split nukes names() (PR#371)
> split(c(a=1,b=2),c(1,2))
$"1"
[1] 1
$"2"
[1] 2
The documentation does not *promise* that names will survive, but in
Splus3.4, they do. This broke a function that worked under S+ that used
the names attribute of elements in the components returned by split.

cor(x,y) when is.null(y) (PR#883)
Problem:

I'd prefer a warning() or stop() in that case.
Solution (??) :

NA as names of vector from subscripted matrix == bug ?
Is this a bug?

1 NA

It has some annoying consequences, e.g.

"[.data.frame" allows un-named 3rd subscript (PR#989)
Since the Extract page has usage as:
x[i, j, ... , drop=TRUE]
I would expect that 'drop=' would need to be given to the third 'subscript'
> diag(4)[ , 4 , 4 ] # Forgot 'drop=' or added extra ','

substitute(x$y)) corrupts 'y' component (PR#731)
viz.
> (function(x,y=a) substitute(x$y))(x)
x$a
> (function(x,y=a) substitute(x$y))(list(y=1:3))
list(y = 1:3)$a
> (function(x,y) eval(substitute(substitute(y))))(x=list(y=1:3),y=x$y)
list(y = 1:3)$x$y
The behavior I expect and want is like that in Splus 3.4:
> (function(x,y=a) substitute(x$y))(x)
x$y
> (function(x,y=a) substitute(x$y))(list(y=1:3))
list(y = 1:3)$y

make check fails after base-Ex.R
Dear R-help,
I tried to build the R-release version of R-1.0.0.
./configure and make seemed to go just fine.
When I ran 'make check' from $RHOME, it dumped core apparently in the
quit('no')
on the last line of base-Ex.R
I had been having some problems with a package I am building in that R
would report with "Process R segmentation violation (core dumped)" upon

dimname'less array breaks apply (PR#318)
<<insert bug report here>>
> apply(array(1:20,c(2,2,5)),2:3,function(x) x)
Error: length of dimnames must match that of dims
>
Changing:
dimnames = if (is.null(dn.ans)) list(ans.names, NULL) else c(list(ans.names), dn.ans)
To:
dimnames = if (length(dn)==0) NULL else
if (is.null(dn.ans)) list(ans.names, NULL) else c(list(ans.names), dn.ans)
seems to fix this.

all.equal.list() sometimes fails with unnamed and named components (PR#674)
examples:
1) Fails to report that components 2 and 3 differ
all.equal(list(1,2,3,zap=1),list(1,3,4,zap=2))
[1] "Component zap: Mean relative difference: 1
2) Incorrectly asserts all are equal when components 2 and 3 differ

3) Removing named component reveals differences:

bqtl available on CRAN
Package bqtl version 1.0 is now available on CRAN.
Description: QTL mapping toolkit for inbred crosses and
recombinant inbred lines. Includes maximum likelihood and Bayesian
tools.
I am keen to have comments about this package including implementation
details, additional functionality, and (of course) problems and bugs.

matlines, matpoints don't follow prototype (PR#506)
The Blue Book allows the 'type' argument to be used in matpoints and
matlines.
matlines(x, y, type="l", lty=1:5, pch=, col=1:4)
R-1.0.0 does not.
Thus, type="h", "b", must be invoked thru matplot( x, y, type = "h",
add=TRUE)
For the sake of consistency with S, it would be nice to have matlines
defined as:

unz( "x.zip", "y.csv" ) != pipe( "unzip -p x.zip y.csv" )
Not sure this is a bug in R.
Maybe its a bug in my understanding of unz().
The character 'b2' (hexadecimal) is in position 535 of line 1
of 'naughty.csv'. This character appears as superscript '2' and came to me
in an EXCEL file that I converted to text in a comma separated ( *.csv )
format.
The first line gets truncated by readLines after 534 characters using

rw1020 Rcmd INSTALL path\ deletes rw1020\library\* (PR#789)
The trailing backslash seems to be the culprit.
After looking at rw1020\bin\INSTALL, I noticed
$pkg =~ s/\/$//;
which I assume is to strip the trailing slash from a package name
before obtaining the package name and cleaning out its directory
I added
$pkg =~ s/\\$//;
immediately after this line. Rerunning
Rcmd INSTALL C:\rw1011\src\library\bqtl\
with that change seemed to work OK
