Hello!
I have used read.csv to read in a data frame, and there are a few variables in
it, however, when I tried
is.list(data$V1)
>FALSE
In fact, I have tried, they are not vectors either.
I'm wondering:
1. What objects are these "lists" of data?
2. How could I find out about the type/inheritence of an object in general?
3. The reason I want it to be a list or vector, is that I want to fill in some
blank values, i can't seem to do things like:
data$V1[1] = 3
Is it because these variables are pointers? Is there a better way to do this?
Sorry to cram so many questions in one email!
Karen
