mins = ave(D$Var,D$Site,FUN=function(x)min(x[x0],na.rm=TRUE))
D$Var = ifelse(is.na(D$Var) | D$Var == 0,mins,D$Var)
should do the required replacements.
Thanks Phil, that's great. I

Now is perfect!!
Thanks a lot

Hi R List,
I get this error using StatET R plugin in Eclipse.
You might have more luck asking the StatET user mailing list:

Dear all,
I wonder if there is a way to specify a model in differential equations for
nlme(). Or in other packages? Appreciate any comment. Thanks.

Hi Benoit,
You could turn the standard errors off with se = F. Then they'll be
removed from the legend as well.

Hi David all,
It is me again. When I try with a sample matrix (10x10) it appears to be
good.
But when I apply to a real 512x512 landscape, with values ranging from 1 to

For nlme, no. However, take a look at the CRAN Task View for pharmokinetics
and packages recommended there, especially nlmeODE .
You might also try R's search capabilities:
RSiteSearch(differential equations)
?RSiteSearch
of other non-R search engines

Hi,
Is there a way to build up a vector, item by item. In perl, we can
push an item onto an array. How can we can do this in R?
I have a loop that generates values as it goes. I want to end up with a
vector of all the loop results.
In perl it woud be:
for(item in list){
result -
How about ?append, but R is vectorized, so why not just
result_list - 2*item^2 , or for more complicated tasks, the
apply/sapply/lapply/mapply family of functions?
In general, the for loop construct can be avoided so you don't have to think
about messy indexing. What exactly are you trying to
The actually process is REALLY complicate, I just gave a simple example
for the list.
I have a lot of steps to process the data before I get a final
score. (nested loops, conditional statements, etc.)
Right now, I'm just printing the scores to the screen. I'd like to
accumulate them in

Hello,
I have searched for documentation on the function contourLines's algorithm
but cannot find a thing. I am about to submit a paper to a journal but
cannot yet do so because I need to provide some reference for this function.
Does anyone know what algorithm is used for this function?

Hello,
is there a way to write the result of a plot
to stdout? I mean even a binary thingy like
a png-file, written to stdout?!
I tried with the file-argument of png() and jpeg(),
but did not get working results.
Ciao,
