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.
Thank you
John

Error in rep(0, ncol(fx)) : invalid 'times' argument
