Amor,
You have the possibility to use the duplicated() function.
A[!duplicated(A[,var]),]

Assunto: [R] SAS PROC SORT nodupkey
Hi,
I have the following data and I would like to delete douple names, it is almost
similar to SAS PROC SORT nodupkey! Is there any function in R does this?
x1 <- rnorm(11,5,1)
x2 <- runif(11,0,1)
nam <-paste("A", c(1:4,4,5:9,9), sep=".") mydata <- data.frame(x1,x2)
crownames(mydata) <- nam
Many thanks in advance,
Amor
