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

I am trying to calculate quantiles of a data frame column split up by two factors: # Calculate the quantiles quarts = tapply(gdf$tt, list(gdf$Runway, gdf$OnHour), FUN=quantile, na.rm = TRUE) This does not work: > quarts 04L 04R 15R 22L 22R 27 32 33L 33R 0 NULL Numeric,5 NULL Numeric,5 NULL Numeric,5 NULL Numeric,5 NULL 1 NULL Numeric,5 NULL Numeric...

Peter, that finally worked. hrs = seq(1, 24, 1) g = bwplot(tt~OnHFact |Runway, data=gdf, ylab="Taxi time (min)", main=title, xlab="Hour of day", par.strip.text=list(cex=0.7), rot=90, xlim=c(0, 25), drop.unused.levels=FALSE, scales=list(x = list(rot=90, cex=.6 ,at=hrs, labels=hrlabs )), panel = function(x, ...) {...

...outfile = paste("../", airport, "/", airport, "taxiHistogram", gate, ".pdf", sep="") pdf(file = outfile, width = 10, height=8, par(lwd=1)) title=paste("Taxi time for Arrival Gate", gate, "by Runway at", airport) gdf = mdf[mdf$ArrivalGate == gate, ] gdf$tt= gdf$TaxiTime/60 histogram(~(gdf$tt) | gdf$Runway, data=gdf, type="count", ylab="Count", breaks=20, main=title, xlab="taxi time (min)", par.strip.text=list(cex=0.7)) dev.off() }...

I am student in Iran(IUT) that work on R software as my project. I need to some data frames in version 1.7.0, but these are not available. please help me.

...ticks are unchanged and the plot looks worse (because of no distances to the border of the Panels). EXAMPLE: -- # begin example library(lattice) library(nlme) # create sample data set.seed(123) ID<-rep(1:6, each=4) Time<-rep(c(0,6,12,24), 6) Y<-runif(24) DF<-data.frame(ID, Time, Y) GDF<-groupedData(Y ~ Time | ID, data=DF) plot(GDF,layout=c(3,2), aspect=0.6, xlab="Months") # end example QUESTION: How can I get tick marks at 0, 6, 12, 18, 24 on the x-axis? Any help will be appreciate. Karl. PS: Have a happy new year and keep R running!!

In the name of Allah. hello, how are you? I sent a mail for you,yesterday but I didn't recieve to my aim. I need to some data frames in version 1.7.0 such as "florida","Barley","rainforest" and some others. I don't know these data frames are in which library. I typed "data(package = .packages(all.available = TRUE))" that was in "data()"

I typed 'help.seaech("dolphins")' but the response was "No help files found with alias or title matching 'dolphins' using fuzzy matching.". what is "fuzzy matching" and how can I find these

Dear all, I am searching for a possibility to view large data sets (e.g. stored in ffdf objects) in a GUI window in a memory-efficient way. So far I looked at gtkDfEdit (package RGtk2Extras) and gdf (package gWidgets). Both operate (as far as I can see) on data frames stored in memory. gtkDfEdit accepts an ff data frame as input, but there is a long delay before it shows up, so I presume the data is converted to an in-memory data.frame beforehand. Ideal would be a solution similar to JTab...

Looking for a little help, please. A contact from Oracle (Sun) suggested I pose the question to this email. We''re using ZFS on Solaris 10 in an application where there are so many directory-subdirectory layers, and a lot of small files (~1-2Kb) that we ran out of inodes (over 30 million!). So, the zfs question is, how can we see how many files & directories have been created in

Dear all, I posted this problem sometime back on 0.9.26 (http://www.winehq.com/pipermail/wine-users/2006-December/024086.html). I thought the problem was fixed, but it seemed not. >From 0.9.26 all the way to the latest 0.9.30, I've been seeing this problem on my system (Linux flying 2.6.17-11-generic #2 SMP Thu Feb 1 19:52:28 UTC 2007 i686 GNU/Linux; Ubuntu Edgy installed, but running

Hello, Is there an accepted way to convey, for regression trees, something akin to R-squared? I'm developing regression trees for a continuous y variable and I'd like to say how well they are doing. In particular, I'm analyzing the results of a simulation model having highly non-linear behavior, and asking what characteristics of the inputs are related to a particular

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
