Sort answer is that unique() gives the unique elements rather than something
you should subset by, like a set of logical indices or row numbers.
Note that in general unique(x) == x[!duplicated(x)] I'd imagine there are cases
where this
I believe you want the duplicated() function.

HI,
this is my problem I want to subset this file df, using only unique
df$exon printing the line once even if df$exon appear several times:
unique(df$exon) will show me the unique exons
If I try to print only the unique exon lines
with df[unique(df$exon),] -this doesn't print only the unique
