matrix2SpectraObject in ChemoSpec

by

I can’t seem to produce a Spectra object.
The file I am using look like this:

enter image description here

Column A: Wavelength
All other columns: Individual measurements

FTIR<- read.csv(file="FTIR_20190328_test.csv", header = T)
matrix <- matrix2SpectraObject (gr.crit =c("ID"),
                     gr.cols = c("auto"),
                     freq.unit = "Wavenumber",
                     int.unit = "Absorbance intensity",
                     descrip = "Treatment effects on necromass spectra",
                     in.file = "FTIR_20190328_test.csv",
                     out.file = "necro",)

I am getting error:

Error in matrix2SpectraObject(gr.crit = c("ID"), gr.cols = c("auto"),  : 
  could not find function "matrix2SpectraObject"

Can someone help me get this to work?
Thanks.

Described above.
I think it has something to do with the ID_ naming?

  • Your error says it cannot find the function matrix2SpectraObject, which suggests you have not yet called library(ChemoSpec) before running your code. Alternatively, try ChemoSpec::matrix2SpectraObject
