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.

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