similar to: R code to generate Sweave input ? Sweave squared ?

DeaR list, Has anyone tried to mix the Sweave paradigm with the Markdown[*] (and co.) syntax? Would this be hard to implement? My tiny understanding of Sweave is that one can define new drivers for the text part, while some functions that deal with the R code would not require any modification. Here's the reason I'm interested in Mardown for a driver. I've been orbiting

Dear R-helpers: I am an R newbie and have a question related to writing functions that accept unlimited number of input arguments. (I tried to peek into functions such as paste and cbind, but failed, I cannot see their codes..) Can someone kindly show me through a summation example? Say, we have input scalar, 1 2 3 4 5 then the ideal function, say sum.test, can do

All, Has anyone experienced a problem with the Polycom 650 phone freezing when you try to do a transfer? I am running asterisk 1.2.20.1 with Polycom SIP version 2.1.1.0052 and boot rom version 3.2.3.0002. I have Polycom 501 phones that work perfectly with the same software versions. The 650 phone; when I hit transfer the caller is placed on hold and the phone is still operational. As

Hi, I wonder whether there is a way to generate a polygon (a triangle in my case) with color gradient using grid.polygon() in package grid? I tried something like library(grid) grid.polygon(x=c(0, 0.5, 1), y=c(0.5, 1, 0.5), gp=gpar(col=NA, fill=colorRampPalette(c("green", "lightgray"), space="Lab")(200))) But am only

Hi all! I''m trying to shape traffic in a dorm''s network (4 mbit symmetrical internet link, about 200 computers, heavy p2p usage). The router is a p4xeon running linux 2.6.9 with the qnet patches (http://kem.p.lodz.pl/~peter/qnet/). When I activate ip_forward I get >20% packet loss and a lot of duplicates. Any ideas? I attach my shaping script. Thank you very much in advance,

Dear R-users, I am trying to use the grid.text and expression functions to display several character strings and plotmath text on a viewport. Some strings can include a variable portion (PI.limits in the following example), which I thought could be implemented by combining the bquote and the expression functions. Unfortunately, my expressions do not seem to be evaluated. I would greatly

Hi, I've used the following command in qplot qplot(a$V1,geom="histogram",binwidth=0.15,fill = factor(a$V2),ylab="Frequency",xlab="Rate"); but the title in the legend shows up as factor(a$V2)...how can i change this? -- Rajesh.J [[alternative HTML version deleted]]

Dear R-helpers, I have a list containing 5000 elements, each element is a dataframe containing one ID column (identical over the 5000 dataframes) and 9 numeric variables, e.g. ID VAR1 VAR2 VAR3 ... VAR9 I would like to create a new dataframe containing the ID column and the mean values of the 9 numeric variables. So, the structure of this new dataframe would be identical to the structure of the

Dear list, I've written a function that plots subjects. Something like: myplot <- function(subject) { plot(subject) } Subjects are vectors, e.g. ... s1 <- c(200,200,190,180) ... and plotting them works fine, e.g. ... myplot(s1) Now I want to have "s1" etc appear in the plot title, but I don't know how to refer to this generically (the object "name"? I tried

Dear R-community, using R.2.9.1, how do you put reference lines or grids into the _background_ of a plot? For example: barplot(3:1) abline(h = seq(0.5, 2.5 ,0.5), col = "red", lty = "dashed") -> The lines are before the bars (and the line parts going through the bars might be considered as "chart junk", I suppose). Now, in this toy example I could just do the

Hi I have the following function which should return the name of FUN: myFUN <- function(FUN) { return( THE_NAME_OF_FUN(FUN)) } Is it possible? What do I have tio use here instead of THE_NAME_OF_FUN?

Dear R-Help subsribers, upon running into a wonderful ggplot2 package by accident, I abruptly encountered another problem. Almost every command run with ggplot2 results in some sort of error. The one below is far the most common one. Kind people from ggplot2 mailing list couldn't manage to solve the problem, so I'm re-posting it here to try my luck. I will recommend myself for any tips
