Hi, Try ?unique() You haven't provided reproducible data or information about the package. So, this may or may not work.
dat1<- data.frame(idvar=c(rep(1,2),2,4),col2=c(7,7,8,9)) dat1 # idvar col2 #1 1 7 #2 1 7 #3 2 8 #4 4 9 unique(dat1) # idvar col2 #1 1 7 #3 2 8 #4 4 9 A.K. I got the following message when trying to use Google motion charts. Error in gvisCheckMotionChartData(data, my.options) : The data must have rows with unique combinations of idvar and timevar. Your data has 16264 rows, but idvar and timevar only define 16262 unique rows. > How do I find and remove the two duplicate rows?
