Sadly not. The residual scale in a robust model is only partly indicative of
goodness of fit; robust models intentionally downweight outliers. Much of the

Hello,
I am working on a simple ODE problem with the deSolve package, and I was

does integration.
Here is my program:

so I'm relatively new in R, but normally i don't have big problems by using

I would like to do multiple actions on a subset of my data. Therefore, I want
to create a for loop on the variable "Date" (actually a double for loop on yet
another variable, but let's omit that for a moment).

I'm now dealing with some NetCDF files for my scientific work and I'm
reading it and manipulating it with R.
So far I would like to ask some questions:
1. I have a NetCDF file for time-series data (*daily* time step) in a
domain (with longitudes and latitudes) with two varia
Hi,
What about using functions like aggregate()?
Something like:
aggregate(Weight~datums, data=dataset1, FUN=mean)
If you need to do more things, you can create your own function for 'FUN'

Hi Thanh:
You are confounding several issues here, and are providing only incomplete
information about your data. The confounded issues are:
1. How to write a netcdf with a given coordinate system.
2. How to calculate a monthly average or monthly subsample from a larger
sample.
I would gu
We are not going to be able to help much without the data. You say it is "more
or less" the same as the example data so maybe it is "less" similar than you
think.
Another possibility is that you keep using fix() for some reason that you have
not explained. That function calls edit() which can

Assuming datums is a vector of the unique dates in Date... perhaps
datums <- sort(unique(dataset1$Date))
I usually set it up like this
for (i in 1:length(datums) ) {
crnt.date <- datums[i]
tmpdat <- subset(dataset1, Date==crnt.date)
cat(i, format(crnt.date), 'dim(tmpdat)',dim(tmpdat),'\n

in a list.
Some of the dataframes won't have any rows that have this condition

Hi Gabriel,
As far as I could recall, there isn't an R package that has explicitly
implemented "vincentization". You definitively can find some code
segments/functions that have implemented "vincentize" on the web. But you
should verify if they do exactly wha

On Wed,
I have one more suggestion:
Consult a local statistician. Psychology, neuroscience (and a host of
other professions that I have encountered) are full of bad statistical
practice and reinvention of wheels. "Vincentizing" sounds suspiciously
like such an example. A statistician could help you sort it
