In S-Plus, I can look at the structure of a function (for example, hist) simply by entering hist <RETURN> however, if I do this in R, I get the response function (x, ...) UseMethod("hist") <environment: namespace:graphics> How can I inspect the structure of a function in R? ------------------------------- Richard Dybowski 143 Village Way

Given a matrix m, I would like to obtain a boxplot of the columns of m; in other words, boxplot(list(m[,1],...,m[,ncol(m)])). At the moment, I am using colpart <- function(m){ L <- list(rep(0,ncol(m))) for(i in 1:ncol(m)){ L[[i]] <- m[,i] } return(L)} boxplot(colpart(m)) for this purpose. Surely there must be a more eloquent way! Richard

Dear colleagues, Can anyone of you tell me how to write a "nabla" symbol in an R graph? Thanks in advance, Nuno ______________________________________________ Centro de Oceanografia - IO-FCUL, Portugal Center for Quantitative Fisheries Ecology - ODU, USA [[alternative HTML version deleted]]

Dear R experts- I'm running R 1.2.3 (2001-04-26) on Linux. I need to get special symbols, such as a circle with a dot in it as used to indicate Solar units in astronomy, into my plot axis labels. How can I do this? Using the R documentation on the Hershey font sets, one can plot a Solar symbol within the world coordinates of a plot like this: >plot(1:10,1:10)

This was reported to me by a colleague in China, so I may not be reproducing exactly what they are seeing (which I suspect is rw2011), but this is what I see: > version _ platform i386--netbsdelf arch i386 os netbsdelf system i386, netbsdelf status major 2 minor 1.1 year 2005 month 06 day 20 language R > help(Hershey) : : If the 'vfont' argument

Dear R Helpers: I am trying to annotate a plot. The following code snippet works, but it is kind of a kludge since it adds the partial derivative symbols after creating the plotmath frac(). Is there a more elegant way to write a partial derivative? dev.off() plot(NA, xlim=c(-3,3), ylim=c(0,1.6), xlab="", ylab="", tck=-0.015) text(1.6, 1, expression(paste("slope =

Hi all! I have a little question concerning quadprog. To make it simple I'll start by stating the problem: I want to minimize h(d,delta)=0.5d^T B d +nabla(f(x))^T d +rho*delta^2 With respect to d\in R^n and delta \in R. I obviously have constraints (depending on both d and delta). Solve.QP does give me a good result for d but I cannot obtain anything for delta. Simce dim(Dmat)=n and

I am trying to get R-2.2.1 to pass make check on an AIX 5.2 at work (I know R-2.2.1 is not the latest release, but I encountered make errors in my attempts to install either R-2.3.0 or the R-patched_2006-05-10 on the version of AIX I am on. I will post those errors in a separate posting from this.) So far, configure and make finish without error for R-2.2.1 using gnu make, gcc-4.1.0, and

Hi, I am trying to change the number of the ticks on each axis, but every time I can not succeed and receive the error message shown below even I use the default values: >plot.mts(infldata1[,3:4],lty=c(1:2),plot.type="single",lab=c(5,5,7)) Error in axis(side, at, labels, tick, line, pos, outer, font, vfont, ...) : location and label lengths differ, 6 != 3 Thank you for

Hello, I remarked that the function ## Default S3 method: text (x, y = NULL, labels = seq(along = x), adj = NULL,pos = NULL, offset = 0.5, vfont = NULL,cex = 1, col = NULL, font = NULL, ...) accepts vectors of arguments (of the same length) except for the parameter adj. When passing a vector of information for adjusting the labels, only the first value is taken. Any special reason for this ?

yes I have tries, and nothing.

Hi all user R, My simple question is...I have a vector of names of predictors, text<-c("datem","cola","eslom")...I try to plot the model with this predictor in sequence loop...., for(i in 1:3){ png(paste("fig_",i,sep="")) plot(preplot.gam(mod9)[[i]],se=T,rug=F,main="",xaxt="n",ylab="",xlab="")

Should I be able to use axis() on a barplot? i have a data.frame, the first 3 values of which are: > c[1:3,] median mean A1 56.5 58.50000 A61 73.0 73.00000 A62 63.0 63.00000 > str(c) `data.frame': 19 obs. of 2 variables: $ median: num 56.5 73 63 161 51 55 44.5 22 54 49 ... $ mean : num 58.5 73.0 63.0 161.0 47.5 ... if I do barplot(median) and then try

Hi all, for example: > X<- rnorm(1000) > X0 <- 0.899 I want to draw a density distribution plot with a arrow pointer indicating the position of X0, meanwhile, giving out the p-value. any functions? Thanks very much.

I'm trying something that I thought would be pretty simple, but it's proving quite frustrating... I want to display, for instance, the correlation coefficient "rho" in a graph. I can do something like: text(x, y, paste("rho =", cor)) where cor would be my previously calculated correlation coefficient, and x and y the coordinates. Obviously that displays

Hi, I would like to recommend a minor modification in axis() which I believe can simplify the making of plots for publications. I am trying to define default values for par() in order to make labels bigger and lines thicker, so that the resulting plots look good when resized for publication purposes. I ran into the following problem... axis() does not use par() values as default for

Hi all, To my knowledge, the current version of contour.default() does not handle the 'asp' parameter. This can be embarassing when displaying eg geographical maps, etc... Submitted to the opinion of more experienced R programmers, contour.defaut() function should be changed according to the followings: line 7: add = FALSE,asp=NA,...) line 33: plot.window(xlim, ylim,

Hello, I'd like to add labels to my plot that include a male or female symbol as subscript. I'm working in Windows Vista and R 3.0.0. I am able to add the male symbol to the plot as regular text (NOT as subscript), e.g. with: mtext("Male\u2642") This displays the word "Male" followed by the male symbol on the plot. But "\u2642" does not work when I try to
