The or() function is called any(). Similarly, the function you might
expect to be called and() is all().

hi, this may be trivial, but we can't seem to find anything adequate,
(although there is a work around with match() ). We are looking for something
along the lines of
plot(table1[table1$var2==or("a","b","c","d"),"var1"])
would be handy, with the potential or() function leading to what
plot(table1[table1$var2=="a" | table1$var2=="b" | table1$var2=="c" |
table1$var2=="d","var1"])
would do.
thanks for any hint
