Re: [R] find value between two other numbers?
Hi, I see no need to construct the vector, try this instead, belong = function(x=4, y=c(1,10)) x = y[2] x = y[1] see also ?findInterval HTH, baptiste On 13 August 2010 01:10, fishkbob fishk...@gmail.com wrote: So basically I want to do this - 4 %in% 1:10 should return true Would there be another way of doing this without having to do the 1:10 part?

Re: [R] find value between two other numbers?
Awesome, that works great, and it cuts my runtime down by a lot. thanks baptiste I totally forgot that I could just check to see if the number was inbetween via less than and greater than rather than having to construct the vector. findInterval also helps with another problem I was having somewhere else... -- View this message in context: http://r.789695.n4.nabble.com/find-value-between-two-other-numbers-tp2323513p2324409.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] find value between two other numbers?
Hi, Here is one way: is.there - function(mynumber, a, b) mynumber %in% a:b is.there(4, 1, 10) [1] TRUE is.there(459124, 103000, 983000) [1] TRUE is.there(4, 103000, 983000) [1] FALSE HTH, Jorge On Thu, Aug 12, 2010 at 7:10 PM, fishkbob wrote: So basically I want to do this - 4 %in% 1:10 should return true Would there be another way of doing this without having to do the 1:10 part?
