To convert factors to the numeric value in r, use the as.numeric() function.if the input is a vector, then use the factor() method to convert it into the factor and then use the as.numeric() method. In this way, we can use the factor column properly in our analysis otherwise r program will treat the factors as numerical values and the analysis output will be incorrect.
