How to change the name of a data frame in R?

To change the name of a data frame, we can set the original name to the new name. Now both of the names can be used. Most of the times the purpose behind changing the name of the data frame is that, the original name does not seem to be a valid name based on the characteristics of the data. For example, if we have normally distributed columns in the data frame then we can name it as normal_distribution. This will help everyone to understand the data belongs to normal distribution.

set.seed(24)
x<−rnorm(20,1,0.25)
df1<−data.frame(x)
