Hi,
Not sure if the following is what you look for:
x - c(1:10, NA, 12:20)
sum(x[!is.na(x)])

Learn to use custom panel functions to give you the flexibility and
features you require.
In this case, you want something like:
xyplot(LRU~PAR|C3C4, groups = species,
panel= function(x,y,...){ ## custom panel function to add an
overall loess line
panel.superpose(x,y,...)
Buenas tardes,
cmo puedo con el R ajustar una distribucin exponencial truancada (en el intervalo [10,60]) a un vector de datos?
Muchas gracias.

Hello,
I have a dataset consisting of four variables: species (factor, five
levels), C3C4 (factor, two levels), and numeric variables PAR and LRU.
I wish to produce a scatter plot of PAR vs LRU where (1) each species
has a unique symbol and color (2) there is an overlaid loess line that
is
It is a long time since I have used oxmetrics/pcgive files. The data on the
file is in binary form and I do not know of any program that decodes it.
The easiest way to transform the dat would be to find a person who had
access to one of the oxmetrics oxmetrics programs who would read the file
and
Hi,
It appears that you want B to be rows 1 thru 4, 6 thru 9, 11 thru 14 and
16 thru 17 from A.
B - A[c(1:4, 6:9, 11:14, 16:17),]
E - A[16:19,]

Hi Kathryn,
Selecting the elements of matrix A as you describe is not too difficult:
select_A-function(A,B) {
thisA-A[A[,1] == B$p[1],]
newmat-matrix(c(rep(p[1],B$nq[1]),rep(thisA[,2],length.out=B$nq[1])),ncol=2)
for(i in 2:dim(B)[1]) {
thisA-A[A[,1] == B$p[i],]

Hola, ¿qué tal?
Creo que el ajuste (por máxima verosimilitud) de lambda es el inverso
de la media de tus datos. Tu densidad en el intervalo de interés es
como la de la exponencial (dividida por una constante de
normalización). El logaritmo de la verosimitud es, por lo tanto, como
el de la
Thanks, Bert, for the reply. This is very helpful. I have to admit
I've read the docs for the panel and panel.groups arguments before and
gotten myself pretty confused. Your small example is very helpful.
One more question for the list...
Bert's panel.loess col='darkblue' argument is being
1. The trellis.par.get$superpose.line list controls the loess line
appearance, I believe (check this!)
2. To control the overall loess curve in the panel, call it without
the ... arguments, e.g
panel.loess(x,y, col.line=darkblue)
You may have to modify argument lists appropriately if you want

Well, the OP already referred to segplot.
But, see, he shouldn't be doing this plot in the first place. Yes, I
know it's fairly standard in science, but it's a bad idea (as are many
others, like the infamous dynamite plot). If uncertainty intervals
are desired, they should be model based,
Thanks again, Bert, for taking the time to respond to my questions.
It's doing exactly what I want now. I'm fairly new with lattice plots
but they do seem like a big step forward. I'll look for Deepayan's
book; thanks for the tip.

This really annoyed since I thought this would be easy with some higher
order function.
Here is what I want:
I have a data frame with two columns, one is ID, another one is Name. I
want to get all rows whose name starts with some specific prefix. I thought
this should be a one-liner
Does the igraph function neighborhood() not do what you need?

Maybe this is due to the usage of rep() in ifelse():
f.rep - function(ans){ans - rep(ans,1);return(ans)}
f - function(ans){return(ans)}
f(a - 123) # no print here
f.rep(a - 123) # prints:
# [1] 123
