I am looking for an elegant way how I can test the equality of lengths of
multiple vectors.
For example, this is working fine:
> length(rnorm(4)) == length(rnorm(5))
[1] FALSE
However this is not:
> length(rnorm(4)) == length(rnorm(5)) == length(rnorm(6))
Error: unexpected '==' in "length(rnorm(4)) == length(rnorm(5)) =="
Ofcourse I can test it by taking pairwise vector i.e. (1,2), (1,3), (2,3)
and conclude all are of same length only if all 3 tests are passed. Is there
any better (R) way to doing that?
Thanks in advance
