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

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 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

Full_Name: Gabor Grothendieck Version: 1.7.1 OS: Windows 2000 Submission from: (NULL) (207.35.143.81) save(x,ascii=TRUE,file("clipboard")) works but load(file("clipboard")) does not. Even better would be if save(x,ascii=TRUE,"clipboard") and load("clipboard") worked as that would provide consistency with

Hi Gabor and everybody; Thanks Gabor, with the alternative step you've told me the problem is resolved. Comparing the two procedures: Extract from the source 'character' data: > rain$ts[2039:2046] [1] "25/03/2000 22:00:00 UTC" "25/03/2000 23:00:00 UTC" [3] "26/03/2000 00:00:00 UTC" "26/03/2000 01:00:00 UTC" [5] "26/03/2000 02:00:00

To all that replied, thanks...

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, Sometimes I want to "reset" the R interpreter (as if I quit and started it again, with everything starting from scratch). The main reason for this is when I expreriment with calculations, and later form them into general functions, sometimes I forget to include variables or reset some settings which I don't notice because they are already set. This causes problems during batch

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?

Also why should that difference result in different behavior?

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

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

Consider the following R session under Windows XP Pro. Note that if we set debugging for function f then even if we reset its environment it still has debugging on. Also if we copy f to g then g has debugging; however, if we change g's environment then g no longer has debugging. Why did f retain debugging when its environment was changed but g did not?
