Summarise Data in R – How to know datatypes in R

In R, it is important to know the data types of variables in a dataset, as different data types require different types of analysis and processing. The most common data types in R are numeric, character, and factor.

To check the data types of variables in a dataset, you can use the str() function in R. This function takes a data frame or a vector as an argument and returns the structure of the dataset, including the names of the variables and their data types.

For example, if you have a dataset called “data”, you can check the data types of the variables in the dataset by using the command str(data)

You can also use the class() function in R to check the data type of a specific variable. This function takes a variable as an argument and returns its data type. For example, if you have a variable called “var1” in your dataset, you can check its data type by using the command class(var1)
