II just want to create a new object with the first two numerals of the data. Not sure why this isnt working, consider the following: EmpEst$naics=c(238321, 624410, 484121 ,238911, 811111, 531110, 621399, 541613, 524210 ,236115 ,811121 ,236115 ,236115 ,621610 ,814110 ,812320) EmpEst$naics2<-formatC(EmpEst$naics %% 1e2, width=2, flag="", mode ="integer") #RESULT:Warning

Hi R fans, As a newbie following the five-hour rule (after hitting my head against the wall for five hours, post to this list), I am appealing for some help understanding geom_rect() in ggplot2. What I want to do is very simple. I want to generate a plot of rectangles. Each one represents a business cycle. The x-values will be pairs representing the start and end of each cycle. The y-values

I am working on creating an R package for doing fire department analysis and am trying to create a function that can display emergency incident densities. The following code sort of does the trick, but I need a display that shows the number of incidents per square mile. I believe the code below shows incidents per square unit (in this case, degrees lat/long). To solve this problem, I believe

Hi, I am trying to read a tab-delimited file that has trailing tab delimiters. It's a simple file with two legitimate fields. I'm using the first as row.names, and the second should be the only column in the resulting data frame. Initially, R was filling the last column with NA's, but I was able to stop that by setting

Dear users, I have monthly station data (44) stations data for 45 years which I have read in R using read.table. the data is in the format: Year Month Station1 Station2 ...................................... Station 44 (i.e the column names in the 1st row), I also have the latitude and longitude of the stations in a separate file in R (in the format : Station LAT LON). I wish to

I'm surprised this isn't a FAQ, but I searched all over and could not find a reference to it. Chambers (1998) makes repeated references to "Chapters" in S (e.g., p. 6), but I can find no reference to "Chapters" in R. Since Chapters were not used in earlier versions of S, I'm wondering if R uses them or not. If it does, how does one get them to work? I've

Hi, I have a bright, diligent second-year graduate student who wants to learn statistics and R and will, in effect, be taking a tutorial from me on these subjects. (If you've seen some of my questions on this list, please don't laugh.) As an undergrad he majored in philosophy, so this will be his first foray into computer programming and statistics. I'm thinking of having him use

Hello, I have a function with these lines: test <- function(object,...){ cat("object: has ",nrow(object),"labels\n") cat("Head:\n") head(object,...) cat("\nTail:\n") tail(object,...) } If I feed it a data frame object, it only prints out the tail part. If I comment out the last two lines of

Hi, I have two further comments/questions about large datasets in R. 1. Does R's ability to handle large datasets depend on the operating system's use of virtual memory? In theory, at least, VM should make the difference between installed RAM and virtual memory on a hard drive primarily a determinant of how fast R will calculate rather than whether or not it can do the calculations.

Hi, I can't get the colClasses option to work in the readHTMLTable function of the XML package. Here's a code fragment: require("XML") doc <- "http://www.nber.org/cycles/cyclesmain.html" table <- getNodeSet(htmlParse(doc),"//table") [[2]] # The main table is the second one because it's embedded in the page table. xt

Hi, I've been struggling with this problem the last few days and finally discovered it's happening at a very fundamental level. Going through Stephen Turner's tutorial on ggplot2, I entered these base graphics commands: > with(diamonds, plot(carat,price)) > with(diamonds, plot(carat,price), xlab="Weight in Carats", ylab="Price in USD",

Hello R wizards, What is the best way to read a data file containing both fixed-width and tab-delimited files? (More detail follows.) _*Details:*_ The U.S. Bureau of Labor Statistics provides local area unemployment statistics at ftp://ftp.bls.gov/pub/time.series/la/, and the data are documented in the file la.txt <ftp://ftp.bls.gov/pub/time.series/la/la.txt>. Each data file has five

I'm trying to read two data sets in json format from a single .js file. I've tried fromJSON() in both RJSONIOIO and RJSON packages, but they require that the lines be pre-parsed somehow in ways I don't understand. Can someone help? > wheat <- readLines("http://mbostock.github.com/protovis/ex/wheat.js") > str(wheat) chr [1:70] "var wheat = [" "

Hello All, Does anyone know how to download historical LIBOR rates of different currencies into R? Or if anyone knows of a website that holds all this data...I only need up to january of 2000. Also, how can we make the row names the index of a plot (the names of the x values)? [[alternative HTML version deleted]]

Hi R-helpers, My real data is a panel (unbalanced and with gaps in years) of thousands of firms, by year and industry, and with financial information (variables X, Y, Z, for example), the number of firms by year and industry is not always equal, the number of years by industry is not always equal. #reproducible example firm1<-sort(rep(1:10,5),decreasing=F) year1<-rep(2000:2004,10)

I R-helpers #I have a data panel of thousands of firms, by year and industry and #one dummy variable that separates the firms in two categories: 1 if the firm have an auditor; 0 if not #and another variable the represents the firm dimension (total assets in thousand of euros) #I need to create two separated samples with the same number os firms where #one firm in the first have a corresponding

Suppose we observe N individuals, for each of which we have a time-series. How do we correctly create a lagged value of the time-series variable? As an example, suppose I create: A <- data.frame(year=rep(c(1980:1984),3), person= factor(sort(rep(1:3,5))), wage=c(rnorm(15))) > A year person wage 1 1980 1 0.17923212 2 1981

Hello, I've been very impressed by the reshape package and how easy it makes reorganizing statistical data structures. This makes me wonder if there's another package out there that addresses another set of tasks that one often does when preparing data for analysis. For any particular set of analyses, one typically recodes variables and deletes cases and variables. It would be really
