Convert Numeric to Character Column in R DataFrame

To convert a numeric column to a character column in R DataFrame:

df$column_name <- as.character(df$column_name)

Example of Converting Numeric to Character Column in R DataFrame

Here is an example of converting the numeric ‘Age‘ column to a character column in R DataFrame:

# Create a sample DataFrame
df <- data.frame(
                Name = c("Jon", "Bill", "Maria"),
                Age = c(25, 32, 28)
                )

# Display the original DataFrame
print("Original DataFrame:")
print(df)

# Print the data types before conversion
print("Data Types Before Conversion:")
str(df)

# Convert the Age column to character
df$Age <- as.character(df$Age)

# Print the data types after conversion
print("Data Types After Conversion:")
str(df)

Note that the str(df) was added to print the data types of the columns in the DataFrame before and after the conversion.

Here are the data types before and after the conversion of the ‘Age‘ column from numeric to character:

[1] "Original DataFrame:"

   Name Age
1   Jon  25
2  Bill  32
3 Maria  28

[1] "Data Types Before Conversion:"
'data.frame':   3 obs. of  2 variables:
 $ Name: chr  "Jon" "Bill" "Maria"
 $ Age : num  25 32 28


[1] "Data Types After Conversion:"
'data.frame':   3 obs. of  2 variables:
 $ Name: chr  "Jon" "Bill" "Maria"
 $ Age : chr  "25" "32" "28"

As seen in the original DataFrame, the ‘Age‘ column had a numeric data type (highlighted in yellow).

However, after the conversion, the ‘Age‘ column’s data type changed to character (highlighted in green).
