Most cases is that there is a missing quote somewhere in your data.
use a text editor and search for single and double quotes.

solution would be to avoid the internal use of deparse
when using match() or unique() on lists and to hash the
list element directly, but that is a fair bit of work.

Hi all,
I have a list x:
x=list(a=c('1','2'),b=c('2','3'),c=c('1','2'),d=c('2','3'))
I can get the unique elements with unique(), but how can I get the
number of duplicates for each unique elements?
unique(x)
