Hi,
myvector<- c(3,2,7,4,1)
names(myvector)<-paste0("name",1:5)
names(myvector)[myvector>=3 & myvector<=5]
#[1] "name1" "name4"
#or
names(myvector)[myvector%in% 3:5]
#[1] "name1" "name4"
#or
names(myvector)[!is.na(match(myvector,3:5))]
#[1] "name1" "name4"

Hello all,
I am new to R but trying to learn.
I have a vector of names with visit frequencies (myvector) in the form
name1 name2 name3 name4 name5
3 2 7 4 1
I can select names of patients that have visited more often:
frequent.pats<-names(myvector) [myvector>5]
or those that have visited less often, but how could I get the names of those who visited, say between 3&5 times?
Thanks
steele
