as.numeric() is a built-in function in R that allows you to convert a character vector into a numeric vector. Therefore, it returns a numeric vector as an output.
- x = character vector
# creating a character vector char_data <- c('25', '50', '75', '100', '125') # converting the character vector to a numeric vector num_data <- as.numeric(char_data) char_data # confirming the vector has been converted is.numeric(num_data)
 "25" "50" "75" "100" "125"  TRUE
In the above example, we use is.numeric() to confirm if the vector has been converted to a numeric vector or not. The function returned TRUE, meaning the vector is numeric.
