# What happens when you divide 2 vectors of unequal length in R?

This recipe explains what happens when you divide 2 vectors of unequal length in R

What happens when you divide 2 vectors of unequal length in R? When two vectors of unequal length are divided, the vector with shorter length will be recycled in such a way that it will match the length of the longer vector and then perform the division operation. This recycling of the shorter vector is known as the recycling rule. This recipe performs division of unequal vectors length.

Two vectors (for e.g: numeric) of unequal lengths are defined, here the length of vector b is a divide of the length of vector b.

```
a <- c(1:10)
b <- c(1:5)
print(length(a))
print(length(b))
print(a)
print(b)
```

The shorter vector b gets recycled and forms a vector of length (1:10) in order to match the length of vector a..

```
print(a/b)
```

"Output of the code is" [1] 1.000000 1.000000 1.000000 1.000000 1.000000 6.000000 3.500000 2.666667 [9] 2.250000 2.000000

Two vectors (for e.g numeric) of unequal lengths are defined, here the length of vector b is not a multiple of the length of vector b

```
x <- c(1:10)
y <- c(1:4)
print(length(x))
print(length(y))
print(x)
print(y)
```

A warning message is displayed when the length of the two vectors are not in proportion

```
print(x/y)
```

"Output of the code is" Warning message in x/y: “longer object length is not a multiple of shorter object length” [1] 1.000000 1.000000 1.000000 1.000000 5.000000 3.000000 2.333333 2.000000 [9] 9.000000 5.000000

In this data science project, you will predict borrowers chance of defaulting on credit loans by building a credit score prediction model.

In this human activity recognition project, we use multiclass classification machine learning techniques to analyse fitness dataset from a smartphone tracker.

Machine Learning Project in R- Predict the customer churn of telecom sector and find out the key drivers that lead to churn. Learn how the logistic regression model using R can be used to identify the customer churn in telecom dataset.

In this machine learning project, you will develop a machine learning model to accurately forecast inventory demand based on historical sales data.

The project will use rasa NLU for the Intent classifier, spacy for entity tagging, and mongo dB as the DB. The project will incorporate slot filling and context management and will be supporting the following intent and entities. Intents : product_info | ask_price|cancel_order Entities : product_name|location|order id The project will demonstrate how to generate data on the fly, annotate using framework and how to process those for different pieces of training as discussed above .

We all at some point in time wished to create our own language as a child! But what if certain words always cooccur with another in a corpus? Thus you can make your own model which will understand which word goes with which one, which words are often coming together etc. This all can be done by building a custom embeddings model which we create in this project

Deep Learning Project- Learn to apply deep learning paradigm to forecast univariate time series data.

In this machine learning project, you will use the video clip of an IPL match played between CSK and RCB to forecast key performance indicators like the number of appearances of a brand logo, the frames, and the shortest and longest area percentage in the video.

MLOps on GCP - Solved end-to-end MLOps Project to deploy a Mask RCNN Model for Image Segmentation as a Web Application using uWSGI Flask, Docker, and TensorFlow.

In this ML Project, you will use the Avocado dataset to build a machine learning model to predict the average price of avocado which is continuous in nature based on region and varieties of avocado.
