Tue, 5 Aug 1997 17:00:03 +1200 (NZST)
A set of patches for R-0.50-a1 is now available as
The patches mainly fix problems reported since R-0.50-a1 but some
older problems are also fixed.
Here is the list of changes.
o Many subsetting and mutation problems with the new "expression" type
have now been fixed.
o When ask=T is set in par() the user is instructed
"Press <Return> for next plot:"
rather than asked
o The infinite recursion observed by in Kurt Hornik in:
attr(x, "call") <- sys.call()
Error: stack overflow
has been cured. There may be one or two more of these. All the
xxxx<- functions should be checked.
o Patches from Benjamin Bolker to cure some line type problems has
o Fixed the t(table(0)) problem (1-d arrays not quite handled right).
o Changed naming back so that pow_dd etc are available.
o Patches to barplot and text from Kurt Hornik.
o When x was a data frame,
mode(x) <- "character"
caused a crash. This was because a class of "data.frame"
was being attached to a character vector. Now only lists
can become data frames.
o There is now a -gdb option to the R front end as well as -xxgdb.
o Documentation of NChisquare fixed.
o Definition of S_alloc fixed.
o Changed the names of seeds_in and seeds_out to seed_in and
seed_out as per Kurt's request.
o "unlist(c(2))" fixed.
o "data.frame(x=2)" fixed.
o Bug in do_title fixed.
o Scoping for subset methods by forcing an eval of the args on
entry fixed (bug reported by Patric Lindsay).
o subsetting of data frames fixed .
o Misc problems in Rdoc.sty reported by Kurt Hornik fixed.
o Permissions in the data subdir for quakes and sunspots fixed.
o Segfault in dimnames mutation
R> x <- 1:5
R> dimnames(x)[1,2] <- NULL
o It was observed that
> D(expression(z * (log(z) /z)), "z")
(log(z)/z) + z * (1/z/z - log(z)/z^2)
This is exactly what S-Pus produces.
o Added the option -B 8192 to m4 in the etc/doc2* files to keep
o New functions "as.ordered", "data.class" and "scale" from, Kurt
