[R] error with source(): invalid 'times' value

[jim holtman]

It sounds like you have some invalid expressions.  Dump out the values
of 'leading' and 'length(dep) - leading'.  Learn some simple debugging
techniques.  One is to set

options(error=utils::recover)

so that on the error you can use the browser to examine what the values are.
