I am using a dataframe of my own (1737 obs of 2 variables, not too big) and I just want to plot it. It's an FTIR spectrum.
The line of code I'm using is pretty straightforward:
ggplot(data= P1, aes(x = Wavenumbers, y = Absorbance, group=1)) + geom_line()
Any idea what's going on? Why do those stains appear outside the axis?
