Hi R community, I'm just starting out in R and have a basic question about xyplot and tables. Suppose I had a table of data with the following names: Height, Age_group, City. I'd like to plot mean Height vs Age_group for each City. When I try to do the following: > library(lattice) > xyplot(mean(Height) ~ Age_group | City) of course I get just one data point, the mean Height for

Hoping someone can help me with xtabs and ftable. I'm trying to get a pair of ftables (possibly more) next to each other. For example: > dunhill_lights_xtab<-ftable(xtabs(grossedupobs ~ gender+age_group + dunhill_lights, data = ciggs)) > dunhill_lights_xtab dunhill_lights No Yes gender age_group Female

I am using the following code to produce a graphic: library(lattice) postscript("figs%03d.eps", width = 6.0, height = 6.0, ?????????? horizontal = FALSE, onefile = FALSE, paper = "special") xyplot(cases~yr|agrp*sex,data=data[tse==0 & expgrp==1,], groups=source, pch=".", type="l", ?????? main="Exposure group 1, time since entry 0") The

Hi List, My goal is to force R not to print in scientific notation in the sixth column (rel_diff - for the p-value) of my data frame (not a matrix). I have used the format.pval () and printCoefmat () functions on the data frame. The R script is appended below. This issue is that use of the format.pval () and printCoefmat () functions on the data frame gives me the desired results, but coerces

I''m working on a fairly complex join query and could use a bit of advice from more expert users of ActiveRecord. I have an events table with quite a lot of data, with has_many relations to categories, age_groups, and event_images. In my first naive implementation, each event had a date, so to load all upcoming events efficiently, I''d do: Event.find(:all,

I am having a problem with an assignment to an object stored in session. for example when I am in console o = NewOrder.new # dl = DeliveryLocation.new # o.delivery_location = dl #=> returns a delivery location object # o.delivery_loaction.save #=> returns true when I am using the controller delivery_location = DeliveryLocation.new(params[:delivery_location])

Hello all, I'd like to update my local src tree (from Wine 20040615), and I'd rather grab a diff instead of the full 10MB so tarball; the README in source.winehq.org refers to some 'Wine-yymmdd.diff.gz' but I can't find any of such. Did I overlook some infos, or are such diffs not available, and I'm supposed to use CVS? thanks -- paolo GPG/PGP id:0x21426690 kfp:EDFB

1. What does ~ mean? cd ie. "~/.wine/drive_c/" 2. Steam runs. Hurray. But I can't chat with friends. I can see their messages, but not mine. I assume they never get them because they never say anything more. 3. I launch TF2, I get the valve logo, source logo, then BAM back to desktop. No error boxes. And my screen resolution stays "minimized" to what tf2 was
