FBI Homicide data?
Dear all, do you know if it's available and where the "FBI Homicide" dataset? It has at least the following columns: "victim age", "homicide age". A scatterplot of this data is visible here: http://www.uml.edu/gallery/main.php?g2_itemId=6016 Thanks for your help! mario -- Ing. Mario Valle Data Analysis and Visualization Group |

inconsistent output using 'round'
I am hoping for some advice regarding limiting decimal points to 3. 'Round' produces the desired results except for the 97.5% confidence interval. Any advice as to how I modify the code to obtain output to 3 decimal points for all ouput is appreciated, regards Bob Green mod.multgran <-multinom(offence ~ grandiose * violent.convictions, data = kc, na.action = na.omit)

Graphs in Windows 95/95
Dear R-Listers, I'm a new R user and I've got some problems with copying/saving graphs in Windows Metafile Format. If I copy a graph from the R window (in Enhanced Metafile Format) and then paste it in WinWord 95, then everything is fine, apart from the fact that a) lines become a little bit thicker when the graph is printed; and b) dotted lines loose a little bit of resolution. However,

Multiple plots
Hi, I would love to make multiple histograms transposed one on another in order to show relation between the sets. I tried to write a function like this, but R tells me, that I cannot use add=FALSE in high-level commands. That's nice but I am supposed to do? rm(list=ls()) # what's wrong with underscore? #getwd("/home/matej/docs/skola/stat\_anal-cj3534/assign01/")

Cross K Ripley's function and "spatio-temporal interaction power"
Dear All, I have a collections of spatial data. I have to analyze pairs of these point patterns to test their spatial interaction. I was moving towards the cross K Ripley's function. The problem, however, are the following: 1) What is the best way to get a single real value that represents the interaction "power"? 2) How to obtain a value that even allows me to rank the pairwise

fitted probabilities in multinomial logistic regression are identical for each level
I was hoping for some advice regarding possible explanations for the fitted probability values I obtained for a multinomial logistic regression. The analysis aims to predict whether Capgras delusions (present/absent) are associated with group (ABH, SV, homicide; values = 1,2,3,), controlling for previous violence. What has me puzzled is that for each combination the fitted probabilities are

constructing a dataframe from a database of newspaper articles

Each record includes specific labels/field names (a sample of 1 record (one of the longest ones) is below - at end of post. What I want to do is reformat the data, so that each individual record becomes a row (some cells will have a lot of text). For example, the column

replicating the odds ratio from a published study- post # 2
Peter & Michael, I just came across the following on another mailing list and realized that my use (and the authors of the article use of the term 'odds ratio' ) is probably incorrect. I believe my interest is in the 'odds' of schizophrenia among the population of homicide, rather than a comparison of odds . "Yours seems a good idea, Kevin, if you are only interested

Using coxph with Gompertz-distributed survival data.
Dear list: I am attempting to use what I thought would be a pretty straightforward practical application of Cox regression. I figure users of the survival package must have come across this problem before, so I would like to ask you how you dealt with it. I have set up an illustrative example and included it at the end of this post. I took a sample of 100 data points from each of two populations

Array as time series?
Dear R-helpers, I have 4-dimensional atmospheric data (x,y,z,t), which I want to analyse on spatio-temporal diversities. As far as I understand there only exists the possibility to construct time series as two-dimensional matrices (mts). For the moment, I hold it in different objects: 1. a four-dimensional array for the spatial related analyses 2. a two-dimensional mts timeserie, which was
