Challenge #131: Think Like a CSE... The R Error Message: cannot allocate vector of size...

 

Sorry, I sent by Mistake, I should send it someone else, accept my apology.   

 

 

Hi @PhilipMannering

 

I tried to practice your solution because I have the same problem but related to (Lenier regression), I noticed you used the Generate rows tool, As I understand it will create a new field if the number of rows reached 1000,000 but what does this mean? what it is useful for ? how it solves the problem of memory limitation? please explain more.

 

Note: After a while (around 7 minutes) when running your workflow My device halted and not responding !!??

For the particular problem of the coworker, the data size seems to be too big to handle. Connect from Select Tool to remove some fields may be able to solve the problem.

For my R error, the problem is field type mismatch. Connecting from Select Tool also solve the problem.

Hi! Here my solution :)

So, if 3M rows were a problem...let's divide the problem by 15 ;)

Just had a very similar problem, and even after reducing the number of fields and optimizing data types memory limit was exceeded, so I finally tried to solve this challenge ...

Chose to get the necessary data directly from the K-Centroids Cluster Analysis tool instead of using an Append Cluster tool. Assuming that the K-Centroids Cluster Analysis tool works, hopefully my solution would be a more optimised way of obtaining the data.
