TryCatch() with read.csv("http://...")
Hi, folks!
I'm trying to pull in data using read.csv("my URL goes here"), and it really
works fantastically. Amazing to pull in live data right off the internet,
into RAM, and get busy...
however...
occasionally there is a server problem, or the data are not up yet, and
instead of pushing through a nice CSV file, the server sends a 404 "Not
Found" page...

Problem concerning withRestarts and R2WinBUGS
Dear R-users,
I have a question regarding the withRestarts function in R. I´m running a simulation code in which I analyse data using both lme and R2WinBUGS. Now, I want to run this code for 1000 replications, however the model I´m using is a little ´sensitive´, so sometimes the WinBUGS analysis crashes. In that case I want the code to ignore the current results, and redo all steps. This means

suppress *specific* warnings?
Not desperately important, but nice to have and possibly of use to
others, is the ability to suppress specific warnings rather than
suppressing warnings indiscriminately. I often know of a specific
warning that I want to ignore (because I know that's it's a false
positive/ignorable), but the current design of suppressWarnings() forces
me to ignore *any* warnings coming from the

How to catch both warnings and errors?
Dear expeRts,
I am struggling with warning/error handling.
I would like to call a function which can produce either
a) normal output
b) a warning
c) an error
Since the function is called several (thousand) times in a loop, I would like
to proceed "quietly" and collect the warnings and errors [to deal with them at a
later point].
I have seen constructs with tryCatch (which can

GAM (mgcv) warning: matrix not positive definite
Dear list,
I fitted the same GAM model using directly the function gam(mgcv) ... then
as a parameter of another function that capture the warnings messages (see
below).
In the first case, there is no warning message printed, but in the last
one, the function find two warning messages stating "matrix not positive
definite"
So my question is: Do I have to worry about those warnings and

Using IDs to suppress specific messages and warnings
The suppressMessages and suppressWarnings functions currently suppress
all the message or warnings that are generated by the input
expression.
The ability to suppress only specific messages or warnings is
sometimes useful, particularly for cases like file import where there
are lots of things that can go wrong.
Suppressing only messages that match a regular expression has rightly
been rejected

stopifnot
My points:
- The 'withCallingHandlers' construct that is used in current 'stopifnot' code has no effect. Without it, the warning message is the same. The overridden warning is not raised. The original warning stays.
- Overriding call in error and warning to 'cl.i' doesn't always give better outcome. The original call may be "narrower" than 'cl.i'.

"try"ing to understand condition handling
I'm confused by the page documenting tryCatch and friends.
I think it describes 3 separate mechanisms: tryCatch (in which control
returns to the invoking tryCatch), withCallHandlers (in which control
goes up to the calling handler/s but then continues from the point at
which signalCondition() was invoked), and withRestarts (I can't tell
where control ends up).
For tryCatch the docs say

Strange error messages from parallel::mcparallel family under 3.6.0
Dear All,
Since upgrading to 3.6.0, I've been getting a strange error messages

re-throwing an interrupt condition
Anyone knows a way to re-throw a caught interrupt condition, so that
it behaves just like the original one? I.e. no error message is
printed, but the execution is stopped of course. With just calling
stop in the error handler, it prints the error message, or, if there
is no error message (like in the original interrupt condition),
another error happens.
tryCatch(Sys.sleep(100), interrupt =

re-throwing an interrupt condition
The internal code does more or less
signalCondition(e) ## allows for (another) handler
cat("\n") ## cleans up console
invokeRestart("abort") ## jump to 'abort' restart if not handled
[for back compatibility it also runs the error option code if that is
set, but that may go away eventually].

Resume processing after warning handler.
Dear list!
I have a script that processes a large number of data files. When one
file fails to process correctly, I want the script to write a message
and to continue with the next file. I achieved this with tryCatch:

introspective capabilities
Hi,
Is there any way, from R code, to perform introspection as to where
certain names acquired their values? The specific functionality I'm
looking for in this case is to be able to request my editor to view the
definition corresponding to a name in its original source location
(presuming for the moment that that location exists). Other
functionality that I'm looking for is to identify
