Comparing long species lists via Sorenson’s dissimilarity
...similar, what is 100%? I mean 50% of what? There are a number of other tests that I can run using R. These are squared euclidan, manhattan, bray-curtis, jaccard, ruzicka, (dis)similarity ratio, ochiai, cosine compliment, and Raup-crick. Would it be advantageous to run these now that I have my sorensons result? It is especially easy for me to run the Bray-Curtis all I would need to do is change the terms from ‘binary’ to ‘minimum’ and re-run. Would Bray-Curtis be a Percentage Similarity unlike the others? Here is an example of what happens when I run sorensons: #Compare Breckland with...

aggregating dates
I have a frame which contains 3 columns: "date" "defectnum" "state" And I want to get the most recent state change for a given defect number. date is POSIXct. I have tried: aggregate(ev$date, by=list(ev$defectnum), max) Which appears to be working except that the dates seem to come back as integers (presumably the internal representation of POSIXct). When I

xlims of barplot
I would like to create a family of barplots with the same xlimits. Is there a way to "read" the xlimits from the first graph so I can apply it to the subsequent ones? I have tried just taking the min and max of the x data and the plot doesn't show. cheers [[alternative HTML version deleted]]

easing out of Excel
I know enough about R to be dangerous and our marketing people have asked me to "automate" some reporting. Data comes from an SQL source and graphs and various summaries are currently created manually in Excel. The raw information is invoicing records and the reporting is basically summaries by customer, region, product line etc. With function such as aggregate(), hist() and pareto()

SQL Dates
How can I have SQL queries (ODBB/Windows) return dates (cf text) for date columns? I can successfully query and ODBC database with R. I can subsequently convert the text representations of dates in columns using as.POSIXxx functions but I figured there must be a way to achieve this at the time of the query. Any tips? paul

legend over-prints barplot bar
When I create a bar plot, the legend is obscuring the rightmost bar. I haven't found a setting that appears to affect the positioning of the legend - any tips re moving the legend would be most appreciated. paul sorenson

calculating IRR (accounting) in R
I am trying to replace a spreadsheet model of a project justification with an R script. I can't seem to track down R functions to calculate Internal Rate of Return and NPV? Am I missing something? NPV doesn't seem so difficult to calculate (at least for a regular series) but I am struggling to identify how to solve for IRR in R. It would be sufficient if it worked for a regular

networkinterface type proposal
Hi - I''ve searched around and haven''t found anyone who''s implemented a type+provider for configuring network interfaces in puppet. Does anyone have such a thing already running that''s just not on forge / github? I found some prior art (aside from the old ''interface'' type which was deleted in 0.24) but most people seem to use definitions +

I need untyped associations
I am in the process of trying to migrate to ROR from a home grown ORM, but one stumbling block is ActiveRecord''s typed associations and object ID assignment scheme. In the home grown system, I have a master table which *all* objects are packed into and a master associative table which holds *all* associations. This allows each object, regardless of type, to have a unique ID and thus it

deprecated function question
Greets all, Is there a list of functions that have been removed from flac? I am trying to compile xmcd, which is admittedly pretty old code, and it's not finding: FLAC__stream_encoder_set_write_callback FLAC__stream_encoder_set_seek_callback FLAC__stream_encoder_set_client_data FLAC__stream_encoder_init grepping through the flac headers these aren't there so I'm assuming they've

Puppet 3.0.0 bugs fixed in 3.0.1
Hi, Matthaus posted a link to the RC of Puppet 3.0.1 last week[1] but it might have gotten missed over the weekend. I wanted to follow up to call out some specific fixes in the release that the early adopters ran into and reported (for which: THANK YOU!!). First, the problem with `puppet kick` not working is fixed[2]. You will still see a deprecation warning, which is intentional, but
