nls: Fitting two models at once?
...both spectra are connected in some way: the stoichiometry of coefficients
"cytf.v"/"cytb.v" is 1/2.
{{In the SigmaPlot workflow one has to copy the two spectra into one column
beneath each other and the two spectra are somehow treated as one curve -
like in http://home.arcor.de/ballaschk/cytbf-help/sigmaplot%20formula.png}}
Can anybody help? :(
I tried to condense everything to the "minimum" R script below to give an
impression of what I'm talking about.

help: selection of data
Hi,
I'm not very experienced with R and struggle with data selection from a long
matrix with two columns.
I want to cut out the data between x > 0 and min(y).
> x <- c(-10, -5, 0, 5, 10, 15, 20)
> y <- c(10, 10, 10, -5, -6, -7, 10)
> data <- as.matrix( cbind(x, y) )
> data
x y
[1,] -10 10
[2,] -5 10
[3,] 0 10 _
[4,] 5 -5 |-- data interval
[5,] 10 -6
