Here's one more way:
i[ findInterval(i, quantile(i, c(.25, .75))) == 1 ]

I'm trying to work out the simplest way to remove the upper and lower
quantiles, in this case upper and lower 25% from an array. I can do it in two
steps but when I try it in one, it fails. Is there something simple missing
from my syntax or are there other simple elegant way to accomplish this?
Thanks

i<-1:20
i2<- i[i<quantile(i,.75)]
i3<- i[i>quantile(i,.25)]
i4<- i[quantile(i,.25)< i> quantile(i,.75)]
Error: unexpected '>' in "i4<- i[quantile(i,.25)< i>"
