Hi, just in the process of updating my packages for R v2.0.0 and I have not had time to followed the R v2.0.0 discussions so maybe my questions have already been answered. A concern I have is that when creating packages they should be backward compatible with R v1.9.x for a while until all users and computers has migrated to R v2.0.x. It is pretty straightforward to setup my packages so that

What about adding the argument 'flush=FALSE' to read.table() for the option to ignore trailing elements on each row? This feature already exists in scan(), which is called internally by read.table(): flush: logical: if `TRUE', `scan' will flush to the end of the line after reading the last of the fields requested. This allows putting comments after the last

With tryCatch() it is possible to catch interrupts with tryCatch(). Then you can use a 'finally' statement to clean up, release resources etc. However, how can I "protect" against additional interrupts? This is a concern when the hold down Ctrl+C and generates a sequence of interrupts. Example: tryCatch({ cat("Press Ctrl+C...\n"); Sys.sleep(5); }, interrupt =

Dear R developers, I will ask a very straightforward question concerning UseMethod's future, because people depending on my code wonder what will happen to it next. In R v2.0.1 NEWS it says o The undocumented use of UseMethod() with no argument is now formally deprecated. and in the R v2.0.1 help(UseMethod) it says 'UseMethod' accepts a call with no arguments and tries to

Hi, I'm creating a lot of tables in a file for inclusion in a Latex document. When I try to compile that document there is an error "too many unprocessed floats." Is there a way to correct this? Also, in a Latex table I want R to put in a $\beta$ in the caption, but it puts a weird system character instead of the \b Brian

When using write.table() to write data frames the integer columns are padded with unnecessary spaces (0x20) so that these columns are right align if you look at them in a text editor. However, I think it is quite a vast of file size. For instance, I am reading a tab-delimited 4200kb microarray data file and writing it back verbatim using write.table() and it becomes 5100kb, a 20% increase. Is this

Before reinventing the wheel, is there a package for working on (nice) sets and intervals, where one can for instance check if a set of intervals contains a scalar, taking the union and intersection of some intervals etc? Example: # Defining the set i = [1,2) + [3.5, 10] i <- c(1,2, 3.5, 10) attr(i, "include") <- c(TRUE, FALSE, TRUE, TRUE) x <- 0:12 # Get

Hello, I wonder if it is unwise to name a bundle the same as one of its packages. For instance, I now have a huge package called 'aroma' that I basically want to split up in several smaller packages, say 'aroma.core', 'aroma.io', 'aroma.explore', 'aroma.trial', 'aroma.deprecated' etc, which simplifies maintenance but also the overview. For

I'd like to write some numbers to an external file that looks "pretty" (e.g, decimal points aligned, same number of decimals). For example, if using sprintf(), "%5.1f" can be used to specify the format of the float to be printed on screen. How can I do the same if I want to write an output file instead? I have tried cat and write.table, but none of them worked so far.

Hallo! I would like that the internal package functions does not appear in the documentation. I placed they names as aliases in the file nameofmypackage-internal.Rd as advised. After R CMD check (which runs neatly) they are still listed in 00Index.html. Is there no way to hide internal functions from the doc? Have I overlook something? Sincerely Eryk. Dipl. bio-chem.

Hi I am facing a problem where I would like to import a TIFF image (of spots on a nylon filter) into R (into a matrix for example). When plotting the matrix using fx. scatterplot3d I would then be able to see how the pixel-intensities are distributed in "spot-areas" on the filter - which would be very helpful. Does anynone know of a way to do this? Best regards, Peter Hagedorn ...

I think this was asked recently but I can't find the item. Is it possible to find the colour at a point on a graphics page? I want to estimate the area of a complex shape by colouring it then random sampling from an enclosing box ...

In nonparametric regression and density estimation, something like \hat{f'}(x) [LaTeX] is very natural. In all S dialects, hat(f') is invalid syntax, and hence one cannot use something like plot(1, main = expression(hat(f'))) I can say something like plot(1, main = expression(widehat(paste(f, "'"))), cex.main = 3) but that (the R code, not the plot result)

I am using 32-bit R 3.1.2 on Windows 7. I recently conducted an `R CMD check --as-cran` on a recently-developed package and received only the 'New submission' note. Research on StackOverflow and on R-devel suggested this could be ignored. I also used devtools::build_win() and received no notes or warnings, other than the one mentioned previously. Lastly, I conducted an `R CMD check` with

Dear all, I am stuck at applying loop function for creating separated plots. I have coding like below: dataset.table <- table(data.frame(var1=c(1,2,3,1,2,3,1),colour=c("a","b","c","c","a","b","b") )) kk = function(f) { ls=as.character(f) pie(dataset.table[ls,],main=ls)

Thompson's Manual to Accompany Agresti's book refers to a package named "repeated". It's not on CRAN from what I can see. I have seen rpm's for it. Where is the best place to download this package? Rick B.
