When this error may occur

Consider that we have two vectors vect1 and vect2. Both contain 5 and 4 elements respectively.

Example:

Now let’s try to subtract and print corresponding values.

Output:

Interpretation of output:

The output shows the difference of the corresponding values in each vector. We received the warning message because the 2 vectors are of unequal length. Note that the R compiler uses the difference between the last element of vect1 and also the first element of vect2. Hence, we will say that the values are repeated in a very circular form.

When we are unaware of the particular lengths of the vectors. Then, it’s advisable to test the lengths of the vectors beforehand. In R we’ve got the length() function that’s accustomed to determine the number of elements present in vectors.

In this article, we will be looking at the approach to fix the “longer object length is not a multiple of shorter object length” error in the R programming language.

This is a warning message produced by the R compiler. The complete form of this warning message is given below:

Warning message:
In vect1 + vect2 : 
longer object length is not a multiple of shorter object length

Reason: Such an error might occur in R when we try to do some operations on the vectors having unequal lengths.
