[R] unique/subset problem

I am new to R programming and am using subset to
extract part of a data as follows

names(dataset) =
prunedrelatives <- subset(dataset, score < -5);

However when I use unique to find the number of unique
genomes now present in prunedrelatives I get results
identical to calling unique(dataset$genome1) although
subset has eliminated many genomes and records.

I would greatly appreciate your input about using
"unique" correctly  in this regard.
