Hello,
It should be easu but I cannot figure out how to use apply function. I am
trying to replace negative values in an array with these values + 24.
Would appreciate help. Thanks,
Mark

shours <- apply(fhours, function(x){if (x < 0) x <- x+24})
Error in match.fun(FUN) : argument "FUN" is missing, with no default
