complex(?) reshaping question
Hello,
I have a problem with data reshaping. Here's my data
DF <-
structure(list(idvar1 = structure(c(1L, 1L, 1L, 1L, 1L, 1L, 1L,
1L, 2L, 2L, 2L, 2L, 2L, 2L), .Label = c("patient1", "patient2"
), class = "factor"), idvar2 = structure(c(1L, 1L, 1L, 1L, 1L,
1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 2L), .Label = c("dob", "hog"), class =
"factor"),
eka1 = structure(c(NA, NA, NA, NA, NA, NA, NA, NA, 2L, 1L,
NA, NA, NA, NA), .Label = c("as", "df"), class = "factor"...
