Hello, What options are available for me to debug my R scripts? For example I normally do something like >source("myfunctions.R") >function1("height", "weight") myfunctions.R is a large R source file that contains many functions. function1 is the "main" function in myfunctions.R. It calls many other user-written functions that are also in

Brian Ripley recently replied to a comment of mine by referring to a function 'assignInNamespace', which I had not heard of. Is there a good write up on name spaces in R? There are little tidbits in the manuals on the R site, but I found nothing substative. I'd like to understand these better. Terry Therneau

Hello! I would like to know if there are already programmed statistical tests for data under serial dependence, for example, considering the variance inflation factor? Thank you very much Best regards Rosa

Dear useRs, Is there a package or a function able to simulate models with sets of differential equations? Where we could input our model and give R some value to start with and it would generate the graphs?

Dear R user group, I wish to plot small pie-charts to specific coordinates in a e.g. scatter-plot: E.g.: > plot(rnorm(100),rnorm(100)) > points(1,1,col="red",cex=4) -> I wish to put pie(c(2,3)) at the position of the red circle... How can I do this efficiently? Thanking you and wishing you a wonderful Sunday! Georg. ************************** Georg Ehret Johns Hopkins

Just wondering: it appears that "srt" does not accept a vector of values, just a single value. I ended up using tapply() as the following code snippet shows, so it's not a major problem. I was justa little surprised that this argument (srt) differs from things like "labels," "lty," "col," and so on, all of which accept (and recycle as needed

Hi, I want to insert a small figure into a bigger plot. I saw people are doing this all the time, but I just could not figure out how to do it in R. Thanks for your help! Jinfeng Zhang

Group, I am new to R. In my work as a program evaluator, I am regularly asked to estimate effect sizes of prevention/intervention and educational programs on various student outcomes (e.g. academic achievement). In many cases, I have access to data over three or more time periods (e.g. growth in proficiency test scores). I usually have multiple independent and dependent variables in each

Should I be able to use axis() on a barplot? i have a data.frame, the first 3 values of which are: > c[1:3,] median mean A1 56.5 58.50000 A61 73.0 73.00000 A62 63.0 63.00000 > str(c) `data.frame': 19 obs. of 2 variables: $ median: num 56.5 73 63 161 51 55 44.5 22 54 49 ... $ mean : num 58.5 73.0 63.0 161.0 47.5 ... if I do barplot(median) and then try

Hi R users, 1) How does one show confidence-intervals in a barchart and use rownames for labels on the y-axes? I have looked at "plotCI" in "gregmisc" package . But it does not seem to produce something like a barchart. The statistic, error, upper-bound, and lower-bound are in a dataframe. 2) How to show CI in a barchart either using the statistic and, either (a)

Hello, can anyone tell me if R has any special function for simulating the structure of human populations? Something like the genetic algorithm? I need to simulate a sample of a population with a specific structure. Is there something on R that can help me? Thanks to everyone. __________________________________________________________

I have a few questions for R: 1. Other than using a built-in function such as mean(), how do I know if it is installed in my current version of R? 2. To get help in R, I can use several ways: ?sort help.search("sort") help(sort) apropos("sort") the help menu are there any other ways to get help? 3. When I see a help menu for a function, does it mean the function is

Dear R People: Could someone direct me to some documentation on the difference between S3 and S4 classes, please? For example, why would a person use one as opposed to another? Maybe pros and cons of each? Thanks in advance! R Version 2.2.0 (I'm downloading the new one this afternoon!) Windows. Happy New Year!

Hello, I am a beginner with R. I read many tutorials and the FAQ but I cannot solve my problem. I use barplot() to view my graph. I try to get more interval marks on y axis. I wasn't able to find options in 'help(barplot)' or 'help(par)' to do this with barplot(). I seek for another option to print y values on my bars like on the graph of the R homepage:

This has been asked before, but all the answers are hidiously complex. The legend.text=TRUE option of barplot is almost exactly what I need, except I need a legend.placement='tl' (top left) option. This option would be in contrast to the default placement which we could call 'tr' (top right). Anyone know how to edit the barplot code to make this change? Could someone like me

Hello, Can anyone tell me how to label individual bars on a barplot? I want to put an "*" or letter ABOVE the bar to denote statistical significance. Is this possible and how?

Dear R users, I would like to combine lattice plot (xyplot) and standard R plot (plot and plotCI) in an unique figure. I use the function "par()" to combine plot and plotCI and I use the function "print()" to combine xyplot. I tried to use these functions to combine xyplot and plotCI and plots but they do not work. Does anybody know how I can do this? Thank you very much in
