```Hi Burnette,

Try:
indx <- grep("\\bMW\\b|\\bOT\\b|\\bposter\\b|\\brecords\\b", rownames(res3))
indx1 <- grep("Grand Total",rownames(res3))

res3R
<-
as.data.frame(matrix(NA,ncol=ncol(res3),nrow=nrow(res3),dimnames=
list(rownames(res3),c("rate of Count of Case ID", "rate of Sum of
BW_Due", "rate of Sum of BW_ATP", "rate of Sum of EEs_Rep"))))
res3R[c(indx,indx1),] <- t(t(res3[c(indx,indx1),])/unlist(res3[indx1,]))
indx2 <- as.vector(table(gsub("\\_.*","",rownames(res3[-c(indx,indx1),]))))
#or
#indx2 <- res3[indx,1]

res3R[-c(indx,indx1),] <- res3[-c(indx,indx1),]/unlist(res3[rep(indx,indx2),])
res4 <- cbind(res3,res3R)[,rep(seq(1,8,by=4),4) + rep(seq(0,3),each=2)]

#       Count of Case ID rate of Count of Case ID Sum of BW_Due
#MW                    2                      0.4        168.11
#MW_tip                1                      0.5         55.76
#       rate of Sum of BW_Due Sum of BW_ATP rate of Sum of BW_ATP Sum of EEs_Rep
#MW                 0.7202348        155.86             0.7953664             29
#MW_tip             0.3316876         55.76             0.3577570              9
#       rate of Sum of EEs_Rep
#MW                  0.5370370
#MW_tip              0.3103448

A.K., I’m struggling with adding columns that calculate rate in the dataset you helped me with earlier:

Is this something I should resubmit to Rhelp as a new question?  Thanks!

FLSAdata <- data.frame(CaseID = c(1881, 1882, 1883, 1884, 1885),
