Dear kind R helpers, I have a vector of runway names in rwy ("31R", "31L",... the number is user selectable) arrgnd is a data frame with data for all flights and all runways, with a Runway column. I am trying to subset arrgnd into a dat frame for each selected runway, and then combine them back together using the follow...

I have a data frame (attached) that has interpolated EOT errors for each minute before flight landing.

I am using ggplot2 to make a boxplot that overlays a scatterplot: pp = qplot(time, error, data=times, size=I(1), geom="jitter", main=title, ylab="Error (min)", xlab="Time before ON (min)", alpha=I(1/10), color=times$runway, ylim=c(-30,40)) pp2 = pp + with(times, facet_wrap(~ runway, ncol=2)) print(pp2 + geom_boxplot(alpha=.5, color="blue", outlier.colour="green", outlier.size=1)) The x variable is a factor for every minute from 0:60. My problem is that ggplot2 labels every factor v...

Dear R-Help, With the attached data set, I am still getting incorrect bwplots > xyplot(gdf$tt~gdf$OnHour |gdf$Runway, data=gdf) # Is correct > bwplot(gdf$tt~gdf$OnHour |gdf$Runway, data=gdf, horizontal=FALSE) # Puts the boxes on the wrong x-axis values # look especially at 0 and 3. How do I fix this? What is happening? Thanks, Jim Rome

In my main R program, I have source("retaanalysis/Functions/doAirport.R") .... stuff to read data and calculate ads sapply(ads, function(x) {doAirport(x, base)} ) And doAirport has # analyze the flights for a given airport doAirport = function(df, base) { # Get rid of unused runway factor levels (from other airports) df$lrw <- drop.levels(df$lrw) # In gdata package # Drop messages from after the landing time df = df[df$PredTime >= 0.0,] airport = as.character(df[1,"Dest"]) #print it out airport date = strptime(df[1,"on"],...

Dear all, I like tinc and am using it widely in the company I work for. Currently I'm experimenting with 'switch' mode & have a problem with packets being forwarded. I've tried possible combinations with next parameters: a) Broadcast = direct b) Forwarding = kernel c) DirectOnly = yes From the documentation, it looks like (a) should be enough to stop packet forwarding

I am just getting off the ground with RoR. (actually just walking out to the runway) I want to setup a development / test environment as close to the production environment as possible except for OS (Win XP for Dev, Linux for Prod).

Dear R-user, I already received quite a lot of replies to this mail and like to do a preliminary sum up. A few were sceptical about the use of such a beginner mailing list. The arguments were that people starting with R will only stay subscribed for a short time until they reached the R-help "level" and therefore only beginner will teach beginner how to use R. But as far

Hello, I am building a home file server and am looking for an ATX mother board that will be supported well with OpenSolaris (onboard SATA controller, network, graphics if any, audio, etc). I decided to go for Intel based boards (socket LGA 775) since it seems like power management is better supported with Intel processors and power efficiency is an important factor. After reading several

Hello Everyone,   Learning about R and its wonderful array of functions. If it's not obvious, I usually try to find out what a function stands for. I think this helps me remember better.   One function that has me stumped is "sink." Can anyone tell me if this stands for something?   Thanks,   Paul         __________________________________________________ [[alternative HTML
