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

As annoying as error messages might be, they tell you that somepoint is going wrong. Often the message itself is not especially valuable, but there are cases wright here it tells you precisely what the trouble is. The “longer object size is not a multiple of shorter object length” message is an instance one that tells you what the actual difficulty is.

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


When Does This Error Occur?

The “much longer object length is not a multiple of shorter object length” R error occurs as soon as you are performing a role on vectors, and the vectors are not of the very same length. In such situations, 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 : much longer object size is not a multiple of shorter object lengthIn this example “x” has salso numbers and “y” has actually eight. Consequently “X” the formula involves the finish of “x” it has to start over. If the size of “y” is not a multiple of the size of “x” the process will not return to the finish of “x.”

What is causing this error?


*

The much longer object length is not a multiple of shorter object size R warning message shows up as soon as you place vectors of different lengths via a function. It occurs because the smaller sized vector does not finish once the bigger one does.
In this first instance, “x” and “y” have actually the same length and also so no message is produced.> x = c(1,2,3,4)> y = c(1,2,3,4,5,6,7,8)> z = x + yIn this instance, “x” has a size that is half the size of “y” and also no message is produced. This is because in this instance “x” and “y” end at the 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 end once the biggest one reaches its end.

How Do I Fix This Error?

Fixing this difficulty is rather easy! All you should perform is make certain that the vectors are the exact same size. When you only have two vectors, it is also easy to make certain the bigger length is a multiple of the smaller. This solution becomes more challenging as soon as you use 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 basic situation, all that is essential to settle this error is to add a zero to the end of “x” however this approach only functions once 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 an extra general means to fix this difficulty. It dynamically adds zeros to the end of “x” relying on the family member lengths of “x” and also “y.” This technique have the right to be used via any adjustment you desire to usage to make vectors the same length.We hope this tutorial on solving the “much longer object size is not a multiple of shorter object length” R Error was helpful, 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
