I would like to loop a specific code through multiple files ending in .CDF in the same directory, but I am unsure of how to do that (new to R).
Can someone please help me with this-thank you.
This is the code I would like to loop:
> xr<-xcmsRaw("mh141210xg2_sccs_00101.CDF", profstep=0)
> write.mzdata(xr, file="mh141210xg2_sccs_00101.CDF")
And there are 675 of these .CDF files in the directory that I would like to apply the code to. Also, when I save the file in the second line of code, I would like it to have the same name as it previously had, so just re-write the old file.
Thanks so much for your time!!
