Factoring out the GCF by breaking down your terms of a binomial
š In this video I will show you how to factor a binomial by working through four different examples. The first two examples we practice factoring out the GCF, and then move to factoring using a ...
Performance: as.factor > factor when input is integer A factor variable is the next of kin of an integer variable. ... This means that converting an integer to a factor is easier than converting a numeric / character to a factor. as.factor just takes care of this.

r - How to convert a factor to integer\numeric without loss of ...
The complete conversion of every character variable to factor usually happens when reading in data, e.g., with stringsAsFactors = TRUE, but this is useful when say, you've read data in with read_excel() from the readxl package and want to train a random forest model that doesn't accept character variables.
