similar to: Histogram for grouped data in R

Is there a canonical way to check if all elements of a vector or matrix are the same? Solutions below work, but look hackish to me. > x <- rep(1, 10) > all(x == x[1]) # == operator does not provide for small differences [1] TRUE > isTRUE(all.equal(x, rep(x[1], length(x)))) # ugly [1] TRUE Best, Vincent -- Vincent Goulet, Associate Professor ??cole d'actuariat

Is there any neat way to add a curve (frequency function or the like) to a histogram or other plots? I haven't found one yet... Robert

[Version fran??aise plus bas] To the R community, A quick word to announce the publication of my document "Introduction ?? la programmation en S". It is available in the French section of the Contributed Documentation page of CRAN. Many of the documents or books currently available on S-Plus and/or R present the software in a statistical analysis context. My document rather focuses

Dear R developers, I'm a former APL programmer. In that language, the "take" (up arrow) and "drop" (down arrow) operators were extensively used to, well, take and drop elements of vectors. Functions head() and tail() are equivalents in R for the "take" operator, but nothing seems to mimic the "drop" operator. I think it would be useful. For

Dear All, A simple question: packages like fitdistr should be ideal to analyze samples of data taken from a univariate distribution, but what if rather than the raw data of the observations you are given directly and only a histogram? I was thinking about generating artificially a set of data corresponding to the counts binned in the histogram, but this sounds too cumbersome. Another question is

Hy all, Is there a direct way to build the complete function call of an arbitrary function? Here's what I want to do. A function will build a function which will itself call a probability density function for some law given in argument to the first function: > f("gamma", 1000) will return, say, function(x, shape, rate, scale = 1/rate) dgamma(x + 1000, shape, rate,

I created a type of object similar to a data frame. In some circumstances, It needs special methods for "[" and "[<-" and rbind() (but not cbind()). Then I found this in the cbind()/rbind() man page: The method dispatching is _not_ done via 'UseMethod()', but by C-internal dispatching. Therefore, there is no need for, e.g., 'rbind.default'.

Dear R People: I have finally seen the error of my ways and have decided to use ESS for R and S + stuff. However, I have a question right from the beginning. I'm somewhat confused by the installation instructions. Do I install XEMACS or ESS first, please? Windows XP R Version 2.0.1 (S + 6.2) Thanks so much!

Hi, how can I treat data organised in classes and frequencies? Ex. class frequency 20-23 9 23-25 7 26-28 5 29-31 5 32-34 3 Thanks Angelo Scozzarella

Package grDevices has a function cm() to convert from inches to centimeters. Its definition is: cm <- function(x) 2.54*x As far as I can tell, the function is not used anywhere in the R sources (I grepped for "cm(", "cm)" and ", cm".) I did not check for all packages on CRAN, though. May I propose to remove this apparently useless function from the sources? [I

Hi all, Is there an option in Sweave to avoid it from stopping on a code chunk with an error? (I purposefully want to include code with an error in class notes.) I suspect the answer is "no" and that I will be pointed to options("error"). That'd be fine, but which error parameter will just "do nothing" in case of an error? Thanks in advance! -- Vincent

Dear developeRs, Compilation of the latest version (0.9-5) of my actuar package fails with r-release MacOS_X ix86 on CRAN; see http://www.R-project.org/nosvn/R.check/r-release-macosx-ix86/actuar-00check.html All errors come from accented letters in comments in latin-1 encoded files (except hierarc.R which is in UTF-8, my bad). Encoding is declared as latin-1 in DESCRIPTION. The package

Hi, From the R Language Definition, Section 3.4.1: "If i is positive and exceeds length(x) then the corresponding selection is NA. A negative out of bounds value for i causes an error." (This is also mentioned in S Programming, footnote of page 24.) Can someone please provide an example triggering the error? Looking in src/main/subscript.c I could not find exception handling for

Hi all, Could anyone point me to one or more examples in the R sources of a C function that is called without knowing in advance what will be the length (say) of the output vector? To make myself clearer, we have a C function that computes probabilities until their sum gets "close enough" to 1. Hence, the number of probabilities is not known in advance. I would like to have an

We obtained some disturbing results from convolve() (inaccuracies and negative probabilities). We'll try to make the context clear in as few lines as possible... Our function panjer() (code below) basically computes recursively the probability mass function of a compound Poisson distribution. When the Poisson parameter lambda is very large, the starting value of the recursive scheme ---
