similar to: unixtime conversion

I'm new at R ... I've not done for loops in R - so this is very new to me. One of our students has a data frame that contains two columns data 1. unixtime time of an event (in unix time - #of seconds) 2. duration of event in seconds. We need to create new data - the unixtime (seconds) that these events occurred. We want to create a for loop (or nested for loops) that goes through the

Hi! I'm new to R, and I have a question about how R works with large data sets --- in particular, data sets that come from databases. I'm using R 2.2.0 with the DBI package (0.1-9) and the RMySQL package (0.5-5). My get-my-feet-wet-with-R project is to make a histogram from a data set stored in a MySQL database. In particular, I have a table that describes some observed spam emails.

Hi, is there a grayscale setting for lattice plots? I like the default color settings. I also like the settings that are available for setting black and white with something like this: --8<---------------cut here---------------start------------->8--- ltheme <- canonical.theme(color = FALSE) ## in-built B&W theme ltheme$strip.background$col <- "transparent" ##

Hi, I would like to add confidence intervales to an ANCOVA with 2 covariates when using xyplot. What would be a good way of accomplishing this? --8<---------------cut here---------------start------------->8--- rm(list = ls(all = TRUE)) rm(list = c(ls())) library(lattice) ## 1. generate data random <- rnorm(200) y <- abs(random) x1.cont <- abs(random) x2.fac <-

Hi, what is the recommended way of adding a strip to a lattice plot? In the example below I would like to add the value of mean(y) to a new strip.: --8<---------------cut here---------------start------------->8--- library(lattice) ## Small sample data set: p0 <- xyplot(uptake ~ Type | Treatment, data = CO2) p1 <- update(p0, panel = function(x, y, ...) {

Hi, I was wondering if there is a ready made function or parameter for indicating the sample size in boxplots? Here's what I came up with so far: library(ISwR) data(energy) attach(energy) boxplot(expend~stature) sample.size <- tapply(expend, stature, length) sample.size <- paste("N=", sample.size, sep="") mtext(sample.size, at=1:length(unique(stature)), line=2,

In a quest to remove ?duplicate? messages sent to both me and lists I subscribe to I came up with this, which I think should clean out my Archive folder, but I?ve been unable to get it to work for scanning all on my list-user email. $ doveadm -f table fetch -u kremels 'hdr.message-id guid uid hdr.x-listname' mailbox "Archive" | sort| awk 'cnt[$1]++{if (cnt[$1]==2) print

Hi, I was wondering if it's possible to have fonts in plots to be autoscaled to the same font size used by LaTeX in a surrounding Sweave document. Here's a short example in which the fonts of the first plot are barely readable: --8<------------------------schnipp------------------------->8--- \documentclass{article} \usepackage{graphicx} \newcommand{\mytext}{Some normal sized

Hello, I'm trying to get last login user tracking going, using Dovecot and mysql. I'm using: https://docs.iredmail.org/track.user.last.login.html and it is working, I am seeing an entry and it is updated, the problem is the last login value does not mean anything to me. I was wondering if it's possible to have the value be of a last login date and time, and also a remote ip would be

Hi, what would be a good way of enhancing the ancova function from the HH package when using a 2 factor ANCOVA? The current behaviour for the "ancova" function from package HH is: ---------------------------------------------- | P1 || P1 || P3 || P4 | | PS | <- the lattice strip ---------------------------------------------- | x|| x ||x ||x | |

Hi, I am performing a two-way ANOVA (2 factors with 4 and 5 levels, respectively).
