similar to: how to specify format of floats for the output file

Hi, I am not sure if this is a bug or a non-implement feature of text-drawing functions with TeX-style expression, but hat() and some of its equals does not get the right "bounding boxes" if they are put in sub- or superscripts. For instance, for the expression 'b[hat(a)]' the hat() seems to shift 'hat(a)' too much to the right of 'b'. Try the below example and

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

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

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

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

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

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.

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 ...

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 ...

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

Where should the setClass() ('methods' package) calls be placed in a package? I try to follow a one-class-one-file principe, but since setClass("ClassA", "ClassB") has to come a after setClass("ClassB", [snip]) it is not possible to fully follow this rule. So the best I can do now is to put all setClass() calls in a file named "000.R" (I know this

I use smooth.spline(x, y) in package modreg and I would like to get value of penalized log likelihood and preferable also its two parts. To make clear what I am asking for (and make sure that I am asking for the right thing) I clarify my problem trying to use the same notation as in help(smooth.spline): I want to find the natural cubic spline f(x) such that L(f) = \sum_{k=1}{n} w[k](y[k] -

Is there a weighted median function out there similar to weighted.mean() but for medians? If not, I'll try implement or port it myself. The need for a weighted median came from the following optimization problem: x* = arg_x min (a|x| + sum_{k=1}^n |x - b_k|) where a : is a *positive* real scalar x : is a real scalar n : is an integer b_k: are negative and positive scalars

Dear all, I can't see how setGeneric() works. I know perfectly well how to define library(methods); setClass("Square", representation(side="numeric")); # Will become the default method. getArea <- function(object) { stop(paste("Method getArea() is not defined for this class:", data.class(object))); } setMethod("getArea",
