Thanks, I did not realize it was deleting rows! I was afraid to try "pairwise.complete.obs" because it said something about resulting in a matrix which is not "positive semi-definite" (and googling that term just confused me more). But I ran the dataset through JMP and got the same answers so I t

Hi, I think in this case, when you use "na.or.complete", all the NA rows are removed for the full dataset. cor(swM[-1,1:2]) # FrtltyAgrclt  #Frtlty 1.000 0.3920289 #Agrclt 0.3920289 1.000 cor(swM[-1,])[1:2,1:2] #FrtltyAgrclt #Frtlty 1.000 0.3920289 #Agrclt 0
