Hi, I am trying to aggregate the sum of my test data.frame as follow: testDF <- data.frame(v1 = c("a", "a", "a", "a", "a", "b", "b", "b", "b", "b", "c", "c", "c", "c", "c", "d", "d", "d", "d",

Dear R users, Suppose I have the following data.frame: myID myType myNum1 myNum2 myNum3 a Single 10 11 12 b Single 15 25 35 c Double 22 33 44 d Double 4 6 8 and I want to have new records: myID myType myNum1 myNum2 myNum3 e Single 12.5 18

hello, i am trying to extract text using regex as follows: "* < <* this is my text > > " into: "this is my text" below what I did: varReg <- "* < <* this is my text > > " ## either this pattern patReg <- "(^[ <*]+)" ## or below patten patReg <- "([ > ]+$)" sub(patReg, '', varReg) depending

Hi, I have newbie question. Suppose I have the following data: temp <- data.frame(type1 = c("male", "female", "male", "female", "female"), type2 = c("low", "med", "high", "low", "med"), a = c(1,2,4, NA, 3), b = .... [TRUNCATED] temp type1 type2 a b c 1 male low 1 5 0 2 female

Dear R-Users, Suppose I have data in the following format: CODE_NAME ZIP_CODE John 12345 John 23456 John 34567 Jane 13242 Jane 22123 I want to transpose / convert it into: CODE_NAME ZIP_CODE John 12345,23456,34567 Jane 13242,22123 Any idea/pointer is appreciated.

Dear R users, I have the following data: x <- data.frame( myX = c(1,2,3,4,5,6,7,8,9) ) y <- data.frame( myX = c(1,2,3,4,5,6,7) ) How can I get the difference between data frame x and y? In this case, I want to get values 8 and 9 I know in SQL we can use minus operator, but I have no idea how to do so in R. I tried all.equal, diff, and identical, but they don't give me the actual data

Dear R users, How to change lattice panel label/text from the automatically generated label (based on the conditioning) to our own set of label? for example: someStuff <- data.frame(area = rep(c("SOUTH", "NORTH", "EAST", "WEST"), each = 25), group = rep(c("A","B","C","D"), each = 5),

Hi, I am trying to display / print certain columns in my data frame that share certain condition (for example, part of the column name). I am using for loop, as follow: # below is the sample data structure all.data <- data.frame( NUM_A = 1:5, NAME_A = c("Andy", "Andrew", "Angus", "Alex", "Argo"), NUM_B = 1:5, NAME_B =

Hi, I have the following type of data: myData <- data.frame(x = 1:5, y = letters[1:5], xDate = seq(as.Date("2001/2/1"), as.Date("2005/2/1"), by="year") ) > myData x y xDate 1 a 2001-02-01 2 b 2002-02-01 3 c 2003-02-01 4 d 2004-02-01 5 e 2005-02-01 What I need is a new column, say xDate2, that for each xDate (or for each unique combination of

Dear R users, Is it possible to have an overlap histogram plot? For example: stuff <- data.frame(Mode = c("Land", "Air"), AgeGroup = c("Young", "Adult", "Old"), Value = sample(1:300)) histogram( ~Value | AgeGroup * Mode, data = stuff, auto.key = TRUE) Instead of having 2 * 3 panel, I want to have just 3 panel, overlapping the "Mode"

Hi all, I 've just reinstalled from the scratch my Windows 2000 (Italian version) on a formatted HD, because I like to clean the environment from time to time (say once a year). I'm currently using XEmacs-21.4.13 and R (rw1091) and Xemacs is configured as described in http://socserv.socsci.mcmaster.ca/jfox/Books/Companion/ESS/ess-xemacs.pdf The problem is that the command help.start()

Hi, I am trying to find a way to automate production of page numbers in plots produced using the lattice package. To do this, I started playing around with setHook which works fine with vanilla plot, but the hook 'plot.new' doesn't appear to be relevant to the lattice package. I was wondering if there is a alternative someone can suggest for use with the lattice package. Example

Hello list, I have two vectors x and x2: x=runif(10) x2=runif(10) and one vectors with their names : my.names=c("x","x2") I would like to cbind these two vectors using their names contained in the vector my.names. I can create a string with comma ncomma=paste(my.names,collapse=",") and now, I just need a function to transform this string into a adequate

Hi, is there away to assure that a package is detached when R quits? I know about .Last(), but that requires the user to setup that function. What I am looking for is a way for the package to do this itself, without asking the user to edit "their" .Last(). From ?setHook I know that: "...when an R is finished, packages are not detached and namespaces are not unloaded, so

I keep getting repeated copies of ``R-help post acknowledgements'' in respect of a couple of postings that I made to the list this morning (my time). I only posted each posting *once*. I hope that others are not getting repeated copies of my postings .... I mean I *know* my postings are so wonderful they merit re-reading, but one does not need another copy in order to re-read! :-)

I would like to get some idea of which R-packages are popular, and what R is used for in general. Are there any statistics available on which R packages are downloaded often, or is there something like a package-survey? Something similar to http://popcon.debian.org/ maybe? Any tips are welcome! ----- Jeroen Ooms * Dept. of Methodology and Statistics * Utrecht University Visit

Hey y''all, Are any folks planning on taking the ferry from Seattle to Vancouver (via Victoria)? I''ve never done it before so I have no idea how much of an adventure it is. Flights are a $100+ less to Seattle than Vancouver so the price works out the same or a bit less. My plan is to fly to Seattle (from Savannah, GA) on Tuesday to catch the early ferry on Wednesday

Hi all, several packages print messages during loading. How do I avoid to see them when the packages are in the defaultPackages? Here is an example. With this in ~/.Rprofile ,----[ ~/.Rprofile ] | old <- getOption("defaultPackages") | options(defaultPackages = c(old, "filehash")) | rm(old) `---- I get as last line when starting R: ,---- | filehash: Simple key-value

Hi, i am using spatstat package for spatial data analysis and now i have a problem to create a point pattern. The points are in file "points.txt" (first column for Latitude and second column for Longitude ) and I imported them and separated each columns in two arrays x and y. If I plots x and y ( e.g plot(x,y) ) the result appears in square area without problems and the scale is

Dear all, I want to simulate a Strauss Hard Core process in 3D. I have found that someone else tried to do the same and he recived this answer, "If you need this immediately, I suggest you follow Brian Ripley's advice. This probably involves downloading a source tar file of the R package and finding the Fortran code in library/spatial/src/. The Fortran should be edited to generate 3D
