similar to: dataframe package

Hi everyone! In a package I'm developing, I have created a custom function to get jackknife standard errors for the parameters of a gnm model (which is essentially the same as a glm model for this issue). I'd like to add support for bootstrap using package boot, but I couldn't find how to proceed. The problem is, my data is a table object. Thus, I don't have one individual per

I did some benchmarking of data frame code, and it appears that R 3.0.0 is far worse than earlier versions of R in terms of how many large objects it allocates space for, for data frame operations - creation, subscripting, subscript replacement. For a data frame with n rows, it makes either 2 or 4 extra copies of all of: 8n bytes (e.g. double precision) 24n bytes 32n bytes

I'm trying: R CMD Rdconv file.Rd --type=Ssgm If file.Rd contains \code{x} then this is currently translated as <s-expression>x</s-expression> I suggest instead translating to <code>x</code> (provided that R CMD Sd2Rd is changed to support the <code> tag; I just submitted that bug separately). Note that this is an enhancement, not a bug. This change would

Tim, I have reported some similar issues a while back and there was some discussion on this topic: http://tolstoy.newcastle.edu.au/R/devel/06/03/4609.html Good luck, Kevin On Tue, Jun 10, 2008 at 6:47 PM, Tim Hesterberg <timhesterberg at gmail.com> wrote: > Here are three different scenarios in which the browser() exits > when I don't want it to.

Hi, I read section 5, oop, of the R lang doc, and I am still not sure I understand how to build a class in R for oop. I thought that since I understand the oop syntex of Java and VB, I am wondering if the R programmig experts could help me out by comparing and contrasting the oop syntex in R with that of Java. For example, the basic class structure in Java is like this: public class Bicycle {

I would like to use the output from the map function in the package maps for use in, say, the spatstat package. I don't quite understand the coordinates for the border of the state: Example: library(maps) iowa<-map("region","iowa) x<-iowa$x y<-iowa$y There are NA's and duplicated coordinates. What would I need to do to use this in the spatstat owin command?

Nick, First, thanks for responding. Secondly, I just want to create an exact copy of an already exisitng Value, this should be pretty simple to do but I'm unclear on how to do this? For example, PHINode::getIncomingValue (unsigned) returns a "Value" and I want to make a copy of that Value. Is there some other way to do this other than copyValue() that I'm missing? On Sat,

I''m having trouble getting a simple custom type to work. Clients are giving me the following error: "Could not retrieve catalog: Could not find resource type zypper_repo at /etc/puppet/manifests/nodes/mgt.pp:33 on node <host.fqdn>" The custom type is present in the /var/lib/puppet/lib/puppet/type directory on both clients and server (via pluginsync), but it''s

Since there are no constructors for Value, how do you properly insert a new Value? If I create a pointer Value *newValue and then call AA.copyValue(oldValue, newValue), this does not work, since newValue is not allocated. -------------- next part -------------- An HTML attachment was scrubbed...

Hola a tod en s, explico lo que estoy intentando hacer... Tengo un listado de url comprimidas de twitter, entre las cuales hay muchas repetidas, por lo que el número de registros llega a más de 15K. Por otro lado tengo otra lista de esas url únicas con su equivalente ya descomprimido llegando a un registro de 900. El problema que tengo es que estoy intentando hacer un loop para hacer la

Hi, I am trying to allow certain nodes to override variables in inherited classes. Here''s an example: node ''my.server.com'' inherits webserver {} node ''other.server.com'' inherits webserver { $var = "newvalue" } node webserver { $var = "value" include snmp, dns, classx } In this example classx ends up using

Ah, I think I get it now. This was mentioned earlier in the thread, but it didn't click at the time. It sounds like I can do instruction selection with a pattern like (omitting selection of the sources): let Constraints = "$dst = $oldvalue" in { def MASKEDARITH : MyInstruction< (outs VectorReg:$dst), (ins MaskReg:$mask, VectorReg:$src1, VectorReg:$src2,

Hi, consider this one as an FYI, or a seed for further discussion. I am aware that many traps on sample() have been reported over the years. I know that these are also documents in help("sample"). Still I got bitten by this while writing sample(units, size=length(units)); where 'units' is an index (positive integer) vector. It works in all cases as expected (=I expect)

Insightful are pleased to announce we are now taking bookings for our latest course on "Bootstrap methods and permutation tests" in the UK on 23rd - 24th October. This course will focus in particular on two resampling methods, bootstrapping and permutation tests, which have been applied successfully to areas of statistical modelling where "traditional" standard errors,
