I am hoping for some advice as to how to modify the following syntax, so
that instead of saving all records which refer to Farrah, I select all
instances that do not include Farrah, or the word Coolum.
test <- read.csv("c:\\newdat.csv", as.is=TRUE, header=T)
sure <- test[grep('Farrah', paste(test$V3.HD, test$V3.LP, test$V3.TD)),]
write.csv(sure,"c:/farrah4.csv")
Any assistance is appreciated,
regards
