similar to: Converting Variable Name into String

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

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

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

Hello, I am not sold on FileCheck's new behaviour. For failing tests in verbose mode, it first dump the actual error messages, followed by the annotated input file to FileCheck. The result is I can't immediately see error messages if the input is more than just a few lines long, so I have to scroll all the way up to see the errors, then down again, etc. I do see some advantages of

Dear all, I would like to model the relationship between y and x. y is binary variable, and x is a count variable which may be possion-distribution. I think it is better to divide x into intervals and change it to a factor before calling glm(y~x,data=dat,family=binomail). I try to use rpart. As y is binary, I use "class" method and get the following result. >

Hi Everyone, quick question before the end of the year. I have soem indices to select data from a bigger sample. I want to select n days before each index and n days after the index. Any clever way to do it. A for loop would do but I wanted to know if there is a moreR-friendly way to approach this Example # InitialIndices i2 = (90, 190, 290) # Indices I want to end up with i3 = c(85, 86, 87,

Hi I have two date select options in a form, when I try and grab these values using somthing like @pMax = params[:max] I get this in the varibale name max(1i)2006max(2i)6max(3i)5 which has the correct data, jsut with added things like max(1i) Whats the best way of grabbbing this data into a variable without the extra titles?

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, Thanks for responding of gantt charts. but i have some problem regarding with gantt charts. i.e. Ymd.format <- "%Y/%m/%d" Ymd <- function(x){ as.POSIXct(strptime(x, format=Ymd.format))} gantt.info <- list( labels =c("First task","Second task","Third task","Fourth task","Fifth task"), starts

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

Hi everyone, I have the following problem: I have three variables, 'group', 'city' and 'pressure' There is an interaction effect between group and city and I'd like to show this in an interaction plot: interaction.plot(group, city, pressure, type="b", col= c(1:2), leg.bty="o", leg.bg="blue", lwd=1,

I would guess that in a CI system the order doesn't matter much because you look at a webpage? I looked at some build bots today/yesterday that now also show this, and yeah, it's fine either way, I was guessing. My primary use-case is usage in a terminal, and displaying the errors first followed by all input makes this pretty unusable. ________________________________ From: Chris

I sent a post to find a clever way to compute a Rolling Average of columns in a matrix and I was given the solution below which I am very pleased with. RollingAverage <- function(x, RollingObs) { cx <- cumsum(x); N <- length(x); Temp <- (cx[RollingObs:N] - c(0, cx[1:(N-RollingObs)]))/RollingObs Output <- array(NA, N) Output[RollingObs:N] <- Temp; Output } The only

Hi, I am having a problem in doing something similar to this example: Suppose I have this vector a, and from it I wish to create 5 other vector each one with less one value than what object a has So I have "a" a<-c(1,2,3,4,5) and I want a1 that shoud have (2,3,4,5) a2 that should have (1,3,4,5) a3 that should have (1,2,4,5) a4 that should have (1,2,3,5) a5 that should have

Hi People! I have following concern consisting of some steps to do in R: I have an ascii file (table) consisting of many columns and rows. 1. I would like to order all values of the columns one under each other. It will begin with column 1, then column 2 under column 1, column 3 under column 2 etc. until at the end there is only 1 column. How do I do it? 2. Second problem is to make a

G''day I''ve been performing an analysis of some data by a follow the leader method (Bad I know but it seems to work and I think I understand all the steps now) and I''ve run into a problem. The analysis is for all practical purposes identical to the non-linear mixed effects analysis performed on Ludbrooks Rabbit data in the second edition of Venables & Ripley (page

As for the ordering issue... from the command line, I tend to set verbosity high, and so I pipe to a pager and search for "error:". I prefer errors before the input dump then. My point is that it should be configurable if we change the default ordering. Joel On Thu, Jun 18, 2020 at 1:13 PM Joel E. Denny <jdenny.ornl at gmail.com> wrote: > Thanks for bringing this discussion
