Is there an optimal / minimum sample size for attempting to construct a classification tree using /rpart/? I have 27 seagrass disturbance sites (boat groundings) that have been monitored for a number of years. The monitoring protocol for each site is identical. From the monitoring data, I am able to determine the level of recovery that each site has experienced. Recovery is our

Hi, I am working on problem 2 of Chapter 8 in Data Analysis and Graphics Using R and don't know how to approach the second half of the question: In the data set (an artificial one of 3121 patients, that is similar to a subset of the data analyzed in Stiell et al., 2001) head.injury, obtain a logistic regression model relating clinically.important.brain.injury to other variables. Patients

Hi all, Is it possible to use HTML area objects from an image map as droppables for a drag/drop interface? I want to get a different response depending on which part of an image I drop a draggable div object on. The context is creating an incident report form where injuries can be dragged onto a body sketch. I''ve tried this using the code below. However, the droppable is always identified as "front_head", the first area object, no matter which part of the image is dropped on. Has anyone managed to get this working successfully? Many thanks, Adam...

I’m trying to export a file from R to excel using the xlsReadWritePro function and I keep getting the error below. I get the same error when I use the oledatetime function. My current date format is mm/dd/yyyy, which is how I want it in excel. Also is there anyway to export different datasets to multiple sheets similar to the ods function in SAS? <?xml:namespace prefix = o ns =

Hello everybody, I'm testing the randomForest package in order to do some simulations and I get some trouble with the prediction of new values. The random forest computation is fine but each time I try to predict values with the newly created object, I get an error message. I thought I was because NA values in the dataframe, but I cleaned them and still got the same error. What am I

Hi, I am using GAMMs to show a relationship of temperature differential over time with a model that looks like this:- gamm(Diff~s(DaysPT)+AirToC,method="REML") where DaysPT is time in days since injury and Diff is repeat measures of temperature differentials with regards to injury sites compared to non-injured sites in individuals over the course of 0-24 days. I use the following

...t. I actually would prefer to change it to a dataframe but if someone can show me how to convert it to a matrix, then as.data.frame will work on that. I was thinking about just changing the class to matrix since table looks very similar to a matrix but I wasn't sure if that would cause side injuries. thanks. temp <- structure(c(0.345901639344262, 0.360117302052786, 0.354304635761589, 0.354319180087848, 0.365524402907580, 0.359455958549223, 0.340284360189573, 0.369763205828780, 0.304918032786885, 0.304985337243402, 0.310596026490066, 0.287457296242069, 0.285565939771547, 0.26424870466...

I want to eliminate certain observations in a large dataframe (21000x100). I have written code which does this using a binary vector (0=delete obs, 1=keep), but it uses for loops, and so it's slow and in the extreme it causes R to hang for indefinite time periods. I'm looking for one of two things: 1. A document which discusses how to avoid for loops and situations in which it's

Hi *, I have been using radrails as an IDE for awhile now and we were getting along just fine - but recently it has just gone totally postal?!?? I created a new rails app - when I click to expand the folders there is no framework in place, just the root folder of the app. To add insult to injury two weeks of work also just disapeered - I kid you not just gone without any deletion on my part.

Processing Conflict: speexdsp-1.2-0.9.rc3.el6.x86_64 conflicts speex <= 1.2-0.21.rc1 I am loath to replace things on my primary workstation as I have far too much to do as it is without dealing with self-inflicted injuries. However, I do use Jitsi as a softphone and the latest version has a dependency on a package in EPEL which replaces something from the base distro. Can someone inform me of what issues, if any, would replacing speex with speexdsp likely cause? I have a lot of packages that depend upon speex. I...

In configure.in, there is a check that does `krb5-config --version | grep -v 1\.2`, making sure there is no "1.2" in the version of Kerberos in use. This is to prevent compiling against MIT Kerberos version 1.2, which is too old for Dovecot. Unfortunately for this idea, Heimdal 1.2.1 is out. And Dovecot builds fine against it. Whoever committed this check also appears to have removed

Hello R masters, This request is being made after searching through archive mailing list. I have a "many" table in a medical application where each injury a person suffers is recorded as a separate row. In my toy example below it means respondent #1 had three injuries and so on. If x2 equal 2 then I want to delete all the rows for that person from the dataframe--see Before and After below. I have thought about using match to first identify the IDs that have a 2 in x2 and then in a second step delete all rows that have matching IDs with this subset, but I hav...
