Description
Hey I'm working on something and came upon a bug. I boiled the problem down to the following. If I run the following code, it works fine. But if I run the latter code with a simple for-loop in the UDF, I get an error. This actually may be the same case with any loop. Please see below. I also included the error message.
discrete_samples = function(matrix[double] weights) return(double ix){ ix = 0.00 } weights = matrix(1, rows = 5, cols = 1) ix = discrete_samples(weights) print("Index here: " + ix)
discrete_samples = function(matrix[double] weights) return(double ix){ ix = 0.00 for(j in 1:5){ print("Hello") } } weights = matrix(1, rows = 5, cols = 1) ix = discrete_samples(weights) print("Index here: " + ix)
