Arun, thanks for clearing that up. I was making assumptions about R that I
shouldnât have when it comes to column(variable) assignments. Hope everyone
has a good Monday. BNC

AK, I decided to convert your âwithâ statement back to index-by-number, and
I did look up the ?with help info, but Iâm confused about my replacement code
below. I got the wrong answer (R didnât apply the function to my column 1
variable âA_CaseIDâ). What am I doing wrong? Do I nee

You understood me perfectly, and I agree is it easier to index using numbers
than names. I'm just afraid if my dataset gets too big I'll mess up
Oh, also thanks for the speed comparisons. Missed that in my first
read-through. Very interesting and informative. BNC

Hi,
You could try:
mat1<-matrix(dat3[rowSums(dat3[,2:3])!=dat3[,4],1],ncol=1,dimnames=list(NULL,"MW_EEsDue_ERRORS"))
mat1
# MW_EEsDue_ERRORS
#[1,] 1882
#[2,] 1884
#[3,] 1885
