Path Diagram
...d somewhere else, but I have been
searching for an answer all day and not been able to find one.
I am trying to plot a path diagram for a CFA I have run, I have installed

item7, item8, item9, item10, item11, item12', max.rank='SMP, AAAS',
file='documents')

Save using Update
Hi,
I want to update an existing row in table "items" where items.id == 10
I tried this:
item = Item.new
item.f1 = ...
item.f2 = ...
...
item.id = 10
item.save
I got an error
Duplicate entry ... for key 10 : INSERT INTO items ...
How do I make item.save to use UPDATE instead of INSERT?

Restructure some data
Suppose I have a data frame like "dat" below. For some context, this is the format that represents student's taking a computer adaptive test. first.item is the first item that student was administered and then score.1 is the student's response to that item and so forth.
item.pool <- paste("item", 1:10, sep = "")
set.seed(54321)
dat <- data.frame(id =
