Hi, I have questions about object attributes, and how they are handled when subsetted. My examples will use: tm <- (1:10)/10 ds <- (1:10)^2 attr(tm,"units") <- "sec" attr(ds,"units") <- "cm" dat <- data.frame(tm=tm,ds=ds) attr(dat,"id") <- "test1" When a "primitive class" object (numeric, character, etc.) is

In R 2.5.0 (r40806), one of the change is to allow partial matching of "name" in the attr function. However, how can I tell if I have an exact match or not? For example, checking to see if an object has a "name" attribute, then giving it one if it doesn't: dat <- data.frame(x=1:10,y=rnorm(10)) if(is.null(attr(dat,"name"))) attr(dat,"name")

Hi all, I'm usually comfortable using the *apply functions for vectorizing loops in R. However, my particular problem now is using it in a sequential operation, which uses values evaluated in an offset of the loop vector. Here is my example using a for loop approach: dat <- data.frame(year=rep(1970:1980,each=365),yday=1:365) dat$value <-

Hi, I seem to be unable to get a mixed legend that has lines *or* polygons (not both). For example: ppi <- seq(0,2*pi,length.out=21)[-21] frame() plot.window(ylim=c(-5,5),xlim=c(-5,5),asp=1) polygon(cos(ppi)*4+rnorm(20,sd=.2),sin(ppi)*4+rnorm(20,sd=.2), col="green",border=FALSE) polygon(cos(ppi)*2+rnorm(20,sd=.1),sin(ppi)*2+rnorm(20,sd=.1), col="blue",border=FALSE)

Hi, I have a feature request for 'parse', and possibly the 'R CMD INSTALL' command to display more informative error information. Specifically, after making several modifications to a package on my system (the package name is irrelevant; I'm using R 2.3.1 on Debian): $ R CMD INSTALL seas * Installing *source* package 'seas' ... ** R ** data ** inst ** preparing

Here is a patch to improve documentation for finding useful, yet newish, functions: 'findInterval' and 'colorRamp'. I think that it is worthwhile to mention these in the 'seealso' section of the similar 'match' and 'palette' documents. I had difficulty finding these functions at first, as they have compound names. Modify the patch as needed. +mt
