Create Categories Based On Integer & Numeric Range in R (2 Examples) | Convert Data to Factor Class

R code of this video:

num1 ＜- c(1, 4, 3, 7, 1, 4, 3, 3, 7) # Create numeric example data
num1 # Print numeric example data

class(num1) # Class of data

cat1 # Print categorical data

class(cat1) # Class of data

num2 ＜- rnorm(100) # Create numeric example data
head(num2) # Head of numeric example data

cat2 ＜- numeric() # Create empty data object
cat2[num2 ＜ - 1] ＜- 1 # Assign categories based on numeric range
cat2[num2 ＞= - 1 & num2 ＜ 0] ＜- 2
cat2[num2 ＞= 0 & num2 ＜ 1] ＜- 3
cat2[num2 ＞= 1] ＜- 4
head(cat2) # Head of categorical data

Great work Sir. I have a question. I have quarterly numerical score data. I am trying to group this data by letter grades such as A, B, C, D, E, F. Each letter grade will represent a range of value. From example 850+ is A, 740-850, 700-740 is B and so forth until F. Could you give some insight into how to do it. The purpose is to conduct a score migration analysis. Thank you
