...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.

Hi, Please someone let me know that the installation of both R for Windows 2.12.2 and MS office 2010 on the same system will interfere each other or not. In short, are these two tools compatible to each other? Thanks in advance. Best Regards, Vedajit [[alternative HTML version deleted]]

Hello there, would you please look into my codes? Here I have following: > set.seed(100) > samp <- sample(c(1,-1,0), 20, replace=T); samp [1] 1 1 -1 1 -1 -1 0 -1 -1 1 -1 0 1 -1 0 0 1 -1 -1 0 Here I want to calculate the length of each unique number for above vector. How can I do that? Thanks in advance [[alternative HTML version deleted]]

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

Hi, I've been able to get the data _of every individual_ into a graph (there are 16 lines), but I have a few more questions... 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

Fellow R programmers, I'd like to submit SQLDF statements with R objects as column names. For example, I want to assign "X" to "var1" (var1<-"X") and then refer to "var1" in the SQLDF statement. SQLDF needs to understand that when I reference "var1", it should look for "X" in the dataframe. This is necessary because my SQLDF

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
