I would assume that if the code were as follows that the error could the

metatrials<-function(mydata){

colnames(a)=c("sens", "spec", "corr", "sens_se", "spec_se")

here is the error:

gives me back a matrix with as many rows are there are simulations (z) in

It would help if you told us what type of error you are getting and to also
provide sample data so that we could run it to see what happens. I use
'try' a lot to catch errors and have not had any problems with it.

Hi All,
I have tried every fix on my try or tryCatch that I have found on the
internet, but so far have not been able to get my R code to continue with
the "for loop" after the lmer model results in an error.
Here is two attemps of my code, the input is a 3D array file, but really

Jim,
Thanks. Actually I just got it working a few minutes ago with:
tryCatch({download.file(url, destfile = file, quiet = FALSE, mode =
"wb")}, silent = FALSE, condition = function(err) { } )
but I like your suggestion better. I'll attempt to log the list of
url's downloaded ok and those which e
I think this is closer to what you want. You can determine what you
want to do; this one just goes to the next iteration:
date <- as.POSIXlt(as.Date("2007-10-15", "%Y-%m-%d"))
for (i in 1:difftime(as.POSIXlt(as.Date("2007-10-15",
"%Y-%m-%d")),"2007-10-01"))
{
if (date$wday != 0 & da
I am trying to download a bunch of files from a server, for which I am
using download.file( ) within a for loop. The script is working fine
except until download.file hits a URL which has no file, at which
point it exits. I want to change this behavior to simple log the
failure and maintain state w
