R dataframe column to character array

I am newbee to R.

Trying to play with this language a bit. All I am trying is

1) I have a dataframe "df", which has one column "desc" which is String 2) I did a load csv to create the dataframe

Issue:

1) when I am doing w <- df$desc
it is returning a object but I am unable to figure the object. I tried is.vector, is.charaecter(w) nothing returns "true". I was going thru a book and it mentioned it should be a vector.

2) I have to create a character array to do further processing can anyone please help me how to do the processing or conversion

Thanks, Amit

If you want to know the class of an object, use this:

class(w)

or, if you want to know the classes of all the columns in a data.frame (called "X" in this example), try this:

sapply(X, class)
