sem is not "taking" the model
A strange problem with sem:
I downloaded the sem library and then, I specified my simple measurement model (below). I highlighted it and ran it. It ran, but it did NOT tell me "22 lines read". And nothing works after that - it looks like it runs, but it does not produce anything...
Did I make a mistake somewhere in the model? (notice, TIME has only 1 indicator - t1, and I fixed t1's

Despite a long search on the archives, I couldn't find how to do this.
Thanks in advance for what is likely a simple issue.
I have a data set where the first column is name (i.e., 'Joe Smith',
'Jane Doe', etc). The following columns are data associated with that
person. I have many people with multiple rows. What I want is to get a

how to calculate another vector based on the data from a combination of two factors
Hi,
I have a data set similar to the following
State Gender Quantity
TX Male 1
NY Female 2
TX Male 3
NY Female 4
I need to calculate cumulative sum of the quantity by State and Gender. The
expected output is
State Gender Quantity CumQuantity
TX Male 1 1
TX Male 3 4
NY Female 2 2
NY Female 4 6
I highly appreciate if someone can give me some hints on solving that in R.

Confidence interval bars on Lattice barchart with groups
I am trying to add confidence (error) bars to lattice barcharts (and

Creating subsets of a matrix
Hello,
Say I have 2 columns, bmi and gender, the first being all the values and the
second being male or female. How would I subset this into males only and
females only? I have searched these fora and read endlessly about select[]
and split() functions but to no avail. Also the table is not ordered.
bmi gender -> bmi gender + bmi gender

Grouped AND stacked bar charts possible in R?
Good day all,
My statisticians want an R procedure that will produce grouped stacked
barplots. Barplot will
stack or group, but not both. The ftable function can produce a table
of the exact form they want, but the barplot doesn't show all the
divisions we want.
For an example, here's the sample from the help file for "ftable:"
data(Titanic)
ftable(Titanic, row.vars = 1:3)

I found a website which reccomended using two commands:

to convert to numbers, and:

duplicated factor labels.
To extwnd on Martin 's explanation :
In factor(), levels are the unique input values and labels the unique
output values. So the function levels() actually displays the labels.

The program should act on the data, if the textfile is source()'ed

Creating a vector of categories
Hi,
I have a column in a data frame looking something like:

What I want to do is to order these in to categories, for instance one
category where count>=0 & count<10 and so on..
I want my data to turn out looking something like:

I need to create new variables based on two numeric variables and one dichotomize conditional category variables.
I might have factored the gender.
I'm not sure it would in any way be quicker. But might be to some extent
easier to develop variations of. And is sort of what factors should be
doing...
# make dummy data
gender <- c("Male", "Female", "Male", "Female")
WC <- c(70,60,75,65)
TG <- c(0.9, 1.1, 1.2, 1.0)
myDf <- data.frame( gender, WC, TG )
