Maybe I'm just slow today but what are the columns? I had a look at the dataset
and it has no headers so reading it into R just supplies us with something like
: dput(head(sm))
sup <- structure(list(V1 = c(7L, 7L, 7L, 7L, 9L, 7L), V2 = c(6L, 8L,
8L, 9L, 9L, 6L), V3 = c(8L, 8L, 7L, 9L, 6L, 8L), V4 = c(8L, 8L,
10L, 8L, 7L, 7L), V5 = c(8L, 9L, 10L, 8L, 8L, 7L), V6 = c(30.25,
26.75, 28.75, 33.25, 32.25, 27.5), V7 = c(20.25, 33, 33, 32.75,
35.25, 25.5), V8 = c(29.75, 27.75, 25.75, 29, 23, 26.75), V9 = c(28.25,
30, 36.75, 26.25, 24.25, 30.75), V10 = c(24.5, 43, 41.25, 33.5,
34.75, 35.25)), .Names = c("V1", "V2", "V3", "V4", "V5", "V6",
"V7", "V8", "V9", "V10"), row.names = c(NA, 6L), class = "data.frame")
Presumably V1 is related to V6 somehow?
If so what is one expected to do with the data?
