pre summary: mapping of colornames into hsv?
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

mapping of colornames into hsv?
I couldn't find this in online help or the archives:
Is there any R function or object giving the mapping of the colornames as
given by colors() into the hsv() model?
Regards

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

hsv producing a color intensity not in [0,1] (PR#2576)
Full_Name: Jae Choi
Version: 1.6.1
OS: linux (x86)
Submission from: (NULL) (142.176.61.245)
Hello,
Any attempts to access the "hsv" function returns the following type of error:
Error in hsv(h = seq(start, ifelse(start > end, 1, 0) + end, length = n)%%1, :
color intensity 1.25, not in [0,1]

Bug in hsv() (PR#712)
Ross posted this code:
persp(x, y, z, col = cm.colors(10)[floor(9 * hgt + 1)], theta = 35)
I hadn't seen the cm.colors function before; it's very nice! I wanted
to modify it a bit to allow the start and end colors as well as the
max saturation to be specified, and I think I may have turned up a bug
in the hsv() function. Here's the evidence of the bug:

incomplete final line found on <name of my sourced function file>
Dear R-ers,
I hope there is a really simple solution to my problem.
I've written a function that I saved in an .r file. I source this file
in my code. For a while it worked fine. But then when I run the line:
source("F mylineplot.r")
I started getting a warning:
In readLines(file) : incomplete final line found on 'F mylineplot.r'
I have no idea why - I tried to check and

Question about legend parameters
Hello!
The code below works - if you run it you'll see a stacked area chart
generated based on the data example.
I only have one understanding question about the legend location (the
very last snippet of code):
legend(par()$usr[2],
mean(par()$usr[3:4]),
rev(order.of.vars),
xpd=T,
bty="n",
pch=15,
col=all.colors[rev(order.of.colors)])
I see that par()$usr[2] = 14763.72

making scatter plot points fill semi-transparent
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

Recommendations on intrusion prevention/detection?
Dear all,
what are the key strategies for intrusion prevention and detection with
dovecot, apart from installing fail2ban?
It is a pity that the IMAP protocol does not support 2 factor
authentication, which seems to stop 90% of intrusion attempts in their
tracks. Without it, if someone has obtained your password and reads your
mail without modifying it, you will hardly ever notice.
Is there a

3D package in R
Hi all,
I am considering writing a 3D visualisation package for R.
Purposes:
- Visualise 3 dimension data
- Manipulate the data or series or any other object with the mouse as in any 3D software (3D Studio Max, Lightwave...)
- Eventually display more than just 3D objects.
Justification:
- It's always interesting to plot data before performing any analysis
- Manipulating (rotating,
