Re: [R] Counting confidence intervals
The TeachingDemos package has %% and %=% functions that can be chained
simply, so you could do something like:
sum( 5:1 %=% 1:5 %=% 10:14 )
and other similar approaches.
The idea is that you can do comparisons as:
lower %% x %% upper
instead of
lower x x upper

For example, something that behaves more or less like
within - function(x, interval=NULL, closed=c(TRUE, TRUE),
lower=min(interval), upper=max(interval)) {
#interval must be a length 2 vector
#closed is taken in the order (lower, upper)

high.comp - if(closed[2]) = else

#Examples
within(1:5, c(2,4))
within(1:5, c(2,4), closed=c(FALSE, TRUE))
within(1:5, lower=5:1, upper=10:14)

Re: [R] Counting confidence intervals
You should look at findInterval. Used with as.numeric it could do what you
request although it has a much wider range of uses.

Re: [R] Counting confidence intervals
There _is_ a function ?within.
Drat! of course there is. I even use it, though not often.
Maybe your function can be
named 'between'
Good thought - thanks

Re: [R] Counting confidence intervals

Has anyone else ever wished there was a moderately general 'inside' or 'within'
function in R for this problem?
For example, something that behaves more or less like
within - function(x, interval=NULL, closed=c(TRUE, TRUE), lower=min(interval),
upper=max(interval)) {
#interval must be a length 2 vector
#closed is taken in the order (lower, upper)
#lower and upper may be vectors and will be recycled (by etc) if
not of length length(x)
low.comp - if(closed[1]) = else
high.comp - if(closed[2]) = else
do.call(low.comp, list(lower, x)) do.call(high.comp, list(upper, x))
}
#Examples
within(1:5, c(2,4))
within(1:5, c(2,4), closed=c(FALSE, TRUE))
within(1:5, lower=5:1, upper=10:14)
