to store RGB values instead of YUV. I don't understand the theoretical and practical implications of this and that's why I'm asking about it. I would like to know whether it cannot work and why.

RGB function
Hi all,
I created three separate square matrices (lets say R, G, and B).  each
one contains a series of values between 0 and 1.  I want to be able to
take for example R[1], G[1], B[1] and create a rgb color value into a
fourth matrix.  I tried using the rgb function but I must be doing
something wrong because it fails with the following error message.

Is there a way to convert rgb/hex value to a (nearest) color name?
Hi all, I'm trying to convert a series of rgb codes into a color name.
What is my easiest option? So far I'm stuck with just converting to
hex using rgb() and I know R knows a number of colours() but a mapping
of the two has failed me.
Any help in this regard will be highly appreciated.

Colour to RGB value?
There are a lot of ways to specify colours in R plot functions (number
from the palette, by name, etc.).  I'd like to pass a colour from an R
function to an external function, and I'd like it to have the same
flexibility.  To avoid having to interpret all possible colour
specifications myself, I need a function to convert a general colour
specification into a standard form (e.g. r,g,b

Hello, i'm sorry for my English is not good.
I need help with convert yuv_buffer data (YCbCr) to RGB without SDL.
I write:
