Database abstraction
...think) designed as to support the addition of more complex logic at any stage (generation, preparation, compilation, formatting) withouth becoming spaghettized. I've written a reasonably-sized test suite that covers most of the functionality. The code is hosted on github - https://github.com/rtirrell/databasr. Feel free to fork, critique and/or use. I've taken some pains to ensure that interface will remain relatively stable.

Hello there, would you please look into my codes?

A question about data frame
A very simple question. With a data frame like this: > n = c(2, 3, 5) > s = c("aa", "bb", "cc") > df = data.frame(n, s) I want df$s[1] or df[1,2], but how can I get rid of the extra line in the output about the factor levels: > df$s[1] [1] aa Levels: aa bb cc Thanks, Gang

How do I neatly get the average weights of each group (PC3/CO, PC3/FO, FADU/CO and FADU/FO) and make a graph of four lines. How do I exclude the first column (which is each animal's internal description) - there is a spot on the x axis labeled 1 - that is blank and

R5 multiple inheritance
Hi all - Is anyone aware of any solutions (or workarounds) for R5 classes that allow multiple inheritance? Alternatively, if anyone has ideas about how where I may be able to start, I'm willing to delve into dark magic. It's presently possible to give multiple superclasses in contains, but method dispatch only behaves correctly for the first of them. I don't *think* this has changed
