Hi All,
Please help me in the below code:
tryCatch({
x <- capture.output(XML::xmlParse(y))
}, warning = function(w) {
x <- capture.output(w)
}, error = function(e) {
x <-capture.output(e)
}, finally = {
})
I am using Tibco Enterprise Runtime for R to get value of the parsed XML in
vector f
I want to use tryCatch, but tryCatch seems to obscure important things I
need for debugging.
For example, say I am working with an SQLite database, and have written
this function:
debugThisFunction <- function(dbfile) {
require(RSQLite)
drv <- SQLite()
conn <- dbConnect(drv, dbfile)
tryCa
Hi,
Suppose we have a general function that returns a logical indicating
which values in 'x' are found in 'l', throwing an error if none are
found and a warning if only some are found:
"checkFun" <- function(l, x)
{
xinl <- x %in% l
if (! any(xinl)) stop("none of the x values found in l")

I am trying to compute the approximate numerical integration of the following
expression using the integrate function:

Error in integrate(function(x) { : the integral is probably divergent
which gives me an error. If

Start with try(): you may find it easier to understand.
if(inherits(try(), "try-error"))
so in your case
if(inherits(try(sqlSave(pg, tbl[i, ], "tbl", append = TRUE,
rownames = FALSE
sqlUpdate(pg, tbl[i, ], index = "key")
or some such.

I would like to do inserts into a database table, but do updates in the fairly
rare cases in which the inserts fail. I thought tryCatch might be the way to do
it, but I honestly do not understand the help file for tryCatch at all.
I thought something like this might work:
for (i in seq(along = t

Dear all,
I am not sure I understand fully the functionality of "tryCatch" and
"try" commands and how these are used to continue a for/next loop if an
error occurs within the loop.
Can somebody point me to material (or share some code) with more
extensive examples than the ones in the help/F
Dear R-group,
I am looking for some good examples on trycatch. Any pointers?
The help manual seems quite limited.
Thanks.

Hi there,
I have a nested call of lapply in which I do a tryCatch statement like this
lapply(1:length(p_names), function(w_idx) {
r <- as.numeric(pos_r[[w_idx]][1])
c <- as.numeric(pos_c[[w_idx]][1])
pos <- c(r,c)

Hi All R-Gurus,
I am trying to debug a program, and I think tryCatch will help. The functions
involved
process through so many times before I encounter the error, things are a bit
slow to
use debug and browser().
I've read the help file and postings on conditions, and am still having trouble

I would like to use the 'tryCatch' function but am having a hard time getting
my head around it. In 'C' like languages try/catch/finally means try a block of
statements and if any throw an error then do the statements in the catch block
and then error or not always do the staements in the finall
Can you provide an example of what you have tried. This should work:
for(i in 1:4){
x <- try(yourFunction(...))
if (class(x) = "try-error") print('had a problem")
}

Dear helpers,
I've got a main script, which calls 4 times a function on 4 different
datasets respectively. This function runs "nls" and is located in
another R script which is sourced into my main script.
What I would like to have is this:
If, e.g. in the 3rd call of the function, nls fails, bec
