Hi. You can try this:
df[type%in%type_list, ]
You can also use sqldf package and subset data frames usign sql statements:
library(sqldf)
df <- data.frame(x1=1:10, type=10:1)
type_list <- data.frame(index=seq(1,10,by=2))
sqldf("select df.*
from df
where df.type in (select * from ty

that the type belongs to a "type_list";
using sql, I want
SELECT name, type FROM df
WHERE type in type_list;
Now in R I have to write a loop like
mysubset<- df [ df$type == type_list[1], ]
for (type1 in type_list[

Thank you.
I put table(factor(x.sub$RES_ID)) and works.

Great, this worked for me, exactly how I needed it.
