Drupal has a graphiviz filter, with what seems like pretty straight-forward installation:

http://drupal.org/project/graphviz_filter

Would be great to have that installed here, and enabled as a filter in the wiki, forums, and docs: Very helpful if people can include diagrams in posts.

hi
open trunk/demo/DefinitionMeans_MatrixRaw.R

is broken
error = Running Definition Means -- Matrix Specification
Error: The thresholds matrix/algebra 'x' for model 'Definition Means -- Matrix Specification' does not exist.

be nice if that error was more helpful too: I can't figure it out: There are no thresholds, there is no algebra called "x", x is not used in any algebra, it's the name of a data column

In the example: http://openmx.psyc.virginia.edu/docs/OpenMx/latest/TwoModelStylesTwoDataStyles.html#model-specification the diagram has a means triangle, but the model with the means path is introduced later in the example. The page states "Below is the path diagram and the complete script:". There should be two figures, the first one should not have the means triangle and the second one should have the triangle.

the code below generates and estimates the variance and mean of one variable, and should make a diagram like this:
http://openmx.psyc.virginia.edu/docs/OpenMx/latest/TwoModelStylesTwoDataStyles.html#model-specification

instead it generates an error

testData = as.matrix(rnorm (1000, 0, 1))
selVars c("X")
dimnames(testData) <- list(NULL, selVars)
univSatModel1 <- mxModel("univSat1", manifestVars= selVars,
mxPath(from="X", arrows=2, free=T, values=1, lbound=.01, labels="var X"),
mxData(observed=testData, type="raw"),
type="RAM"
)
fit = mxRun(univSatModel1)

here:

http://openmx.psyc.virginia.edu/docs/OpenMx/latest/BeginnersGuide.html#matrix-model-specification

the model lacks the commas separating model elements, and a closing bracket for the model statement

UPDATE: this has also happened here

http://openmx.psyc.virginia.edu/docs/OpenMx/latest/BeginnersGuide.html#alternative-formulation

The problem is in part that the closing bracket has migrated to the opening line of the mxModel statement.

With the update of 6.14

Not sure why; debugging now.

On euterpe I tried source('[secret url]') from R connected over ssh, and I got the warning and the error:

Warning message:
In getDependencies(pkgs, dependencies, available, lib) :

Error in library(OpenMx) : there is no package called 'OpenMx'

See http://openmx.psyc.virginia.edu/thread/160 as well.
