[Environment: WinXp, R 2.9.2, all packages up to date; building under (StatET 0.8, eclipse 3.5.1) or from a batch file] I'm in the process of creating a package, HistData, on R-forge, containing interesting data sets from the history of statistics and data visualization. It contains several examples that use ggplot2, which I've declared as a Suggests: in the DESCRIPTION file. The examples work fine when run in a separate R session. However, they fail under...

Hi, I am facing the problem that I want to plot a histogram chart set freq to true and overlay with normal or weibull or exponential distribution curve. The sample code is shown as below: >samp<-c(-8.2262,-8.2262,-8.2262,-8.20209,-8.09294,-8.07321,-8.07321, -8.07321,-8.07175,-8.04948,-8.04948,-8.04948,-8.03848,-8.03848,

In the HistData package, I have a data frame, PearsonLee, containing observations on heights of parent and child, in weighted form: library(HistData) > str(PearsonLee) 'data.frame': 746 obs. of 6 variables: $ child : num 59.5 59.5 59.5 60.5 60.5 61.5 61.5 61.5 61.5 61.5 ... $ parent : n...

I am looking for a function (or package) to plot histograms of directional data such as wind direction. I believe these are called rose diagrams. Is there an R script for this? If not, can it be constructed in a function calling primitive graphic calls (lines, circles, boxes or polygons)? The stars function is not quite right. -- David Finlayson Geomorphogist and GIS Specialist NearPRISM -

Using R 2.13.1, I am now getting the following NOTE when I run R CMD check on my HistData package * checking for unstated dependencies in examples ... NOTE 'library' or 'require' calls not declared from: gplots sp Under R 2.12.x, I didn't get these notes. I have ~ 25 .Rd files in this package, and AFAICS, every example uses library or require for the functions...

Dear R Folks, I know that Enrique Bengoechea ( Credit Suisse ) had posted some code snippets for importing Bloomberg historical data into R. I found them to be very useful. Has anyone succeeded in getting the below items from Bloomberg to R? (a) historical economic release data, (b) tick/intra-day data (c) bulk data such as Index membership info, etc. If someone is willing to share their code

Hi RUsers, Suppose I want to see the data on the website url <- "http://www.nseindia.com/content/indices/ind_histvalues.htm" for the index "S&P CNX NIFTY" for dates "FromDate"="01-11-2010","ToDate"="02-11-2010" then read the html table from the page using readHTMLtable() I am using this code webpage <-

Hello dear R users, *Here is the background for my question:* I just had a look at the help file for ? Yeast in the "HistData" package. In it, I found a small spelling mistake where the word "*c*istribution" was written instead (so I imagin) "*d*istribution". I thought maybe I should e-mail the developer. Since there is no link to contacting the developer inside that help page, I went and googled...

With good and faithful python remote database queries look something like this: url.urlopen("username/pssword at host",query) where query is something like "select * from table where ...." Does R support queries on remote hosts with username and password? What does a simple example look like? Thank you.
