The following line of code seems fairly straight forward, yet it is kicking back an error message: for (i in 1:length(mean.natveg.frac)){month.observed[i]=as.numeric(names(mean.natveg.frac[i]))%%12}Error message: Error in month.observed[i] = as numeric(names(mean.natveg.frac[i]))%%12 : object 'month.observed' not found Seems like its not found because I'm trying to define it. Also length(mean.natveg.frac) = 103
You can't index the object before it is defined. You can assign to non-existent elements of an object, but it is very inefficient. So the best fix is to put the line
month.observed <- numeric(length(mean.natveg.frac)) before the for loop.
