Hello R users,

It's easy to compute a monthly climatology (12 values), Now, I would like to
calculate the corresponding standard deviation, ie the 12 values
calculated from the january values, february values, etc.

Here is a function that does what I want in this case, and tries to do
it to work generally
with ellipse3d. (Note that I reverse the order of centre and scale
'cause I was bitten
by trying ellipse3d.axes(cov, mu))

You could always try

That is zero out the degenerate dimensions. Of course you'll be
plotting what is essentially a two dimensional object as if it were
three dimensional. The degeneracy in y

IMHO in R there is nothing to be fixed (in this regard) except your

Hi Keith,
No doubt, 7.0 is integer in math. But if people can write 7 why people
need to write 7.0 (I do not see any reason to do this). My point is
that R maybe can do something like S-plus. No point to argue. don't
you think so?
Thanks

Quoting Keith Jewell [EMAIL PROTECTED]:
I don't remember which version View was added in, but it was more recent than
2.4.1. I would suggest upgrading (2.4.1 is ancient in R terms).
You can get something similar with:
invisible(edit(mydata))
But you will have to close the window to continue with R (View lets you look at
the data
I would like to use the data below where the plots are close to what I
want. Instead of color I would like to use different symbols, and
have the symbols in the legend match the graphs. I am also going to
add a regression line to these I know about the type=r (which is
fine for these particular
Dear R People:
I finally (Yay!) got R installed in a classroom!
Anyhow, I have a respectful request, please: could anyone recommend
some nice undergrad projects in R, please?
This is in a statistical computation class; first time being run.
Thanks,
Erin

Hello,
I have been using sink to create text file outputs.
sink(summ_model1and2.txt)
summary(model1)
summary(model2)
sink()
Q1: Is there a way I could add a line of the text above the summary to act
like a title?
Also, I have been using the following to save plots from the lm function:
And here is one way of using JohnsonFit to display how a distribution changes
with changes in the moments:
library(TeachingDemos)
library(SuppDists)
tmpfun - function(m1=0,m2=1,m3=-0.2,m4=3.7, xmin=-3, xmax=3){
parms - JohnsonFit( c(m1,m2,m3,m4), 'use')
plot(function(x)
Thank you Peter. That is incredibly helpfyul, and much much smaller!
Best,
Collin.

The command line app is fine, although there are some potential security
issues or annoyances with a smooth work flow.
But it would be more flexible and powerful to do it directly in R.
And we don't need to know or program in C. The RCurl (https, getForm()
and postForm()) and XML packages
Wow.
Dont you get to name it on me or something (like the RPackageGoogleAjayDoc
?) Just kidding
This is fabulous and the reason this community is so innovative
Now if only someone can create a package for me to use R from Amazon EC2 and
be free of the damn RAM problem forever

For this kind of problem I'd go directly for the binomial
distribution. If the actual probability is 0, this is essentially
deterministic and you can look at
binom.test(0,99,p=.03, alt=less)
This means that you don't sample from the p=.03

written instructions for the computer on what to do in certain cases, but they
