comparing columns in a dataframe
...ow numbers where there
is difference in the variables (either pairwise or between 3 variables).
x <- read.csv("c://rec_compare.csv",header=T, as.is=TRUE)
u <- union(x$rm1, x$redc1)
write.csv(u,"c:/union_test.csv")
i <- intersect(x$rm1, x$redc1)
write.csv(i,"c:/intersect_test.csv")
sd <- setdiff(x$rm1, x$redc1)
write.csv(sd,"c:/setdiff_test.csv")
Any suggestions are appreciated.
