I was probably a bit obscure and should have written "convert your
0-255 values to 0-1". As Bert notes, you can't get a sensible ternary
plot if your values do not sum to 1. scatterplot3d does a pretty good
job, if you run the example.

Hi,
When using the geom_ribbon function in gglot2 package, I got the text
"fill" above the legend "A" and "B". How can I get rid of the text "fill"
above the legend?
Thanks!
The code is as follows:
df<-data.frame(x=c(1,2), y=c(1,2), z=c(3,5))
> ggplot(df,
aes(1:2))+geom_ribbon(aes(ymin=0
3-d Proportions must sum to 1and are thus actually 2-d and should preferaby
be plotted as a ternary plot. Several r packages will do this for you, e.g.
package Ternary. Search "ternary plots" on rseek.org for others.

... Perhaps worth adding is the use of poly() rather than separately
created terms for (non/orthogonal) polynomials:
lm(y ~ poly(x, degree =2) #orthogonal polyomial of degree 2
see ?poly for details.

Richard,
It is now working.
Thank you very much.

Hi Tasha,
I may be right off the track, but you could plot RGB proportions on a
3D plot. The easiest way I can think if would be to convert your 0-255
values to proportions:
rgb_prop<-read.table(text="Red Green Blue pct
249 158 37 56.311
249 158 68 4.319
249 158 98 0.058
249 128 7 13.965
249 128 3
I can't figure out what message you are hoping to convey in your plot from your

Hello,
You are calling plot.default with 4 arguments.
The first 2 are x and y.
The 3rd is type.
So MyData$NWorthSm becomes the 4th, xlim.
When you pass xlim a value, MyData$NWorthSm becomes the next one, ylim.
Etc, etc, etc.
It will throw the errors in the order of the arguments you can see in
Dear Eric, Ivan & Rui
Thanks all for your suggestions. FWIW, I've opted to use paste0 and
after a bit of playing around found it formatted the output nicely.
Eric, I wasn't aware of sprintf - seems a handy function to format text
with, so will try to remember that.
Ivan, I'll dig into 'messa
Dear Bob
We do not have your data so it is hard to be sure but plot() takes two
parameters for the data x and y so when you give it three you are
confusing it into thinking one of them is something else.
What exactly were you trying to do with the failed command?

Hi Subhamitra,
My apologies, I caught a mistake. To have the first tick in the middle of
the first year, you want half of the _observations_ in a year, not half of
the days. As I now have your data at my fingertips:

Almost exactly what was calculated for the first serie

I often use sprintf() to control formatting of text strings. e.g.
sprintf("%s is not between 1 or 15\n",nums)
See ?sprintf for details
