r transform character variable to numeric variable

To transform a character variable to a numeric variable in R, you can use the as.numeric() function. Here's an example:

# Create a character variable
char_var <- c("1", "2", "3", "4", "5")

# Convert the character variable to numeric
num_var <- as.numeric(char_var)

# Print the numeric variable
print(num_var)

Output:

[1] 1 2 3 4 5

In this example, the character variable char_var is converted to a numeric variable num_var using as.numeric(). The resulting numeric variable contains the corresponding numeric values of the characters
