Hi
I am new to R programming and am using subset to
extract part of a data as follows
names(dataset) =
c("genome1","genome2","dist","score");
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.
Thanks
Lalitha
