Organisation of medium/large projects with multiple analyses
Dear all, I'm still new to R, but have a fair experience with general programming. All of my data is stored in postgresql, and I have a number of R files that generate tables, results, graphs etc. These are then available to be imported into powerpoint/latex etc. I'm using version control (subversion), and as with most small projects, now have an ever increasing number of R scripts,

RODBC and NULL values
Dear All, Writing sooner than I thought I'd need to. I'm using R 2.4 on Mac OS X, with RODBC, PostgreSQL 8.1 and Actual's ODBC driver. I have all my data in Filemaker 8.5, but it is automatically exported into PostgreSQL for analysis as Filemaker's ODBC and JDBC access is awful, slow and has a tendency to crash. I have disability data where for each patient there is a survival

Sweave, R and complex latex projects
Hello all, I've been able to use R very successfully to run simple statistics and generate the plots I require. I've been evaluating Sweave, and have hit upon a small problem that I don't seem to be able to workaround. Sweave runs very well for single file latex documents, but I have a complex thesis made up of several parts and chapters. These are arranged with a master latex file

Problem accessing "row number" from subset on a dataframe
I would like to use the "row number" information returned from performing a subset command on a dataframe. For example, I would like to automatically delete some rows from a dataframe if they match a criteria. Here is my example below. data(airquality) names(airquality) subset(airquality, airquality$Month == 6) Now how do I delete the row numbers returned automatically? I

Can R handle medium and large size data sets?
Dear R experts, Is it true that R generally cannot handle medium sized data sets(a couple of hundreds of thousands observations) and threrefore large date set(couple of millions of observations)? I googled and I found lots of questions regarding this issue, but curiously there were no straightforward answers what can be done to make R capable of handling data. Is there sth inherent in the

Package Installer Fails in OSX 10.5 Leopard
Hello all, I apologize in advance if this is not the correct list to post these sorts of issues. When attempting to install the latest stable build of R (2.6) or the most recent nightly build from R.research.att.com, the installer disables the ability to actually install R or any of the other bundled frameworks (i.e. the list is unchecked and grayed out). Before I start trying to either coerce the

Sweave and font problems
Dear All, Having now successfully started using Sweave, I have just noticed an odd side effect with fonts. Using plain LaTeX, I have had no problems using \usepackage{palatino} or \usepackage{times} and the font correctly changes. However, once I convert the tex document into Snw, and run it through R CMD SWEAVE, LaTeX seems to ignore this package directive. The LaTeX log suggests the font

Aggregation of data frame with calculations of proportions
Dear all, I have been stuck on this problem, am rather struggling and would appreciate some advice if anyone can help. I apologise if this is a bit long-winded, but I've tried to limit it to the bare essentials, but don't know how to make it more generic! I have some slightly odd real world data that I'm looking at representing number of positive diagnoses for different diseases,

Produce a multiple formats graphic
Is it possible to produce the same graphic in different formats in one shot? Now if I want to produce the same graphic in pdf, ps and jpeg I run the producing code, but I change the graphic device, and I choose successively : pdf(...) ps(...) jpeg(...) So in this case I run the same code 3 times, or I have to choose a format and use converters... Is it possible to produce the 3 graphics in once

Lattice book
Dear all, I haven't seen this mentioned and presumably Dr. Deepayan Sarkar is too polite to advertise! I just received a flyer from Springer: A new book on Lattice released today!! http://www.springer.com/statistics/computational/book/978-0-387-75968-5?cm_mmc=NBA-_-Apr-08_UK_1753460-_-product-_-978-0-387-75968-5

OK - I got the data - now what? :-)
OK, I guess I'm getting better at the data part of R. I wrote a program outside of R this morning to dump a bunch of experimental data. It's a sort of ragged array - about 700 rows and 400 columns, but the amount of data in each column varies based on the length of the experiment. The real data ends with a 0 following some non-zero value. It might be as short as 5 to 10 columns or as many

R: Query an Access database based on a date attribute
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

Phil Spector's book
Since we're on the topic of book reviews, I just received Phil Spector's new R book called "Data Manipulation with R" and it is also quite a nice book. I haven't gone through it all and I won't give a detailed review but I have gotten a lot out of the first 100 pages that I have read. Note that I've been using R for almost 1.5 years so , for me, it's a

Density estimation graphs
Dear all, I'm struggling with a plot and would value any help! I'm attempting to highlight a histogram and density plot to show a proportion of cases above a threshold value. I wanted to cross-hatch the area below the density curve. The breaks and bandwidth are deliberate integer values because of the type of data I'm looking at. I've managed to do this, but I don't think it

Show number at risk on Kaplan Meier curve
Dear all, I'm using the "survival" package with R 2.4.0 on Mac OS X 10.4.8. I have two core statistics books (one of which is Altman's medical stats book) which suggest showing the number of individuals at risk at different time intervals on the Kaplan-Meier curve. My plot shows two curves that later cross, because of one significant outlier. I have two queries: Is there an

Getting estimates from survfit.coxph
Dear all, I'm having difficulty getting access to data generated by survfit and print.survfit when they are using with a Cox model (survfit.coxph). I would like to programmatically access the median survival time for each strata together with the 95% confidence interval. I can get it on screen, but can't get to it algorithmically. I found myself examining the source of print.survfit to

New kex organisation and user options.
I'm in the process of updating my GSSAPI patches to the 2.9 release. However, I've run into a slight problem with managing to get user options to play nicely with the way that the kex code is now organised. With the GSS kex its possible for the user to specify whether they want to delegate their credentials to the server or not. This option is used only on the client side (and so is
