patience.
I have 50000 spectra collected in field. Each spectra has two columns :
Wavelength (56) and the actual measurement.
Each measurement came in a different .txt file on disk (50000 files in

stupid regexp question
Hello,
I have a stupid regexp question. I have a large data frame of strings. I would
like to convert all occurences of :
"W.m^{-2}"
to
"W/m2"
I make the following test :
gsub(glob2rx("W.m^{-2}"), "W/m2", "W.m^{-2}")
but it does not seem to work. I don't know how to do it otherwise as I could
never learn how to deal with the special

log-transformed linear regression
Hello,
I have a basic question. Sorry if it is so evident....
I have the following data file :
http://ekumen.homelinux.net/mydata.txt
I need to model Y~X-1 (simple linear regression through the origin) with
these data :
load(file="mydata.txt")
X=k[,1]
Y=k[,2]
aa=lm(Y~X-1)
dev.new()
plot(X,Y,log="xy")
abline(aa,untf=T)
abline(b=0.0235, a=0,col="red",untf=T)

plotting with varying dot sizes
Dear all,
I am trying to plot on a spatial map the punctual measurements of the data
located in the file (https://opengeo.metu.edu.tr/test.csv). I'd like to have
the dots in some way proportional to the magnitudes of the measurements.
I have difficulties with the code given below: The dot sizes do not vary not
proportionally when varying the coefficient ("0.725"). It either plots
