Dear Forum, Which functions and packages should be installed to make work the function "relevel"? treatment<-revel(treatment,ref="Db") Error: no se pudo encontrar la funci?n "revel" Thank you very much for your help, Xavier Chiriboga M.

I have a personal apache/mail server that is getting hacked and I'm not sure how the person is getting in. What's happening is that every few days, the below script will show up in /tmp as 'dc.txt', owned by apache and then a TON of mail is queued up to a bunch of addresses in @uol.com.br. I initially thought they got in becuase I had an outdated version of 'gallery'

Starting a new Xen setup, with off-the-shelf Wheezy, and the standard Xen packages, which turn out to be Xen 4.1 I used to just put a (network-script network-bridge) in the Xen setup, but I guess you can''t do that anymore... There are a variety of recipes to setup the network and bridging, since apparently the Xen setup doesn''t does this for you anymore. I''ve gone

Dear R users I wondered if any of you ever tried to calculate distance matrix with very large data set, and if anyone out there can confirm this error message I got actually mean that my data is too large for this task. negative length vectors are not allowed My data size and code used dim(mydata_nor)[1] 365000 144> d <- dist(mydata_nor, method = "euclidean") Here my

To the R developers, The discussion below reminded me that I think it might be a good idea to take the Relevel function from the Lexis package and replace relevel in stats with it. This is really nothing special for epidemiology. It is fully compatible with the existing relevel (it actually contains the relevel code almost verbatim as a subset), but it has the extra functionality of combining

Dear list, I am running R code which produces a data.frame with variable rows. For plotting purposes I need to relevel the column called "names" but since the dimension of the data.frame can vary I do not know how to dynamically revel the data.frame. Here is an example data.frame called df to illustrate what I try to achieve: > df <-

Something that bit me: The function relevel takes a factor, and a reference level to be promoted to the first place. If ?ref? is a character this level is promoted, if it?s a numeric the ?ref?-th level is promoted. Which turns out to be very confusing if you have factor with numeric values (e.g. when reading in a csv with some dirty numeric columns and stringsAsFactors TRUE) For example:

Dear list, I'm having second thoughts after solving a very trivial problem: I want to extend the relevel() function to reorder an arbitrary number of levels of a factor in one go. I could not find a trivial way of using the code obtained by getS3method("relevel","factor"). Instead, I thought of solving the problem in a recursive manner (possibly after reading

Hi, I have a question about estimating IRT models by using nlme, not just rasch model, but also other models.
