I don't quite follow what you are doing. Here is what Rui was suggesting using
your sample data
===================================================================
dat1 <- structure(list(name = structure(c(4L, 3L, 5L, 2L, 1L, 6L), .Label =
c("Andy",
"Bruce", "Ella", "John", "Luna", "Morgana"), class = "factor"),
address = structure(c(2L, 4L, 1L, 3L, 2L, 4L), .Label = c("Kiev street",
"london road", "main avenue", "Rome street"), class = "factor"),
phone = c(2123L, 2342L, 454L, 56775L, 287678L, 39876L)), .Names = c("name",
"address", "phone"), class = "data.frame", row.names = c(NA,
-6L))
dat2 <- structure(list(name = structure(c(4L, 4L, 3L, 3L, 3L, 5L, 5L,
2L, 2L, 2L, 2L, 1L, 6L, 6L, 6L), .Label = c("Andy", "Bruce",
"Ella", "John", "Luna", "Morgana"), class = "factor"), request =
structure(c(1L,
5L, 4L, 1L, 3L, 4L, 5L, 5L, 5L, 4L, 4L, 2L, 1L, 4L, 2L), .Label = c("book",
"cigarettes", "drink", "food", "paper"), class = "factor")), .Names = c("name",
"request"), class = "data.frame", row.names = c(NA, -15L))
mydata <- merge(dat1, dat2)
mydata
===================================================================
#If you need information about a variable in the merge try something like:
table(mydata$phone)
Is this of any help?
