Dataframe Manipulation
Hello Ulrik,
Can you please explain this code means how and what this code is doing
because I'm not able to understand it, if you can explain it i can use it
in future by doing some Lil bit manipulation.
Thanks

group_by(Purchase_ID) %>%
do(split_items(.))

RFM Analysis Help
I'm trying to perform a RFM analysis on attached dataset,
i'm able to get the results using the auto_rfm function but i want to
define my own breaks for RFM,
when i tried to define my own breaks i got the identical result i.e 111 for
every ID.
please help me with this with working R script.
Thanks

Dataframe Manipulation
Hi Hemant,
the solution is really quite similar, and the logic is identical:
library(readr)
library(dplyr)
library(stringr)
library(tidyr)
data_help <- read_csv("data_help.csv")
cat_help <- read_csv("cat_help.csv")
# Helper function to split the Items and create a data_frame
split_items <- function(items){
x <- items$Items_purchased_on_Receipts %>%

How to define proper breaks in RFM analysis
hello,
I'm confused what you guys are talking about.
i just want to set ideal threshold values for my RFM scores which can be
done using Quantiles but i don't want to use quantiles because my data is
not normally distributed so it will lead to wrong ranges of breaks. to fix
this problem I'm looking for an approach which can define the ideal range
to breaks to categorize RFM scores into

How to define proper breaks in RFM analysis
Hemant's problem is that the indicators are not distributed uniformly.
With a uniform distribution, categorization gives a reasonably optimal
separation of cases. One approach would be to drop categorization and
calculate the overall score as the mean of the standardized indicator
scores. Whether this is an option I do not know. I did offer an
"eyeball" set of breaks in a previous

RFM analysis
Hi Hemant,
Let's take it one step at a time. Save this code as "qdrfm.R" in your
R working directory: It includes the comments I added last time and
fixes a bug in the recency scoring.
qdrfm<-function(x,rbreaks=3,fbreaks=3,mbreaks=3,
date.format="%Y-%m-%d",weights=c(1,1,1),finish=NA) {
# if no finish date is specified, use current date
if(is.na(finish))

Help RFM analysis in R (i want a code where i can define my own breaks instead of system defined breaks used in auto_RFM package)
I seriously doubt that you are running the code I sent. What you have
probably done is to run your data, which has a different date format,
without changing the breaks or the date format arguments. As you
haven't provided any example that shows what you are doing, I can't
guess what the problem is.
