can you recommend a good manual for R that starts with a data set and gives demonstrations on what can be done using R? I downloadedR Langauage definition and An introduction to R but haven't found them overly useful. I'd really like to be able to follow some tutorials using a dataset or many datasets. The datasets I have available on R are Data sets in package 'datasets':

Hello all I have a fit resulting from a call to glm. Now, I would like to extract the model frame MF, and add some variables from the original data frame DF. To do this, I need to know which rows in DF correspond to rows in MF (since some were dropped by na.omit). How can I do this? It''s probably simple but the information is hard to find.

Hello, What's about to use Icecast as win32 service? In the new installation of 2.4.0, the option for installing as win32 service isn't available. Would it be implemented in the future?

I would like to use the "row number" information returned from performing a subset command on a dataframe. For example, I would like to automatically delete some rows from a dataframe if they match a criteria. Here is my example below. data(airquality) names(airquality) subset(airquality, airquality$Month == 6) Now how do I delete the row numbers returned automatically? I

Is there a place that shows how to create two plots that are stacked on top of each other where they share a common x-axis scale, but have differnt y-axis scale? Say have the following data: airquality Stack plot(airquality$Day, airquality$Wind) on top of plot(airquality$Day, airquality$Temp). I am interested in stacking the two on top of each other with no seam, or plotting the two lines with

I would like to add a column to the airquality dataset that contains the date 1950-01-01 in each row. This method does not appear to work: > attach(airquality) > data1 <- transform(airquality,Date=as.Date("1950-01-01")) Error in data.frame(list(Ozone = c(41L, 36L, 12L, 18L, NA, 28L, 23L, 19L, : arguments imply differing number of rows: 153, 1 I can't decipher what

Is there any reason why 'attach' is not generic in R? I notice that it is in another system, for example, and I can see some applications if it were so in R. Bill Venables. Bill Venables, CMIS, CSIRO Laboratories, PO Box 120, Cleveland, Qld. 4163 AUSTRALIA

In the process of moving to the new directory structure, we might also reconsider the naming of the various index files. A simple idea would be to have an `INDEX' file in each directory where this is appropriate. E.g., we could have pkg/funs/INDEX (rather than help/pkg/INDEX) pkg/data/INDEX (rather than index.doc) pkg/help/INDEX (rather than AnIndex) or e.g. pkg/INDEX.funs

Hi folks Some proposed changes: * Fixiate the API/ABI of some libs, for the stable version, including - libxenctrl, - libxenstat, - libxenstore. As upstream don't know what abinames are for, roll own abinames. * Add libxenctrlX, libxenstatX, libxenstoreX, if abinames may be different or libxenX if the abinames should the same for all libs. * Add libxen-dev including - static

With the problem below, I've discoved that n95trt<-length(byyr$cnd95[byyr$cnd95=="tr"&!is.na(byyr$cnd95)]) does give me the correct count for the number of "tr" entries. (The same behavior occurs for the "c" level of the cnd95 factor.) It appears that byyr$cnd95=="tr" is finding both "tr" AND NA entries. Is this a bug, or is it to be

My apologies in advance for my thickness but I can't seem to solve the following, seemingly simple, data manipulation problem: I have a data frame that contains multiple factors and multiple continuous response variables, but duplicates of some factor combinations. The duplicates contain bad data, so I would like to eliminate the duplicates. I would like to retain the entire rows

Dear R list, members of my course have encountered the following error message: > slm <- lm(price ~ engsize, autoframe) Error in get(x, envir, mode, inherits) : variable "FUN" was not found [more context is given in the fuller listing below].

Microsoft Windows R users, I am operating Windows 2000 (build2195) with R1.7. It may be pertinent that I am using a dual head screen with the initial RGui filing the entire area of both screens. When starting R I use the .First() function to add menu items to the RGui interface using winMenuAdd() and winMenuAddItem(). The menus do not display until the RGui window is physically manipulated in

Dear r-devel members, It's just been brought to my attention that R permits non-unique column names in data frames -- e.g., via assignment to names() or colnames(). This behaviour is consistent with the help files (as I discovered), but it's not consistent with the behaviour of rownames() and row.names(). For example, row.names(airquality) <- rep("a", nrow(airquality))

I am not sure if this is a bug in ActiveRecord or is this the intended behavior. If it is then it does not make sense to me. In a nutshell: If you change an aggregate object attribute created via composed_of method (see Agile Web Development - Second Edition Chapter 17 page 313 onwards) and then save the model, the change to the model (composite attribute specifically) will not be saved UNLESS
