[R] sim() not working in example given in lava() documentation - please help.
Dear All, I am trying to simulate using a statistical model created in the lava() package. My model gave the error message "Error in rep(0, ncol(fx)) : invalid 'times' argument". So, I used the example in the documentation for the lava() package - v1.4.4, on page 79; this is copied below with the output. It did the same thing. I can plot and view the model, so it appears to have been created correctly. I am relative new to this, so don't have a good idea of where to start when a standard example fails like this. I have tried naive fiddling with the code, and Googling. Any advice would be much appreciated.

Hi
I do not know anything about lava, however this
m <- lvm(y~x+z)
regression(m) <- x~z
distribution(m,~y+z) <- binomial.lvm("logit")
d <- sim(m,1e3)
head(d)
y x z
1 1 1.0033540 1
2 0 0.3834120 0
3 1 -0.3737790 1
4 1 -1.2927288 0
5 0 -0.4242461 1
6 0 -1.8349548 0>
gives me some result without any error.
So obviosly something is broken in your side. Try to start clean R session and
try this code again.
Cheers

[R] sim() not working in example given in lava() documentation - please help.
Thank you very much Petr! An external check like you did really helps.
After shutting down, I've started new session and project in a different
directory and it's working.
I will know next time that with R a full "turn it off and turn it on
again" can make a difference even when I can't see why it should :-)
