Hello there ... Using package Peaks to run the function SNIP on a csv file with 19 spectrum.
While trying to run: ### doing SNIP for every spectra require(Peaks) for (i in 1:NROW(Q)) { Q.t[i,]<-Q[i,]-SpectrumBackground(as.numeric(as.vector(Q[i,]))) print(i) } Got the following error: Error in .Call("R_SpectrumBackground", as.vector(y), as.integer(iterations), : "R_SpectrumBackground" not available for .Call() for package "Peaks" Any suggestions on how to correct this ? Thanks for the help, Edmir Fiber&Polymer Science, NCSU [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
