equating approximate values

Change which to which.min, but then you won't easily be able to get the corresponding x,y indices. Look at the arrayInd() function to translate the result to a particular x,y.
The arrayInd help page is shared by the which help and which has an arr.ind=TRUE option that let's you encapsulate both steps: which( abs(outer(x, y, "-")) == min(abs(outer(x, y, "-"))), arr.ind=TRUE)

this is exactly what i wanted. How to i select only the minimum value from this?. thank you My apologies: you need an abs() call as well: which(abs(outer(x, y, "-")) < threshold, arr.ind = TRUE) Michael -- View this message in context: http://r.789695.n4.nabble.com/equating-approximate-values-tp4157551p4158691.html Sent from the R help mailing list archive at Nabble.com.
