[R] subset and "or" operator

[Erich Neuwirth]

subset(table, year %in% c(1995,1998,2000))-->table2

> Hello,
> I'm trying to subset a dataframe where I have many observation taken in different years.
> I would like to subset the dataframe (in this example called "table") to get a new dataframe containing only the 
> observation of year 1995, 1998 and 2000.
> I've tried to use subset and the or operator "|" like this:
> subset(table, year==1995|1998|2000)-->table2
> but the dataframe didn't subset and I get an object called table2 that is identical to table.
> I guess I'm doing something wrong!!
> 
> Thank in advance for any suggestions!
