Hi all, I have been trying to run a bestglm in R for a while now and am struggling to get it to run. When I thought I had succeeded, the "output" it gave me was "NULL" and that's it. Below is my code: bestglmtest<-read.table("C:\\Documents and Settings\\clyons\\Desktop\\bestglmtest.txt",header=T,row.names=1) > names(bestglmtest) [1] "acc"

Dear useRs: Is there a way to include a raster image (e.g., .gif, .jpg, .bmp) representing a company logo, a school logo, etc. into an R graphic? For example, it would be nice to be able to include the logo of the school into the charts that a student produces for her dissertation. Similarly, while working on a competitive analysis, it would be nice to be able to replace the names of the

It seems that Access needs that you surround the dates with a # symbol. You probably need something like. res <- sqlQuery(channel, "select * from test_table where market = 'atl-bos' and competitor = 'delta' and dd = #2007-11-20#") Hope this helps, Stefano -----Messaggio originale----- Da: r-help-bounces at r-project.org [mailto:r-help-bounces at r-project.org]Per

Hello all, I've migrated our Maildir system from Courier-IMAP-SSL to Dovecot with SSL and now we're getting "Connection to <server> Timed Out" errors when sending mail with attachments. The mail gets sent, however it doesn't save the mail in the user's "Sent" folder. Our IMAP and SMTP servers are different. So the client sends to the SMTP server

Dear useRs, Do you know, by any chance, if it is possible to write a string in the header/footer of a pdf file created during a plot session? To make sure that I know what R script generated a certain chart, I would like to add the path to the working directory into the header/footer of the corresponding pdf file. Thank you.

Dear useRs, I would like to query an Access database through R based on a date attribute but, unfortunately, I fail to do so. For example, the table test_table of the test.mdb looks like: ID cd market competitor dd price 1 1 2007-11-20 atl-bos delta 2007-11-20 210 2 2 2007-11-20 atl-bos delta 2007-11-21 190 3 3 2007-11-20 atl-bos delta 2007-11-22

Dear UseRs: I intend to write a package to handle the basic operations a revenue management analyst has to deal with on a regular basis (e.g., demand untruncation, capacity allocation, pricing decisions, etc.). Following the directions posted by Peter Rossi (Making R Packages under Windows: A Tutorial, January 2006) I was able to build an interim package that currently consists of one simple

Dear useRs: I try to plot an rpart object but cannot get a nice tree structure plot. I am using plot.rpart and text.rpart (please see below) but the branches that connect the nodes overlap the text in the ellipses and rectangles. Is there a way to get a clean nice tree plot (as in the Rpart Mayo report)? I work under Windows and use R2.11.1 with rpart version 3.1-46. Thank you. Tudor ...

Dear useRs: Please provide me with your thoughts on an issue related to the design of a production level system. For example, let?s suppose that I need to run the same R script for a finite sequence of items (e.g., in the energy industry, I may need to asses the profitability of all gas stations in the state of Florida). For each of the items, the R script accesses some remote databases, gets

Dear all, I am working with a csv file. Some data of the file are not valid and they are marked with a star '*'. For example : *789. I have attached with this email a example file (test.txt) that looks like the data I have to work with. I see 2 possibilities ..thast I cannot manage anyway in R: 1-first & easiest solution: Read the data with read.csv in R, and define as na strings

Dear useRs: I try to use mob from the party package (thanks Achim and Co.!) to model based recursive partition a data set. The model is a logistic regression specified with model=glinearModel and family=binomial(). Running mob results in a few warnings of the type: In glm.fit ... algorithm did not converge. As I speculate that this may be due to an insufficient number of iterations I am

Dear useRs: Is there a way I could predict the terminal node associated with a new data entry in an rpart environment? In the example below, if I had a new data entry with an AM of 5, I would like to link it to the terminal node 2. My searches led to http://tolstoy.newcastle.edu.au/R/e4/help/08/07/17702.html but I do not seem to be able to operationalize Professor Ripley's suggestions. Many

Hello: Has anyone tried to model-based recursive partition (using mob from package party; thanks Achim and colleagues) a data set based on a multinomial logit model (using mlogit from package mlogit; thanks Yves)? I attempted to do so, but there are at least two reasons why I could not. First, in mob I am not quite sure that a model of class StatModel exists for mlogit models. Second, as

Dear list: I would like to recreate how the artificial data set BregFix was generated in package flexmix (thanks Bettina and Friedrich). The data set is thoroughly described in Grun and Leisch's Computational Statistics & Data Analysis 51(11) :5247-5252 but references to the appropriate seed number(s) are missing (providing these details was certainly beyond the scope of the authors'

Dear R users: Is there a way to append selectively to components of a list (if possible, loops are to be avoided)? To illustrate the point, in the example below, I would like to append 99 to vector b of the list l. > l <- list(a=c(1), b=c(2,3), c=c(4,5,6)) > l $a [1] 1 $b [1] 2 3 $c [1] 4 5 6 As you may expect, the result should look like: > l $a [1] 1 $b [1] 2 3 99 $c [1] 4 5

Customer is delivering stuff over the ocean. Time of delivery is between 1 month to 1.5 months. So customers need some sort of a tracking system ( hard to implement given the conditions ) or he needs to let tjem know when the packages arrived. Customers in Europe all have mobile phones, while senders in North America rarely have them ( they have answering machines, though ). Could someone

Dear useRs: I successfully model-based partitioned several datasets through the use of mob from the party package (thanks Achim et al. once again !!!). At times, however, the partitioning leads to terminal nodes in which the parameter estimates of the model are not significant (although the split points and in general the proposed segmentation both seem reasonable). As I do not seem to be able
