[Newbie] Row-Iterator for data.frame??
...ble$WN4000 / 1.34 .
but for some reasons i have to iterate through the spectra, especially when
i want to differentiate a curve, because then i first have to build a interpolation
polynom from the given x-points and y-values of a specific case.
i wrote a function getCase <- function( dataFrame, caseNo) with return-value
of type data.frame and holding the case "caseNo" of the dataFrame.
now, this results in absolutely bad performance.
my question:
what is the most convenient and fastest way to access a single row of a
data.frame? if possible, i'd like something i could use like...

accomplish the following in the easiest way possible. I would like to have a
~3 prompt VM system, that would ask for some numbers from a caller (case
number, id and another id). It would then take their DTMF presses and format
an email to a predetermined address (i.e. the email always goes to the same
place). I don't really

Calculate Closest 5 Cases?
I've only begun investigating R as a substitute for SPSS.
I have a need to identify for each CASE the closest (or most similar) 5
other CASES (not including itself as it is automatically the closest). I
have a fairly large matrix (50000 cases by 50 vars). In SPSS, I can use Correlate > Distances to generate a matrix of similarity, but only on a small sample. The entire matrix can not
