Where do you see that?
The sources have
\item \command{R CMD check} has a new option \option{--as-cran} to
turn on most of the customizations that CRAN uses for its incoming
checks.
but there has been issues with LaTeX converting "--" to en-dash. (We saw it
with the style files used for The R Journal, but that is hardly the case this
time.)

[Rd] missing value break my if clause and crash my program
I have a program which is designed to read through a dbf file and carry out certain amount of further calculation if one condition obtained from the newly read line. The condition to determine if the calculation can be done is a if-clasue (i.e. if(m>0). Unfortunately, when m is missing, the program crashed. Just wonder who can help me out.

[Rd] Replace back slashes with forward slashes?
Hello, All:
What can people tell me about converting back slashes to forward
slashes in character strings?
Several years ago, Prof. Ripley provided a solution, which I lost
and have not been able to find.
Below please find a function to do this. I do not find this very
satisfactory, however, because it uses "scan" and therefore operates on
an input not a character string. Unless someone suggests something
better, I plan to add this to the "sos" package and issue a new release
very soon. (The new release is needed, because the RSiteSearch
capability has been modified in a way that breaks the current "findFn"
core of "sos".)
Thanks,
Spencer
back2forwardslash <- function (nmax = 1, pattern = "\\", replacement =
"/") {
x <- scan(what = character(), quote = pattern, nmax = nmax)
x. <- gsub(pattern, replacement, x, fixed = TRUE)
paste(x., collapse = " ")
}
(x <- back2forwardslash())
c:\Users\
# nmax must be one more than the number of embedded blanks
(x3 <- back2forwardslash(3))
c:\u\a b\c d

That's it's trivially done with
gsub("\\", "/", x, fixed=TRUE)
Where x is the character string (and I suppose you are aware of it since you
are using it below).
The rest of this e-mail makes absolutely no sense to me -- what exactly are you
taking about? What else do you want to achieve?

It does not work for me. Consider the following:

This is one reason I needed to use "scan". Even if I could get

[1] "\t"
It seems far from trivial, which is why I wrote this function and
am looking for a better one.
Thanks for the reply.

This is something your editor could do much better than R.

But that has nothing to do with strings - it is an user error since you are not
creating a valid string in R (not that backslash needs to be escaped in R --
just like in C and many other languages). You probably meant to write
> x <- "c:\\users\\"
> cat(x,"\n")
c:\users\
> gsub("\\","/",x,fixed=TRUE)
[1] "c:/users/"

[Rd] Alternative to .Internal(.dfltStop(msg, call))?
Hi,
I'm looking for a way to generate a "full stop" that will not be
caught by signal handlers, cf. .Internal(.dfltStop(msg, call)).
RATIONALE:
In the R.oo package I have throw() which (leaving out some details)
basically does what stop() does but appends a stack trace string to
the error message that shows up at the R prompt. Example:
bar <- function() throw("A foo error");
foo <- function() bar();
> foo()
Error: A foo error
at foo()
at bar()
versus
bar <- function() stop("A foo error");
foo <- function() bar();
> stop("A foo error")
Error: A foo error
CURRENT SOLUTION:
throw() does this in a way such that the stack trace is *not* part of
the getMessage() of the 'error' condition object, which is important
when catching the error in signal handlers. Here is a stub what is
done, leaving out the details how to retrieve the stack trace (call
history):
throw <- function(msg, ...) {
cond <- simpleError(msg);
signalCondition(cond);
# A dummy stracktrack / call history
stackTraceStr <- "at foo()\nat bar()\n";
call <- NULL; # Also a dummy for this example
# If the condition is not caught, do a "full stop" showing error
message and stacktrace
fullmsg <- paste(msg, "\n", stackTraceStr, sep="");
.Internal(.dfltStop(fullmsg, call));
} # throw()
QUESTION:
Is it possible to achieve this without using an .Internal() call?
Note that stop() will use the same message string for both
signalCondition() and .Internal(.dfltStop(...)), cf.
> base::stop
function (..., call. = TRUE, domain = NULL)
{
...
message <- conditionMessage(cond)
call <- conditionCall(cond)
.Internal(.signalCondition(cond, message, call))
.Internal(.dfltStop(message, call))
...
}
ALTERNATIVE?:
Is there an alternative way to have the stack trace/traceback() being
automatically displayed after the error message being displayed at the
prompt?
