Dear all,

I want to extract rows from a data frame shown here as "test". For example:
rows with with sorting
 PKB123  PKB22  PKB23  PKB32  CTV19  CTV20  PKB11  PKB11

> dput(test)
structure(list(Name. = structure(c(1L, 2L, 3L, 4L, 5L, 6L, 7L,
8L, 9L, 10L, 11L, 12L, 12L, 13L, 14L, 15L, 16L, 17L, 18L, 19L,
19L), .Label = c("CTV10", "CTV11", "CTV12", "CTV13", "CTV14",
"CTV15", "CTV16", "CTV17", "CTV18", "CTV19", "CTV20", "PKB11",

), class = "factor"), Score = c(1, 3, 4, 5, 2, 3, 4, 5, 6, 2,
3, 4, 5, 5, 4, 3, 2, 5, 6, 6, 2), performance = c(0.1885092462,
