Hi R-listers, I am trying to group my HTL data, this is a column of data of "Distances to the HTL" data = turtlehatch. I would like to create an Index of distances (0-5m, 6-10, 11-15, 16-20... up to 60). And then create a new file with this HTLIndex in a column. So far I have gotten this far: HTL.index <- function (values, weights=c(0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60)) { hope <-values * weights return (apply(hope, 1, sum)/apply(values, 1, sum)) } write.csv(turtlehatch, "HTLIndex", row.names=FALSE) ---- But I do not seem to be able to create a new column " in a new file. Please advise, Jean -- View this message in context: http://r.789695.n4.nabble.com/Grouping-distances-tp4632984.html Sent from the R help mailing list archive at Nabble.com.
