You seem to be trying to learn R ... sideways... or backwards, perhaps.
Have you read An Introduction to R[1], included with every copy of the
software? In particular, there are sections on data frames [2] (which
should be read in the context of the discussion on lists, as it
is presented. The
Hello everyone,
Is there any way to create a data.frame from scratch? other than, say, this?
> structure(list(Fruit = structure(c(1L, 2L, 5L, 4L, 3L), .Label =
c("apple",
"banana", "kiwi", "orange", "pear"), class = "factor"), Color =
structure(c(3L,
4L, 1L, 2L, 1L), .Label = c("green", "orange",
Just make d <- data.frame(x,y,z).
cbind forces x,y and z to be of the same type.

Hi Joe,
cbind coerces the data to be the same type. Much nicer is:
d <- data.frame(x=x, y=y, z=z)

OK...newbie question here.
Either I'm reading the docs wrong, or I'm totally confused.
Given the following:
x<-c("aaa","bbb","ccc")
y<-rep(0,3)
z<-rep(0,3)
is.character(x)
[1] TRUE
is.numeric(y)
[1] TRUE
Now...I want to create a data frame, but keep the data types.
In reading the docs, I assum
