In the Lua language they have put the entire source on the net in such a way that you can easily browse it. Go to: http://www.lua.org/source/5.0/ to see what I mean. One of the nice things about R is that if you want more info on a function than in the help page you can just type the name of the function at the R prompt and you get its source, at least if it itself was written in R.

Hi, I'm new to R and would like to know, how one can populate the list with array data. I'm reading a tab separated table in R. The data in the table looks something like this. #Table Data Comp    A    B    C Extracellular    103    268    535759 Nucleus    45603    47783    442744 #R code myData <- read.table("table.data",                 header=T,                

I have found the use of save( ) and attach( ) when supported by a pair of functions written by my colleague John Miyamoto, move( ) and rm.sv( ) quite useful in managing (1) collections of useful homebrew functions, (2) project workspaces, and (3) "packages" under development. An .Rdata file containing these and other handy functions together with a brief supporting document can be

I just updated my copy of Cygwin to the latest version, and now Windows builds are failing on that machine. The only parts of the R toolset I changed were the Cygwin dlls. I haven't tracked down exactly what the problem is, and probably won't be able to do so for a few days. So if you're a Windows user thinking about a Cygwin upgrade, be prepared for problems...

I tried it using file and it seems to work for saving: > data(iris) > con <- file("clipboard","w") > save(iris,ascii=T,file=con) > close(con) > readLines("clipboard") ... lengthy output follows which seems correct ... but not for loading: > con <- file("clipboard","r") > load(con) Error in load(con) : loading from

Consider the following example: # substitute a with b in the indicated function. Seems to work. > z <- substitute( function()a+1, list(a=quote(b)) ) > z function() b + 1 # z is an object of class call so use eval # to turn it into an object of class expression; however, # when z is evaluated, the variable a returns. > eval(z) function()a+1 Why did a suddenly reappear again

Hi I'm using R 2.0 in SuSE 9.2. When I plot data as a boxplot, the boxes appear on the plot in alphabetical order (of group) rather than the order in which they appear in the data. So far, the only thing I can do to fix this is to prefix the group labels with a,b,c...etc to trick R into plotting them in the right order. Can sorting be turned off? How should I address this sensibly? Thanks

Hello all, Now that I am subscribed to the list I can reply at last :) Kelly, thank you for the comprehensive write-up and pointers to sources and the Arduino lib and example. This took me into a rabbit hole and I've spent entirely too many hours browsing through the NUT sources and USB/HID/PowerDevice specs. Jim, thanks for the comprehensive write-up and all the work you do on NUT. This

Hi, Are there labeled break statements in R? i.e., something along the lines of TOPLOOP: for(i in 1:m) { for(j in 1:n) { ... if(condition) { break TOPLOOP } } } Thanks, Roger

I'm trying to write an automatic check of the toolset installation for R. It'll get all the tools to print their version numbers, and complain if they aren't acceptable ones. However, I can't see how to get sh to print version information. Is there some way to do it? The sh I'm worried about is the one that comes with Cygwin, if there isn't a standard approach. Duncan

I gather that the pipe problem is a difficult one to solve since its highly desirable (at least for me) to be able to use Windows pipes yet its been outstanding since the previous R release. I have one idea on a possible workaround and associated feature and I wonder if this feature is feasible? I just noticed that z <- system("c:\\a.bat", intern = TRUE, invisible = TRUE) is

One can perform a for loop without indices over the columns of a dataframe like this: for( v in df ) ... some statements involving v ... Is there some way to do this for rows other than using indices: for( i in 1:nrow(df) ) ... some statements involving df[i,] ... If the dataframe had only numeric entries I could transpose it and then do it over columns but what about the general case?

Hello all, I think there was a very good reply about an Arduino-based controller for a DIY UPS here. The project you posted to, with an Arduino presenting as a Megatec protocol server, also seems interesting. Here I'd like to reply to one point not covered before - DMF. As a short and quick reply - unfortunately no, you can not use it with stock upstream NUT at the moment, and not for

When I alter the levels of a factor, why does it alter the names too? f <- factor(c(A="one",B="two",C="one",D="one",E="three"), levels=c("one","two","three")) names(f) -- gives [1] "A" "B" "C" "D" "E" levels(f) <-
