identical(df[1,],df[2,]) is FALSE because of the row names. all( == ) is just a work-around that I attempted. Jorgen.
I would just wrap the elements in c(): identical( c(df[1,]), c(df[2,]) ) Peter Ehlers

[1] FALSE
all(df[1,]==df[2,])
[1] TRUE
all(df[3,]==df[4,])
[1] NA
I beg your pardon, whot does row names do with the above result? What do you expect as a result of all(df[3,]==df[4,]) Regards Petr
