Hi R users! I'm new to R, so I'm starting with a basic exercise in rpart. I'm predicting if a user will churn based on past order history. I've calculated the probabilities in excel, and if user is a single order customer (1), then their probability of churn is 90%, if there are multiple

Hi Marc, Pre-compiled RPMs for R are up to 3x slower than "self-compiled" R using Intel MKL. Yes, I do know about Microsoft R Open, but it wants to overwrite the default /usr/bin/R and I have AMD machines in my cluster, which cannot run MRO. So, I want to do my own compilation and install R in a

You will generally get a better response if you create a data set that we can test our ideas on. You sketched out the data but your final results include meal combinations that are not in your Meals data frame. Also using dput() to provide the data makes it easier to recreate the data since

[R] Compiling R with zlib in non-standard location

Hi all, I am trying to compile R 3.4.0 on a RHEL 6.5 system. R requires a newer version of zlib than is standard on RHEL 6.5. I do have a newer version that satisfies R's requirement, but the configure script gives no way of specifying a non-standard location of zlib. Is there a way around this?

[R] Fitdistrplus and Parameter Constraints

Dear All, In principle it is a simple question, but not idea about how to tackle it. Suppose you have a distribution depending on two parameters, e.g. beta(a,b). For some reasons, you want to impose that the two parameters of the beta distribution are identical, i.e. you want to fit your data to

Hi, Actually, you don't need to create the column first, nor to use which: DF[DF$month==1, "product1_1"] = DF[DF$month==1, "product1"] * 3.1 The "[" is a great tool that you need to learn. In this case, you don't need to combine "[" and $: within the square brackets, the vector before the

Re: [R] About change columns and specific rows in R

Hi Lily, You're on the right track, but you should define a new column first (filled with NA values), then specify the precise rows and columns on both the left and right hand sides of the assignment operator that will be altered. Luckily, this is pretty easy...just remember to use which() on the
