Re: [R] Need to Write a Code that can find the molecular weight of various compounds

Thanks Paul, I was trying to get the function for getMass to input into another column into a data set using R code: FakeCompounds$Molecule <- with(FakeCompounds, getMolecule(Molecular.Formula)) showData(FakeCompounds, placement='-20+200', font=getRcmdr('logFont'), maxwidth=80, maxheight=3

[R] Need to Write a Code that can find the molecular weight of various compounds

Hi! Just started working at a lab and have only minimal experience with R. I was wondering if there was a way to write a code that would intake a data set of chemical compounds (ex: H2O, CH3) and be able to give an output column of the molecular weight? I tried some really basic coding to try to
