Hi Jan,
In response to your ps. I think using rgdal is the best way to go. If
your data is for example in a GeoTIFF file, reading it is as simple as:
GRID = readGDAL(your_file.tif)
Saves you some hassel and a number of lines of code.

It depends what you mean by 'ignore'. Some functions have an na.rm
argument which throws out NAs before computing the statistic.
if the vector 'x' has NAs, then
x - x[!is.na(x)]
may be what you're looking for. This removes NAs from x and reassigns
the value to x.

Hi,

With the -2.7^8.6 you are doing -(2.7^8.6) it exists...
But, if you try (-2.7)^8.6 the R gives you NaN. When you define p=-2.7 and
q=8.6 and do p^q you are doing that (-2.7)^8.6.
If you write p=2.7 and q=8.6 and use the -p^q it will work!

does loess return the values that it produces- take that and then integrate
under the curve.

I think the previous answer (to use lm() ) is not necessarily the best
option.
Since what you want is the definite integral (area under the curve), you
can just use one of the existing definite integration tools (sorry, I
don't recall the names because I don't use them).
If you want to get

I have constructed a Trellis style xyplot.
lengthf - factor(length)
xyplot(SLI$velocity ~ SLI$width | SLI$lengthf, layout = c(2,7), xlab =
Width (cm), ylab = Velocity (m/s^2), col = black)
This produces a lovely little plot. However, the grouping factor(lengthf)
isn't in the right order. My

I would like to know the answer to this question now that I know what we are
getting at. integrate() looks like it is the right thing, but it has to use
a function- I would like to know how to just integrate the area under a
curve with just an input of x and y coordinates.

Here are some ways of rearranging panels:
library(lattice)
p - xyplot(Sepal.Length ~ Sepal.Width | Species, iris)
p
p[c(2, 1, 3)]
xyplot(Sepal.Length ~ Sepal.Width | Species, iris, as.table = TRUE)

I would like to integrate the area under a curve without any smoothing or
the like- just on the raw numbers. I looked at integrate() but it requires
a function which I assume means something like x+x^2+x^3
is there a built in function in R for this?
#let's say
x - seq(1:50)
y - seq(1:50)
Hoisted by own petard! How appropriate.
1. I hereby invoke the codicil.
2. Check the dictionary. An accepted pronunciation of inveigle is
inveegle.
Does this allow me to wriggle through the escape clause?

There is an integrate.xy in sfsmic. Limitations discussed there.

as.table =TRUE was exactly what I needed. Also thanks for the little aside.
