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

I have a dataset of about 10^6 rows, each consisting of a timestamp, several factors, a string, some integers, and some floats. I'd like to graph this data in various ways, including straightforward ones (how many events per week over the past year for each of 4 values of some factor), some less straightforward. I've managed to do this by brute force, but I'd like to learn how to do

Hi, I currently use? Asterisk 1.0.7-BRIstuffed-0.2.0-RC7k on a debian sarge with a kernel 2.4.27 on a P4 3Gig with 1Gig of memory When i use i4l on any call, the called party ( on the telco operator side ) ear me with a delay of 1 sec after 1 minutes , 2 sec after 3 minutes and so on... After a quart hour, the delay make the conversation just

Hi all I have some tick-by-tick data and I have calculated the intraday returns. I want to sum up the intraday squared returns to calculate the daily volatility(or daily variance). I know that the s-plus FinMerics has the function aggregateSeries function that can be apply to daily data: aggregateSeries(x, Fun, by="daily"), but the counterpart function in R:applySeries can not be apply

Hello, I would like to create lagged and delta variables from a set of variables and then add them to a dataframe Suppose that GDPPcSa is a variable. I would like to be able to do this QuarterlyData$D1GdpPcSa = diff(GDPPcSa , 1) in an automated fashion so that I loop over Quartely data to compute the first difference of its variables and add them to the dataframe. .It would be great to get a way to create the string "D1GdpPcSa" knowing that the name of the var is GdpPcSa. Then I can add the varibale D1GdpPcSa to the dataframe and work on its names attribute. Th...

Hello, Is there any way to specify which pubkey has rights to use the sftp-server subsytem when this has been set up in the sshd server? I don't know if I could control which users are authorized to use the sftp-server, could I? Is there any official patch that allows sftp-sessions 'chroot'ed? Thanks in advance. -- Best regards, quart mailto:quart at

I'm trying to plot a time series (quarterly observations, seasonal effect, T=56),regression line and predicted point on the same plot. I'm using following commands: > plot(qdts,xlim=c(1982,1997)) > lines(fitted(m2)~time,data=qd,col="red") > points(predict(m2,newdata=nqd),col="blue") where: qdts<-ts(qd$durables,start=c(1982,1),freq=4)

I sent a message a couple days ago about doing calculations for power of the ANOVA. Several people got back to me very quickly which I really appreciated. I'm working now on a similar problem, but instead of a balanced ANOVA, I have an unbalanced one. The first part of the question was: You assume that the within-population standard deviations all equal 9. You set the Type 1 error rate at á

R 2.6.0 Windows XP At the risk of raising the ire of the R gods . . . I am looking for a package that will allow me to perform a poisson, quasipoisson, or negative binomial regression with adjustment for repeated measures. I have looked at glm, it does not appear to allow repeated measures. Although I can't get any help for lme or lme4 I remember that those packages perform repeated measures

Greetings R users, My goal is to generate quartile groups of each variable in my data set. I would like each experiment to have its designated group added as a subsequent column. I can accomplish this individually with the following code: brks <- with(data_variables, cut2(var2, g=4)) #I don't want the actual numbers, I need a numbered group data$test1=factor(brks,

Hi, This is not a DTrace technical question (so, please don''t flame me for it) :) This is regarding the DTrace (un)conference TShirt. I am curious to know what engine is it. Could not figure it out.

I''ve inherited an EAV database and there''s really no option to remodel it. Data is stored as key_name, key_value pairs Trying to return a meaningful, unified recordset is far too complex to be efficient. I''ve decided to make use of the MySQL GROUP_CONCAT, and CONCAT_WS functions to return a fast query result, with the consolidated fields as one string. The final data is

Hi, Without trying to print 1000000 points (see <http:// finzi.psych.upenn.edu/R/Rhelp02a/archive/42105.html>), I often print maps for which I do not want to loose too much of coastline detail, and/or plots with 1000-5000 points (yes, some are on top of each other, but using transparency (i.e. rgb colors with alpha information) this actually comes through as useful information.
