Thank you very much Peter.

Dear List members,
How can I re-arrange a data frame as detailed below.
old data frame
Item col1 col2 col3 col4
item1 12116 7
item2 108 5 4
item3 3 5 4 3
New data frame
item1 12 11
item1 6 7
item2 108
item2
Manuel,
You haven't specified the general problem, but for this particular
situation this is how you can do it:
x <- data.frame(array(1:12, c(3,4), list(paste("item", 1:3),
paste("col", 1:4
x <- data.frame(Item=rownames(x), x)
y <- data.frame(Item=x$Item[rep(1:3, each=2)],
matrix(as.matrix(x[
Here is an alternative approach that takes a few more steps and assumes the
original data frame is named d0:
# Split into two data frames
d1 <- d0[,c(1:3)]
d2 <- d0[,c(1,4,5)]
# Rename the columns in the second one so that the names match
names(d2) <- names(d1)
# Concatenate the two identically
Basil - you should do it for exactly the reason they state:
On page 138 of Zuur et al. (2009) they make the following statement
about a fitted model:
…there is a high correlation between the intercept and the slope for
arrival. This is because all arrival values are between 22 and 30 …
The interce
Sorry. It looked fine when I sent it. Below I've added back in the line feeds
that somehow disappeared.

You can check reshape or melt functions. They do exactly what you want.
