Hi there,
I am interested if there is anyway to keep track of the occurrence of
warning message.
I know that warnings will only be printed out at the end of the program
if warn=0. However I am also interested at which particular set of data
does the warnings occur too. This is because I am running 1000 data, so
if there are 2 or 3 data that give warnings, I would like to know which
are the ones out of the 1000 data.
I tried using the following code in the program to indicate where the
warning occur but was unable to get anything recorded although the
warnings() gave me 12 messages.
track.warning<-NULL
....
if(options("warn")$warn>=0){
track.warning<-c(track.warning,data.no)
}
Your help is greatly appreciated. Thanks.
