OrgMassSpecR peak area issue
Hello!
I am having an issue with the OrgMassSpecR package. I run my HPLC using a
DAD detector. My raw data is exported form chemstation as a csv file. I
then upload the csv into Rstudio no problem. Using the DrawChromatogram
function, I get a nice chromatogram, and my retention time, peak area, and
apex intensity values are given as well.
The problem comes with the peak area value given. The peak area is much
smaller than a value that would make sense. My peak area value is actually
less than my apex intensity value....

I have the absorbance values form HPLC Chromatogram. I need to find the
peaks in datapoints and area under each peak.
I am not sure how how to find the peaks, I tried couple of libraries and
peak function but they return me a list of values which when computed from
area turns out to be huge nnumbers. In the
