Path Diagram
...answered 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
Rgraphviz and run the following:
pathDiagram(cfa, min.rank='item1, item2, item3, item4, item5, item6,
item7, item8, item9, item10, item11, item12', max.rank='SMP, AAAS',
file='documents')
I get the following message and output:

Why did TukeyHSD not work when I used it for post-hoc for 2way within-subjects anova?
..., I had 32 items each of which
generated 4 conditions. Participants saw each of the 32 items only once: 8
in Condition A, 8 in B, 8 in C, and 8 in D. The table below serves as an
example.
*Subject* *Factor1* *Factor2* *Condition* *ReadingTime* *Item* 1 A A A 238
Item1 1 A A A 369 Item5 1 A A A 494 Item9 *.* *.* *.* *.* *.* *.* *.* *.* *.
* *.* *.* *.* 1 B A C 294 Item22 1 B A C 694 Item26 *.* *.* *.* *.* *.* *.*
*.* *.* *.* *.* *.* *.* 8 A A A 334 Item3 8 A A A 366 Item7 *.* *.* *.* *.*

I did ANOVA by using the following

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 =
