Re: [R] an apply question

Hi m p, You can use either apply(fhours, 2, function(x) ifelse(x < 0, x + 24, x) or shours <- fhours shours[shours < 0 ] <- shours[shours < 0 ] + 24 shours HTH, Jorge.- On Sat, Jan 19, 2013 at 4:17 PM, m p <> wrote: > Hello, > It should be easu but I cannot figure out how to use apply func
