In this following example Id 4 is duplicated with Id 1.
Like this I want both Ids (Duplicated and Duplicated with). Can anyone help?
df<- data.frame(
"Publication" = c(1, 2, 3, 1, 4, 5, 2, 3),
"Reference" = c("a", "b", "c", "a", "d", "e", "b", "c"),
"Id"= c(1, 2, 3, 4, 5, 6, 7, 8)
)
key<- paste(df$Publication, df$Reference, sep="_")
df.key<- cbind(key, df)
Duplicated.ids<- df.key[duplicated(df.key$key), c("Id")]
Hi Sri krishna Devarayalu Balanagu,
Does this do it?
cat("Id Publication(s)\n")
for(pub in unique(df$Publication))
cat(pub,"-",df$Id[which(df$Publication==pub)],"\n")
