#Let's say I have the following data set:
dat3 = data.frame(A_CaseID = c(1881, 1882, 1883, 1884, 1885),
B_MW_EEsDue1 = c(2, 2, 1, 4, 6),
C_MW_EEsDue2 = c(5, 5, 4, 1, 6),
D_MW_EEsDueTotal = c(7, 9, 5, 6, 112))
dat3
# A_CaseID B_MW_EEsDue1 C_MW_EEsDue2 D_MW_EEsDueTotal
# 1 1881 2 5 7
# 2 1882 2 5 9
# 3 1883 1 4 5
# 4 1884 4 1 6
# 5 1885 6 6 112
# I want to:
#CREATE A NEW 1-COLUMN MATRIX (of unknown #rows) LISTING ONLY "A"'s WHERE "D
!= B + C"
#THIS COLUMN CAN BE LABELED "MW_EEsDue_ERRORS", and output for this example
should be:
# MW_EEsDue_ERRORS
# 1 1882
# 2 1884
# 3 1885
#What is the best way to do this? Thanks for your time. BNC
