HI Team, I am currently working on problem and stumped on "for" loop.
Data: structure(list(Coutry = structure(c(3L, 3L, 3L, 3L, 2L, 2L, 1L, 1L), .Label = c("J", "M", "U"), class = "factor"), State = structure(c(1L, 1L, 4L, 2L, 5L, 5L, 3L, 6L), .Label = c("A", "C", "K", "O", "S", "T"), class = "factor"), City = structure(c(1L, 8L, 7L, 2L, 3L, 6L, 5L, 4L), .Label = c("BEN", "HRD", "JKL", "KK", "KL", "KMM", "OKC", "TYU"), class = "factor"), Char1 = structure(c(1L, 2L, 1L, 3L, 4L, 2L, 3L, 5L), .Label = c("A", "B", "C", "D", "M"), class = "factor"), Char2 = structure(c(1L, 2L, 1L, 2L, 3L, 4L, 4L, 2L), .Label = c("ABCD", "EFGH", "FGHJ", "GGGG"), class = "factor"), Char3 = structure(c(1L, 1L, 2L, 3L, 1L, 1L, 2L, 3L), .Label = c("ASDFG", "DDDDD", "EEEEEE"), class = "factor")), .Names = c("Coutry", "State", "City", "Char1", "Char2", "Char3"), row.names = c(NA, -8L), class = "data.frame") Question: I am trying to create a pivot table which will count the occurrences of Char1 : Char4 from the columns Coutry, State, City. I am not sure to use all the four columns and get something like structure(list(Group.1 = structure(1:4, .Label = c("ABCD", "EFGH", "FGHJ", "GGGG"), class = "factor"), x = c(2L, 3L, 1L, 2L)), .Names = c("Group.1", "x"), row.names = c(NA, -4L), class = "data.frame") Code which I tried to use with not best results: aggregate(State, list(Char2), FUN="count") Best Regards, Bhupendrasinh Thakre [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
