Subject: [R] Logical "and"
I have the following very simple problem:
Say I have two vectors,
I would like to create a vector containing the elements in a which are not in
Obviously, this is possible by writing
a[a!=b & a!=b & a!=b]
But I would like a solution which is applicable to the situation where the
number of elements in b is unknown.
I have looked in the R manuals, the FAQ and the mailing lists, but have been
unable to find a solution.
Thank you for your replies,
