Hi, I'm analysing some anthropometric data on fifty odd skull bases. We know the gender of each skull, and we are trying to develop a predictor to identify the sex of unknown skulls. Rpart with cross-validation produces two models - one of which predicts gender for Males well, and Females poorly, and the other does the opposite (Females well, and Males poorly). In both cases the error

I have a dataset relating the effects of engineering works on the level of salinity in a river before and after the works. I have modelled this using linear mixed effects models to determine if the significance and level of the response to the works. I am wanting to calculate the se of difference at several points. I am not sure of how to calculate the difference and which estimate of se I

I have a dataframe that contains time values in the form of yyyy-mm-dd hh:mm i.e. 2010-07-14 13:00. When I convert this to numeric via tvec <- as.numeric(Time) I get a number that is in seconds. So far so good. When I then divide the numeric value by the number of seconds in a day eg tvec/(60*60*24) I only get integer values and not fraction of a day which is what I want. What do I need to

Hi, I think I'm missing something very obvious, but I am missing it, so I would be very grateful for help. I'm using rpart to analyse data on skull base morphology, essentially predicting sex from one or several skull base measurements. The sex of the people whose skulls are being studied is known, and lives as a factor (M,F) in the data. I want to get back predictions of gender, and

Hi, The subject says it all. On my "server" machine in the local LAN (192.168.1.252 in a 192.168.1.0/24 network), I setup Bind. I installed the 'caching-nameserver' package, which provides a set of configuration files for Bind so it can be used as a caching nameserver out of the box. On the server : I start bind (service named start), and try it out. # host www.google.fr

Hi, Rsync is a fantastic program, and it does everything we need in terms of file transfer and syncing source and destination file directories. We do have a situation now where we need rsync to transfer the files once only from the source directory. Please let me briefly explain using a simple generic exmple: 1. At t0, we transfer f0 location A to location B 2. At t1, 10 new
