staRdom error - Fluorescence data processing

[Hercilio]

I am trying to clean up my fluorescence data using staRdom package (script below), but I keep getting this error: Error in eem_raman_normalisation2(eem_list, blank = "Blank_correction") : ***
*** First argument must be of class eemlist, second argument must be 'blank' for a blank correction, a number for correction with this number or a vector with a number for each sample

This script was working perfectly in my previous runs but now it is not working anymore and I don't know what is going on.

I really appreciate your help!

@Hercilio

eem_list <- eem_raman_normalisation2(eem_list, blank = "Blank_correction")

This is the line throwing the error. To see why,

• First, confirm that eem_list is of class emmlist
• Second, confirm that Blank_correction is a permissible argument

Details

Possible values for blank:

"blank": normalisation is done with a blank sample. Please refer to eem_raman_normalisation.

numeric: normalisation is done with one value for all samples.

data frame: normalisation is done with different values for different samples. Values are taken from a data.frame with sample names as rownames and one column containing the raman area values.

Blank_correction is given to eem_raman_normalisation2() as a character string, which is none of these.

Rob McCool, one of the team behind Netscape's web server, which eventually became Apache, had as a tagline It was working ten minutes ago, I swear. And it always drives me nuts when it happens to me between repo commits and I have no way to prove to myself that I haven't changed anything. Turns out that I almost always have changed something. When it happens right after ugrading a package, I jump through hoops trying to find how my code was victimized. Breaking changes, however, are much less common than needed to excuse my overlooking my own changes.
