similar to: aggregate() example fails

Hi R users and developers on debian platforms. I compile the R version 2.8.1 Patched (2009-03-18 r48193) on my UBUNTU linux distribution. But when I ask for the aggregate example it fails. What am I missing? example(aggregate) aggrgt> ## Compute the averages for the variables in 'state.x77',grouped aggrgt> ## according to the region (Northeast, South, North Central,West) that

Hi R developers and debian users: Finally I found how to work with aggregate() function on the last patched version fo R. I you use this command it fails: aggregate(state.x77, list(Region = state.region), mean) But if you modify it in this way, it works!: aggregate(state.x77, list(Region = state.region), function(x) mean(x) ) Is it necesary to change the example? What is changing in

Dear all, I want to aggregate() my data based of the classes of a factors, just as in the help file, but how do I define the "Region varable" in the ?aggregate example? Now, the column is just like any other in my data matrix. As I understand it from ?(state), state contains a matrix with the columns Pop, Income etc., but Region is somehow separated. I noted below that as.list() is

I tried: > data(state.x77) Warning message: In data(state.x77) : data set 'state.x77' not found data(iris) seems to work fine, but the other state datasets (which I haven’t every tried before) don’t seem to be available on my windows 7 running R 2.12.2 installation. ?state brings up the state help page page which suggest the dataset should still be there. In help there still seems to

I try to display the grouping variable in coplot. It work, but it's special solution and rather ugly. Any better idea? # Simulate my data frame data(state) x77<-data.frame(state.x77) x77$region<-state.region coplot(Life.Exp ~ Income | region, data=x77, show.given=F, subscripts=T, panel = function(x, y,subscripts, ...) { panel.smooth(x, y, span = 1., ...)

I just made a DFS link that pointed to another DFS share on a different server... It seems to confuse the Win'XP client a bit, but it can be made to work. That means.... I can build a tree structure w/ DFS. I can arrange all my servers and shares into a hierarchy. It may not be practical, but in theory, This could be used as a hierarchical substitute for the network neighborhood. I could

Hello, this is a request for assistance that I submitted earlier, this time with the dataset. My mistake for taking up bandwidth. I've also rephrased the question to address an additional concern. I'm working on a windows XP machine with R 2.8.1 1). I'd like a barchart (or other lattice type display) HSI ~ of the three factors (Region, Scenario and HydroState). However

This code opens a CSV file from the working directory set by wd. I copy 2 or more columns in the spreadsheet and then close it. What I need help with is setting the first row as the column names in clipboardTextAsDF. There is probably a simple or better way to do this but I have been away from R for awhile now. I just be over-thinking this. I tried read.DIF to read the clipboard but that

Is there a working Rails-based CMS out there and available? I''ve looked on the web a bit this morning but have not found anything that can be put in use. Thanks!

I''m trying to select items from a database by their date field. The date data is coming from a form using the date_select helper. The field in the database is named date_notified_on. My controller method is this: def history_date if(@params) @notifications = Notification.find(:all, :conditions => ["date_notified_on = ?",

R 1.4.0 ?stars has scale: logical flag: if `TRUE', the columns of the data matrix are scaled independently so that the maximum value in each column is 1 and the minimum is 0. If `FALSE', the presumption is that the data have been scaled by some other algorithm to the range [0,1]. but the code has if (scale) { x <- sweep(x, 2,

Hi all, I am trying to make tiff files of lattice plots at a resolution greater than 300 dpi required by a journal (PLoS ONE). I have tried both the tiff and bitmap functions. tiff keeps panel colors but reduces axes and tick labels so they are nearly invisible. bitmap maintains correct label size but only produces greyscale. Regular plots work fine with tiff; the problem is only with lattice

If an email incoming to Actionmailer has an .htm attachment, how is it possible to extract the file''s text (the html text in the file) to insert into the database? I''ve tried reading the attachment like so, theFile = File.open(attachment.read, "r"), to no avail. But that fails stating that there is no such file or directory (but the attachment is there for certain).

In case where a collection_select is selecting a required value for an object (a not null field), is it possible to set a generic default value for the select box? I have tried :prompt => true and :include_blank => true but neither changes the value for required fields. It does for non-required fields though. Thanks.
