Change data type of one column in R

Question

I have a data frame of two columns, one with data type character and the other with numeric. Now I want to change the data type of one column from numeric to factorial. Is that possible?

Answer 1

Try this:

dataframeName$colName <- as.factor(datataframeName$colName)

Answer 2

You can change data types using as.* where * is the datatype to change to, the other way is using class().

class(df$var) = "Numeric".

The above method works only for a few combinations.
