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'm getting all the rows as NA in Cscore and almost most of the
observation in R and F and M are also NA.
what can be the reason for this. also suggest me the appropriate solution.

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)
Hi Hemant,
Here is an example that might answer your questions. Please don't run
previous code as it might not work.
I define the break values as arguments to the function
(rbreaks,fbreaks,mbreaks) If you want the breaks to work, make sure that
they cover the range of the input values, otherwise you get NAs.

# column 1 is customer ID,

Hello Jim,
i have converted all my variable data type according to your attached
example including date, and my dataset looks like this.
ID purchase date

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.

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'm trying to perform an RFM analysis on the attached dataset,
I'm able to get the results using the auto_rfm function but i want to
define my own breaks for RFM.
as follow
r <-c(30,60,90)
f <-c(2,5,8)
m <-c(10,20,30)
but when i tried to define my own breaks i got the identical result for RFM
i.e 111 for every ID.
please help me with this with working R script so that i can get

Custom colourkey spacing in levelplot, contourplot
Dear R gurus,
I have got stuck on how to customise the colorkey generated by
levelplot and contourplot, in the lattice package. This best
illustrated by an example:
library(lattice)
levelplot(volcano^20/1e45,at=c(0,0.001,0.01,0.1,1,10))
The reason for raising the volcano dataset to the 20th power is to
create a dataset with a large vertical exaggeration - this is similar
in nature to the data

Hi guys,
I want to transfer the following code from R into .Call compatible form. How
can i do that?
Thanks!!!

for(i in 1:sim){
if(i>2) genemat <- genemat[,sample(1:ncol(genemat))]
ranklist[,1] <- apply(genemat, 1, function(x){
(mean(x[cols]) -
mean(x[-cols]))/sd(x)})

standardized residuals (rstandard & plot.lm) (PR#8367)
Full_Name: Heather Turner
Version: 2.2.0
OS: Windows XP
Submission from: (NULL) (137.205.240.44)
Standardized residuals as calculated by rstandard.lm, rstandard.glm and plot.lm
are Inf/NaN rather than zero when the un-standardized residuals are zero. This
causes plot.lm to break when calculating 'ylim' for any of the plots of
standardized residuals. Example:

standardized residuals (rstandard & plot.lm) (PR#8468)
This bug is not quite fixed - the example from my original report now =
works using R-2.2.1, but
plot(Uniform, 6)
does not. The bug is due to
if (show[6]) {
ymx <- max(cook, na.rm =3D TRUE) * 1.025
g <- hatval/(1 - hatval) # Potential division by zero here #
plot(g, cook, xlim =3D c(0, max(g)), ylim =3D c(0, ymx),=20
main =3D main, xlab =3D

survival - summary and score test for ridge coxph()
It seems to me that summary for ridge coxph() prints summary but returns NULL. It is not a big issue because one can calculate statistics directly from a coxph.object. However, for some reason the score test is not calculated for ridge coxph(), i.e score nor rscore components are not included in the coxph object when ridge is specified. Please find the code below. I use 2.9.2 R with 2.35-4 version
