Dear R users, I need a function that gets a number and returns its number of actual decimal places. For example f(3.14) should return 2, f(3.142) should return 3, f(3.1400) should also return 2 and so on. Is such function already available in R? If not, could you give me a hint how to achieve that? Many thanks in advance. -----------------------------------------------------------------

Dear R users, I need to add minor axis ticks to my graph. In traditional R this is easily achievable by simply adding a second axis with the minor ticks. But how to do that in trellis? I am already out of ideas. Any suggestions will be appreciated. Best regards, Martin ----------------------------------------------------------------- ?????????? ??????????? ? ?????? ?? ??????????

Good morning! I recently implemented a KD tree in JAVA for faster kernel density estimation (part of the code follows). It went well. To hook it with R, however, has proved more difficult. My question is: is it possible to implement the algorithm in R? My impression seems to indicate no as the code requires a complete class-object framework that R does not support. But is there an R package or

Hello, I am trying to conduct a bi-variate ripley's k using the k12hat function in the splancs package (found here http://rss.acs.unt.edu/Rdoc/library/splancs/html/k12hat.html). Although, I receive an error when getting to the bboxx part of the code: poly <- list(x=c(fire4$X, nar4$X), y=c(fire4$Y, nar4$Y)) plot(seq(5,80,5), sqrt(k12hat(fire4), as.points(nar4),

Not sure if this is the right place to report this, but: Am using ggmap to generate a map of a bounding box from 161 latitude/longitude pairs and the code crashes R (in ess). Data is at http://analysis.d8u.us/~hdiwan/plotSource.csv and the code to read it is below. I'm not sure if ess, emacs, ggmap, R, or my laptop is to blame. Here's the code: > rmc <-

Hello friends of R, My name is Toni, i'm 25 and I'm working on the Meteorological Investigation team from Balearic Islands.

In a variety of graphic applications, I plot some data, together with arrows representing variables or linear transformations of variables as vectors in the same space, as in a biplot. In my applications, the scale of the arrows is arbitrary -- all that matters is relative length. I'd like to blow them up or shrink them to fit the available space in the plot. The origin is typically at

Dear all, I would like to use R to create a map , with some points with no copyright. I am trying to use the open street map interface of Rgooglemaps package.

Hi, I ran into the following peculiarity involving S4 method dispatch and namespaces. I develop a package which have a namespace and which depends on 'pixmap' package, which itself does not have a namespace. Now, in my package I have a class which has a slot for objects from class "pixmap" and I want to have a "plot" method for this new class. Not to clutter the

Hello all, I will introduce myself, I'm french, about 34 years old and works for a mechanic company. I've discovered linux in 2006 and I'm really enjoyed by all the things that can be done with.

Dear all, I write to the community to know if other people expierenced the same problem. I want to save a rgl scene where I plotted a 3d cloud of spheres whose radius is set proportional to a given variable and coloured by another group variable and with 95% ellipsoids for distribution of any group. I had no problem at all for coding but I had two problem when saving the scene (in any format)

Hi UseRs - I am new to R, and could use some help making out-of-sample predictions using a boosting model (the mboost command). The issue is complicated by the fact that I have panel data (time by country), and am estimating the model separately for each country. FYI, this is monthly data and I have 1986m1 - 2009m12 for 9 countries. To give you a flavor of what I am doing, here is a simple

Dear R-Users, Are there any packages that enable the modifications of highlighted areas / annotations in pdf documents? It seems feasible - I have explored some R code (see below). However, I would rather avoid to reinvent the wheel. The problem: When highlighting pdf-documents with Microsoft Edge, the bounding box is sometimes misplaced, and quite ugly so. It also lacks the ability to draw
