Dear users, 1. Is there a way to create a movie file to play a sequence of single frames (e.g. plots) at a specified time delay between frames? 2. If making a movie file is not possible, then how can I incorporate in a loop some delay between the frames to be plotted so I can change the playing speed? Sorry if this questions was already in the forum, but I couldn?t find it. Thanks in advance

Anybody have an idea why I would get a non-integer value for the number of days here? > difftime('2004-08-05','2001-01-03',units='days') Time difference of 1309.958 days Would you just round off? Best, Jon

Dear All, I am wondering is there any shift (or pop or push or unshift) equivalent in R? For example, shift(x) # should return x[1], and x becomes x[-1] Thanks a lot. Best Regards, Xie Chao

Hello R users, I would like to generate "slanted" stacked bar graphs like those on the bottom of pages 1 and 2 in this document: http://www.wssinfo.org/fileadmin/user_upload/resources/JMP-Snapshot-SWA-HLM.pdf . I've also attached the file to this email (pdf). Does anyone know if this is possible in R? I have tried googling and searching the R help archives, and it seems like ggplot2

R Developers, I cannot seem to find an R package that can read/write iCalendar (RFC2445) files. I have found the libical library at sourceforge. I've used it briefly so it may be what I need, but again no R interface. I may have to connect the dots myself. I'm guessing this might be useful for someone other than myself (scrubbing files, performing temporal analysis on events, etc).

Hello, I would like to organize the "R" directory in my home-grown package into sub-directories, but "R CMD --build" doesn't seem to find *.R files below the actual source directory. Is there any way around that? Thanks, Joh

Hi, I found in a bit of code the following test for infinity: if (x == Inf) ... Is that valid, or should it be (as I always thought): if (is.infinite(x)) ...? Does it depend on whether 'x' is float or integer? My question is related to testing for missing values where is.na(x) is required. /Henrik

Hi, I am working with a SpatialPolygonsDataFrame of many islands. There are a lot of polygons (islands) composing my SpatialPolygonsDataFrame. I want to extract the elevation of each island. I need to separate the different polygons (like dissolve function in arcgis), to have the elevation of each island. Do you have any idea how can I do that ? I already read a lot of forum, and read the

Dear R helpers   I have written some function (the actual code I have pasted at the end of mail) like say   indiv_rate = function(n, rate_name, rate, rate_rf1, rate_rf2, rate_rf3, rateprob1, rateprob2, rateprob3) { ........some R commands   return(data.frame(rate_name, rates = round(rate_data, digits = 4)))   }   ## INPUT   rates = indiv_rate(n = read.csv('number.csv')$n, rate_name =

I have a pdf file that I would like to parse into R: http://www.williams.edu/Registrar/geninfo/faculty.pdf For now, I open the file in Acrobat by hand, then save it "as text" and then use readLines(). That works fine but a) I am concerned that some information may be lost and b) I may be doing this a lot, so I would rather have R grab the information from the pdf file directly. So: is

Dear all, I have received the following error message since R 2.10.1 for the first time and I am not able to draw graphics any more: > plot(1:5,1:5) > plot(1:5,1:5) Error in plot.new() : figure margins too large In addition: Warning message: Display list redraw incomplete > sessionInfo() R version 2.10.1 (2009-12-14) i486-pc-linux-gnu locale: [1] LC_CTYPE=en_US.UTF-8

Dear all, I would like to make a large scatter plot created with R available as an interactive web graphic, in combination with additional text-annotations for each data point in the plot. The idea is to present the text-annotations in an HTML-table and inter-link the data points in the plot with their corresponding entries in the table, i.e. when clicking on a data point in the plot, the

Hi all, I am trying to do something simple, but which is deviling me. I want to add an up-arrow to the x-axis, pointing to a specific location on the axis. I want the arrow to be as large as possible. Here is where I'm at with my code: #this part if from the ?plot example: require(stats) plot(cars) lines(lowess(cars)) #I am trying to use mtext to add the arrow... but I don't know how

Hi the list, I use rgl to produce a 3D graph. I would like to "show" this graph to some collaborator. Is there a way to save it and send it to someone else? Christophe Genolini

Is CRAN having trouble or is it just me? (The web interface is very slow and install.packages() is timing out and giving me "service not available").

Hi I've recently been trying to solve some probability questions in R, but am having trouble. This is one question thats been causing some hair loss: Given the set of integers S = {1,2,3,4,5,6,7,8,9,10}, create a function F(S) that uniformly and randomly rearranges these integers. For example, in one instance, we might have F(S) = {2,3,9,7,5,6,1,8,10,4}.
