[R] Error: vector memory exhausted (limit reached?)

[Olivia Keefer]

Hello!

My colleague and I have continually run into this error and would like to 
better understand why and how to remedy. We have been able to run other 
regressions, but when we go to run a certain set of variables, we both are 
getting this message each time we try.

Any insight would be helpful as to 1) why and 2) how to remedy.

Attaching our package as well here if it is helpful:



#This loads the required package. Always select UK Bristol as a CRAN MIRROR / 
LOCATION

#1. Highlight the below code and run (3rd icon or right click)



require(relaimpo)

install.packages('relaimpo',dep=TRUE)

install.packages('iterators')

install.packages('foreach')


Thanks!

Re: [R] Defining Parameters in arules

[Tom Woolman]

Greg Williams has a book titled "Data Mining with Rattle and R", which 
has a chapter on association rules and the arules package. Williams' 
Rattle GUI package for R also lets you define an association rules model 
using a graphical interface (which creates the R code for you in the log 
file for Rattle). I use this textbook in one of the MS-level R courses 
that I teach and found it to be a good way to convey these concepts 
especially for those new to R and AI/ML generally.

Re: [R-es] reemplazar valores de una variable por otras

[Griera]

Muchas, gracias Javier:

Independientemente del rendimiento, me apunto esta solución. Es muy clara, y yo 
nunca trabajo con tablas de billones de registros.

Gracias por siempre ayudar y saludos.

[R] Defining Parameters in arules

[Stephen H. Dawson, DSL via R-help]

Hi,


New to the list, first post.

I have reviewed the file:
https://cran.r-project.org/web/packages/arules/arules.pdf

I am unable to find what I am after, so I am asking the mailing list for 
assistance, please.


I am using arules to accomplish apriori for reviewing some association 
rules work output from a colleague. I have validated I have the exact 
same output as my colleague in the syntax I am running. However, I read 
my colleague has ext listed as FALSE in their parameter specification. I 
would like to set my ext to FALSE on my end, as it is set to TRUE now.


QUESTION
What is the syntax to set my apriori parameter specification for ext to 
FALSE?


Thank you in advance for your assistance.


Kindest Regards,

Re: [R] Date read correctly from CSV, then reformatted incorrectly by R

[peter dalgaard]

It reads other formats _if you specify them_. After all, no computer (or human) 
can tell whether 11/03/1959 is November 3 or March 11 without further hinting. 
So it tries the two ISO-like formats and leaves other cases for the user.
