Using R to process spectroscopic data
Dear R-users,
I would like to process some spectroscopic data with R, and I was hoping
some people might have some example code on how to do this.
I would like to be able to do the following things:
* Detect outlier-spectra -> This can be done by using scoreplot from the
pls package
* Determine the range of the spectrum to be used -> For this, I should
be able to calculate the regression

click on graph and select data points?
Hi all,
I am doing some clustering and the clustered results are presented in a
"pairs" plot showing 4 clusters...
I made the data points belong to 4 different clusters displaying different
colors.
Now I want to select the best clustered class, how can I click on the data
point, and the program returns the index of that cluster(its class number,
or color number)?
Also, if I would

Matlab's lsqnonlin
Hi! I'm translating some code from Matlab to R and I found a problem.
I need to translate Matlab's function 'lsqnonlin'
(http://www-ccs.ucsd.edu/matlab/toolbox/optim/lsqnonlin.html) into R,
and at the beginning I thought it would be the same as R's 'optim'. But
then I looked at the definition of 'lsqnonlin' and I don't quite see how

eliminate t() and %*% using crossprod() and solve(A,b)
Hi
I have a square matrix Ainv of size N-by-N where N ~ 1000
I have a rectangular matrix H of size N by n where n ~ 4.
I have a vector d of length N.
I need X = solve(t(H) %*% Ainv %*% H) %*% t(H) %*% Ainv %*% d
and
H %*% X.
It is possible to rewrite X in the recommended crossprod way:
X <- solve(quad.form(Ainv, H), crossprod(crossprod(Ainv, H), d))
where quad.form() is a little

Smooth line in graph
Hi,
I?m trying to get smooth curves connecting points in a plot using
"spline" but I don?t get what I whant.
Eg.:
x<-1:5
y <- c(0.31, 0.45, 0.84, 0.43, 0.25)
plot(x,y)

Creates a valley between the first and second points, then peaks at 3rd,
and another valley between 4th and 5th. I?m trying to get a consistently
growing curve up to the 3rth point and then a

Compare linear regressios for significant differences of the slopes
Hi
I have (8 measures * 96 groups) = 768 datasets for which I did linear
regressions using lm().
Now I want to compare the slopes for each of the 8 measures in each of
the 96 groups. As I understand , I can not use

as the lm1 ... lm8 are based on different datasets.
I also read in previous discussions in this list, that I can see if the

transforming factor back to numbers
Hi
I generate a new dataframe by doing:

Now I want to plot it by using
coplot(npl.agg$x ~ npl.agg$year | npl.agg$sim, type="l")
but, as npl.agg$year is seen as a factor, the order of the points on the
x-axis (time axis) does not follow the numerical sorting 1...100, but
