Actually, R is on par with C++ when it comes to _prefixed_ symbols lik
Greetings All!
With the Festive Season fast approaching, I bring you joy
with the news (which you will surely wish to celebrate)
that R cannot do arithmetic!
Usually, this is manifest in a trivial way when users report
puzzlement that, for instance,
sqrt(pi)^2 == pi
# [1] FALSE
which is the
Dear R-help
I am using Knitr and ggplot to draft an article and have now started to
improve on the layout and graphics. So far I have not been able to maintain
the same font size for labels in all my figures.
My goal is to be able to change the width of the figures while maintaining
the same font
Thanks very much Rich and Duncan. latticeExtra's resizePanels function
was a perfect solution.

I forgot about resizePanels but I sometimes have used the "old way" -- pre
latticeExtra to get exactly what I want.
I find it is easier to make small changes when trying to get a large number
of rows eg (5-7) etc onto a page especially in conjunction with modifying
the yaxis labels sensu

I have a vector like this (this vector is a colomn of a data set):
> 3 5 2 3 7 4 7 8 8 9 0 1 4
I want to separate elements of the vector by comma like this:
> 3,5,2,3,7,4,7,8,8,9,0,1,4
How can do this?
Thanks.

Hi,
Try:
vec1#vector
paste(vec1,collapse=",")

paste(xx,",", sep = "") but this coerces the vector to a character vector.

I wouldn't blame R for floating-point arithmetic and our personal
feeling of what 'zero' should be.

[1] TRUE
There was a similar post before, for example see:
http://r.789695.n4.n
Yes.
See also Feigenbaum's constant and chaos theory for the general context.

Also, the '+ 1' should be '+ 1L' to get the same answer as
seq_len(x)[-1].

Hi Daniel,
For some reason I cannot get your example to work. The problem is in the code
chunk but I have no idea what is happening. The code is running perfectly in R,
itself but LaTeX seems to be choking when it hits the first ggplot statement,
that is the one in <>=
The message I am gettin
Thanks for the comments, Bert and Mehmet! It is of course a serious
and interesting area to explore (and I'm aware of the chaos context;
I initially got into this areas year ago when I was exploring the
possibilities for chaos in fish population dynamics -- and they're
certainly there)!
But, befor

Hi Jo
Hi Daniel
I tried it in Sweave after modifying it for Sweave and a similar thing for
Latex but R crashed.
I think there is an embedded character/s before the first chunk and in the
first chunk.

R Users,
I have a data frame which I split using 2 factors using the split function:
split(datframe, list(f=factor1, f2=factor2));
I then used lapply to get some summary statistics grouped by factor1 and
factor2.
I now want to change the appearance of this output. I want to get a 2

I believe you missed

which does what you want I think (in the absence of a reproducible
example one cannot be sure).

Instead of RR function

you need to use equation for lognormal distribution. You can find it on internet

Another option is
