HomeTypical R Error MessagesFixing R Error Message: longer object length is not a multiple of shorter object length

As annoying as error messeras might be, they tell you that something is going wrong. Often the message itself is not specifically useful, but there are situations wright here it tells you precisely what the problem is. The “longer object size is not a multiple of shorter object length” message is an instance one that tells you what the actual trouble is.

You are watching: R longer object length is not a multiple of shorter object length


When Does This Error Occur?

The “longer object length is not a multiple of shorter object length” R error occurs as soon as you are perdeveloping a role on vectors, and the vectors are not of the very same size. In such instances, the smaller vector restarts from the beginning.
> x = c(1,2,3,4,5,6,7)> y = c(1,2,3,4,5,6,7,8)> z = x + yWarning message:In x + y : longer object size is not a multiple of shorter object lengthIn this example “x” has actually salso numbers and also “y” has eight. Consequently “X” the formula pertains to the finish of “x” it hregarding start over. If the size of “y” is not a multiple of the size of “x” the process will not go back to the end of “x.”

What is causing this error?


*

The longer object length is not a multiple of shorter object length R warning message shows up when you area vectors of different lengths with a role. It occurs bereason the smaller sized vector does not end as soon as the larger one does.
In this first instance, “x” and “y” have the very same size and so no message is created.> x = c(1,2,3,4)> y = c(1,2,3,4,5,6,7,8)> z = x + yIn this instance, “x” has a length that is half the length of “y” and no message is developed. This is because in this instance “x” and also “y” end at the exact same time. What triggers this message is that the vectors cannot finish together. It is resulted in by a smaller one not being at its finish when the largest one reaches its finish.

How Do I Fix This Error?

Fixing this problem is rather easy! All you must do is make certain that the vectors are the very same length. When you just have two vectors, it is additionally easy to make sure the bigger length is a multiple of the smaller. This solution becomes more difficult when you usage even more than two vectors.> x = c(1,2,3,4,5,6,7)> y = c(1,2,3,4,5,6,7,8)> x = c(x, 0)> z = x + yIn this simple instance, all that is needed to fix this error is to include a zero to the finish of “x” but this strategy only functions when you recognize the lengths.

> x = c(1,2,3,4,5)> y = c(1,2,3,4,5,6,7,8)> for(i in ((length(x)+1):length(y)))+ x = c(x, 0)> z = x + yHere is a more basic way to settle this difficulty. It dynamically adds zeros to the end of “x” relying on the family member lengths of “x” and “y.” This strategy can be offered with any kind of adjustment you desire to use to make vectors the same size.We hope this tutorial on fixing the “much longer object length is not a multiple of shorter object length” R Error was useful, and encourage you to check out the rest of our site for all of your R programming needs!How To Make a Frequency Table in RHow To Make a Side-By-Side Boxplot in RR Error in eval(predvarsHow To Use colMeans in RUsual R Error Messages
