markovchainFit
with method="bootstrap
fails on Apache Spark
@ncordon do you have an idea about it? |
Upps, sorry, I missed this one. No idea @spedygiorgio, I have never worked with Spark. I can mark it as low priority right now until I can allocate a slot of time to look into it |
Neither I did. We will keep in hold for now |

I know the
markovchain
package wasn't designed with Spark in mind, but I wondered if you had any ideas about how to solve a problem I am having with this package on Spark.This example code runs perfectly fine from the R console on Mac OS X and Centos 7.
When run on Spark via Apache Zeppelin (on Centos 7), the MLE and MAP methods are estimated without problem. However, the bootstrapped method fails and gives this error:
Error in (function (classes, fdef, mtable) : unable to find an inherited method for function 'sample' for signature '"character"'
Do you have any ideas on how I can solve this problem?
Many thanks for a great package!
