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.
Regards,
George

How do I ensure that the minimum value is always displayed on a y-axis in a plot?
Good day all,
I'm trying to plot a figure and ensure that the minimum and maximum
values are always displayed. However, the code below does not display
the minimum value, no matter what I try. Could someone please help?
Thanking you in advance,
George.

How do I plot a line followed by two forecast points?
Good day all,
I'm trying to plot a continuous line plot, which is followed by two
forecast points eg. one forecast point is 12 months out, and another
24 months out from the last date of the line plot.
In my attempts so far, the second plot (the forecast points) is scaled
against a new axis scale, thus the two plots are not directly
comparable (I need the forecast points to be scaled

How do I plot: regression line, regression line + s.d, regression line - s.d on the same chart?
Hello all,
I've got a scatter plot, for which I create a regression line using:
reg<- lm(yvars~xvars) and can plot the regression through the scatter
just fine.
I'd like to add two additional lines on the scatter plot: one being
regressionline+standard deviation, the other being
regressionline-standard deviation, thus creating some kind of 'band'
for the scatter.
Any help will

Has any one tested R 2.9.2 on Snow Leopard?
Hi all, not sure if this is the right place to ask this but R not
being such a "mainstream" app, can't find the answer anywhere. I plan
to upgrade to Snow asap and just wondering if anyone else has already
and has successfully used R on Mac OSX 10.6. If so, what version? and
is it running in 64 bit mode?
Thanks in advance,
George.

Is there a way to round numbers up or down to the nearest "natural looking" number?
Hi all,
Given the following series of numbers:
> t
[1] 21.85000 30.90410 43.71000 61.82234 87.43999 123.67296
[7] 174.91997 247.40249 349.91996 494.91815 700.00000
What's the simplest way of formatting them into the nearest "natural
looking" (rounded to nearest multiple of 10) numbers?
So:
t[1] becomes 20
t[2] becomes 30
t[3] becomes 40
t[4] becomes 60
t[5] becomes 90

Can someone please explain why the last tick mark on this chart is not showing?
Hi all,
I'm trying to log chart but with natural looking tick marks. My
specifications are very specific -- it must indicate the lowest
number's tick as well as the maximum.
I've attached sample code and data for a particular case (and there
are a few more like this) where the bottom tickmarks on the chart are
not set to where I want them to be and yet they fit in the ylim range.
