There is still issues with the reversed y-log scale plot: # Test case A: works as expected plot(10:100,log="y",ylim=c(100,11)) grid() par("yaxp") # Test case B: grid does not have horizontal lines; par("yaxp") is different plot(1:100,log="y",ylim=c(100,10)) grid() par("yaxp") In the second test case, axTicks for the horizontal lines (in

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")

The "New Bug Report" form available from http://bugs.r-project.org/ appears to double encode the HTML of the "body" text area of the form. This behaviour can be seen in submission ID # 11515, where (as an example) "??" is converted to "&#916;" in the browser view or "&amp;#916;" in the HTML source code. Conversion to

Full_Name: Michael Toews Version: 2.7.0 OS: Windows XP SP2 Submission from: (NULL) (24.80.163.230) Using Unicode characters in Windows works with static strings (as of R 2.7.0), however fails when used with sprintf() or paste(). For example, on R 2.7.0 for Windows XP (SP2): Static string (works, showing Greek Delta character): > print("\u0394Q = 2.2 L/s") [1] "&#916;Q =

In the latest R 2.8 alpha for Win32, if either of the commands are typed: > help("erfc") .. or .. > ?erfc the result is: No documentation for 'erfc' in specified packages and libraries: you could try '??erfc' This should be: 'help.search("erfc")', as shown in R 2.7.2 Apologies if this has already been submitted/fixed. -Mike --please do not edit

Full_Name: Michael Toews Version: 2.3.1 OS: Mac OS 10.4.6 and WinXP/SP2 Submission from: (NULL) (24.80.163.133) This bug also affects related functions (write.csv, etc.), and can be demonstrated using either a matrix or data frame: m <- matrix(1:9,nrow=3, dimnames=list(c("A","B","C"), c("I","II","III")))

Full_Name: Michael Toews Version: 2.3.1 OS: WindowsXP Home/Proffesional SP2 Submission from: (NULL) (142.58.206.114) Hi, I have a bug that I can reproduce on two different MS Windows platforms (1:AMD64x2/WinXP SP2 Home; 2:P4/WinXP SP2 Prof.) which is triggered by the "Save as" dialog when saving a plot from a Windows device onto the Desktop. This bug is difficult to reproduce, but here

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 <-

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

Full_Name: Michael Toews Version: R-devel and 2.4.1 OS: Debian etch and WindowsXP Submission from: (NULL) (142.58.206.114) This is a quick demonstration of the present time limitation of 'sprintf' on long vectors with a suggestion for significant optimization. First, consider a data.frame with numeric (double) values: dat <- data.frame(year=as.numeric(rep(1970:2000,each=365)),

Full_Name: Michael Toews Version: 2.61 OS: WinXP SP2 Submission from: (NULL) (142.58.206.114) Using boxplot on a PDF device with more than one group (or boxes) produces multiple (and overlain) 1st and 3rd quartile ticks. There are exactly the multiple of boxplot groups as there are of each 1st and 3rd quartile ticks for each boxplot (drawn as a horizontal line at the end of each boxplot), which

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, Me and an office colleague on Microsoft Windows 10 PCs are having difficulty installing any package. This is a recent issue for us, and we suspect our McAfee antivirus has modified by our IT department. Let's take, for example, install.packages("mypackage"), here is the output: package ?mypackage? successfully unpacked and MD5 sums checked Warning in install.packages : unable

I consider this to be an old bug, which also persists in Splus 7. It is unnecessary, and annoying. ## Section 1: Consider a simple data frame with three possible factors (in levels) d <- data.frame(a=sort(rnorm(10)*10), b=factor(c(rep("A",4), rep("C", 6)), levels=c("A","B","C"))) tapply(d$a, d$b, mean) # returns three results, which I

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
