[R-sig-eco] Selecting levels from a list

[Jeffrey_Warren at fws.gov]

I'm trying to select multiple levels from a list of factors but have not
been able to.  Here is the list:

 lesc.ddl$p$time
 [1] 0.75  0.833 1     1.75  1.833 2     2.75  2.833 3     3.75  3.833 4
0.833 1     1.75  1.833 2     2.75  2.833 3     3.75  3.833 4     1
1.75
[26] 1.833 2     2.75  2.833 3     3.75  3.833 4     1.75  1.833 2     2.75
2.833 3     3.75  3.833 4     1.833 2     2.75  2.833 3     3.75  3.833 4
[51] 2     2.75  2.833 3     3.75  3.833 4     2.75  2.833 3     3.75
3.833 4     2.833 3     3.75  3.833 4     3     3.75  3.833 4     3.75
3.833 4
[76] 3.833 4     4
Levels: 0.75 0.833 1 1.75 1.833 2 2.75 2.833 3 3.75 3.833 4

And the code I've tried so far:

lesc.ddl$p$time==0.75 | 1.75 | 2.75  #returns all 'TRUE' values

lesc.ddl$p$time==c(0.75 | 1.75 | 2.75)  #returns all 'FALSE' values

Any help would be greatly appreciated.
