Hello! I have dates for the beginning of each week, e.g.: weekly<-data.frame(week=seq(as.Date("2010-04-01"), as.Date("2011-12-26"),by="week")) week # each week starts on a Monday I also have a vector of dates I am interested in, e.g.: july4<-as.Date(c("2010-07-04","2011-07-04")) I would like to flag the weeks in my weekly$week that

Hi, I am trying to generate all unordered combinations of a set of numbers / characters, and I can only find a (very) clumsy way of doing this using expand.grid. For example, all unordered combinations of the numbers 0, 1, 2 are: 0, 0, 0 0, 0, 1 0, 0, 2 0, 1, 1 0, 1, 2 0, 2, 2 1, 1, 1 1, 1, 2 1, 2, 2 2, 2, 2 (I have not included, for example, 1, 0, 0, since it is equivalent to 0, 0, 1). I have

Hello All, I have a list of dataframes, and I need to subset it by keeping only those dataframes in the list that meet a certain criterion. Specifically, I need to generate a second list which only includes those dataframes whose number of rows is > 1. Could someone suggest how to do this? I have come close to what I need with loops and such, but there must be a less clumsy way... Many

I'm still getting used to R's scoping. I've run into the following situation value=0 thefunction <- function() print( value ) somefunction <- function() { value=99; thefunction() } somefunction() now, I understand that somefunction() returns 0 because thefunction() was defined with value=0 in its parent envrionment, it dosent look at all in the environment of somefunction. My

Hello all, I need to extract rows and columns from a data frame and put them in a matrix. In some cases, there are no rows in the data frame meeting the selection criteria. For those rows I want to put a row of 0's in the matrix. Here's my clumsy code: tab1.m1 <- matrix(0, nrow=2, ncol=4) tab1.m1[1,] <- ifelse(length(as.matrix(tab1[tab1$comp==the.comp & tab1$schlid==the.schl

I have a web application that is getting larger all the time. There are now 3 separate models where I am storing the current find parameters in session hash and it''s beginning to seem to me that this might not be a good idea. Before I add another model to the mess - is there a better way? Do I have to create some table to store the current ''find'' criteria? It seems as

Dear all, I'm looking for a function comparable to switch, to categorize a continuous variable in a few levels. Off course that can be done with a series of ifelse statements, but that looks rather clumsy. I looked at switch, but couldn't figure out how to use it for this. I guess that's not possible, as it only works with characters or integers, not with intervals. Basically,

Hi, I am new to R and need to read in a file with 19 columns and 7000 rows and make it into a list of 7000 lists with 19 items each. For a simpler case of 10 by 10 table I used x <-scan("file", list(0,0,0,0,0,0,0,0,0,0)), perhaps clumsy, but it did the job. However with the large 19x7000 (which needs to be transposed) I am not sure how to go about it. Coudl somebody suggest a way?

Is it possible to generate graphical output (to a file) when the DISPLAY environment variable is not set? Here's the problem: $ unset DISPLAY $ R > png("foo.png") Error in X11(paste("png::", filename, sep = ""), width, height, pointsize, : unable to start device PNG In addition: Warning message: unable to open connection to X11

I am running R as an invisible subprocess in another program (RExcel). Using try I can catch errors and print the errors produced by an R statement. Is there a way to know if running a statement caused a warning message? last.warning gives me the last warning, but I do not have any indication what the statement was that caused the message. I can of course store last warning before I run a

Suppose I have a plot plot(1:10, pch = "") And I want some text to indicate a Normal distrubition. I could do this: text(5, 6, substitute(X~~~~N(mu, sigma^2)), adj = 0) text(5.35, 6, "~", adj = 0) But that's clumsy, and depending on your plotting device, might not even look sensible. I'd prefer to be able to do it more directly and simply the way these do: text(5,

I would like to create a certain number of dataframes out of one dataframe where each of the dataframes is related to a factor. This should be possible with a loop or a function, as is very clumsy to do it manually when there are quite a lot factors. For example having a dataframe called "exmpl": Site Value 1 12 1 15 1 18 1 21 1 12 1 13 2 15 2 12 2 58 2 62 2 22 2 65 2 29 3 21 3 55

I'm writing a load of output to a file using cat(...), but I can't work out how to turn off scientific notation for small numbers. When I originally tried this a while a go I ended up building up a string variable, which is rather clumsy...

Greetings All. The function edit.data() allows a convenient spreadsheet-like view of a dataframe with too many rows/columns to fit on the screen (especially when there are many columns). Very useful when scanning through a dataset (row & column are conveniently identified by the labels at the side and above). However, there seens to be no option to set it "read-only" on start-up,

I large datset that includes subjects(ID), Dates and events that need to be counted.  Not every date includes an event, and I need to only count one event per 30days, per subject.  So in essence, I need to create a 30-day "black out" period during which time an event cannot be "counted" for each subject.  The reason is that a rule has been set up, whereby a subject can only be

Hi there, I am using an old (really old) APC Smart-UPS 600. It worked fine under apcupsd but when I tried NUT it did not work. The error I was getting was: sudo /lib/nut/apcsmart -DDD /dev/ttyS1 Network UPS Tools (version 2.0.4) - APC Smart protocol driver Driver version 1.99.8, command table version 2.0 debug level is '3' Attempting firmware lookup Firmware: [D4] Not found in

Hi there, I have data frame with columns ID and Date. There are multiple rows for each ID, but I only want to keep the *first* such row--i.e., the row corresponding to the earliest event. So if I had, say, 1000 rows of 100 IDs doing an average of ten events each, I'd run this trimming procedure and end up with a data frame containing 100 rows (one for each ID), where each row record that

Hello, All: What facilities exist for plots and tables of data in the standard MediaWiki software beyond the obvious standards? The standard MediaWiki tables and graphics capabilities seem to me to be rather clumsy, and I wonder if I'm missing some available extensions? The standard MediaWiki tables are described in a Wikipedia article on "Help:Table".

Trying to use R to build an interactive "slide show", to be displayed on a projector. The purpose of the presentation is to show how one could construct a simple graph using R. It is meant as a general overview rather than as detailed instruction. For example, something like the following sequence of commands. At lecture time, I want the interpreter to read these commands one at a
