axTicks on a reverse ylog plot (PR#7973)
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))

par("yaxp")
In the second test case, axTicks for the horizontal lines (in

Object attributes in R
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

exact matching of names in attr
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")

Double HTML encoding in R Bug Tracking Submission form (PR#11517)
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 "Δ" in the browser view or
"&#916;" in the HTML source code. Conversion to

...uppose an additional argument, e.g.,

Then this additional argument can be pass on from boxplot.formula() to
split().

Using unicode with sprintf or paste in Windows (PR#11515)
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):

Bug with message if there is no documentation; R2.8alpha Win32 (PR#13131)
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.

Rgui.exe plot device "Save as" crash (PR#9237)

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

is difficult to reproduce, but here

sequential for loop
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 <-

Documentation patch for 'match' and 'palette'
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.

Feature request for 'sprintf' optimization (PR#9621)
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)),

End of whiskers of boxplots are repeated on PDF device (PR#10499)

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

legend with mixed boxes and lines (not both)
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)

unpackPkgZip: "unable to move temporary installation" due to antivirus
Hi,
Me and an office colleague on Microsoft Windows 10 PCs are having

we suspect our McAfee antivirus has modified by our IT department.
Let's take, for example, install.packages("mypackage"), here is the

I have a feature request for 'parse', and possibly the 'R CMD INSTALL'
