I have this type of format: structure(list(day = 19, C1 = structure(1L, .Label = c("", "C1" ), class = "factor"), C2 = structure(2L, .Label = c("", "C2"), class = "factor"), C3 = structure(1L, .Label = c("", "C3"), class = "factor"), Q1 = structure(2L, .Label = c("", "Q1"), class = "factor"), Q2 = structure(2L, .Label = c("", "Q2"), class = "factor"), Q3 = structure(1L, .Label = c("", "Q3"), class = "factor")), .Names = c("day", "C1", "C2", "C3", "Q1", "Q2", "Q3"), row.names = "8", class = "data.frame") >
and want something like this: 19 -C2 _Q1_Q2 any ideas? obviously I could use paste() and get this. Keep in mind I have many of these and the presence of "C1", "C2", ... etc will vary.
