Hi
Structure is usefull for exchanging information and it is result of ?dput
function. I wonder if anybody would like to use it for **creating** data frames.
For creating data frames see functions like
?read.table,
?read.delim,
or other ?read.* functions.
Your questions are mainly adressed in
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
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)
Cheers

d <- data.frame(x=x, y=y, z=z)
sapply(d, class)
x y z
"factor" "numeric" "numeric"
d <- data.frame(x=x, y=y, z=z, stringsAsFactors=F)
sapply(d, class)
x y z
"character" "numeric" "numeric"
