Hello,
I tried the approx() and it worked. Now, I have a list named "interpol"
resulting from the interpolation. I would like to append the values in
interpol$y in the position specified by interpol$x in a existing vector
"spect1". I tried with append() and the following code:
spect1 <- c(1:10909)
for(i in 1:length(interpol$x)){
append(spect1,interpol$y[i],interpol$x[i])
}
but it didn't work. Any idea?
Best,
Dani
