Hi Laurent,
Sorry to trouble you again. I have little idea how to get R to know if a warning has taken place. I tried using last.warning as I think it was what you suggested. But still track.warning is NULL although there are warnings. The code goes something like this:
w1<-0 track.warning<-NULL .... if(length(last.warning)>w1){ track.warning<-c(track.warning,data.no) }
It seems to me that length(last.warning)==0 throughout the running of the program although in the end there are still errors.
Please advice. Thanks for your help.

Hi Laurent,
Thanks for the suggestion. However I am not too sure how to access
this last.warning while in the loop. From my understanding, I can't get dimensions from a list.
l <- list(a=1:2, b=letters[1:5]) length(l) lapply(l, length)
...if it answers your question....
Please advice.

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.

One way to do things is to have a list to store warnings has you hit them in you loop: you can access what is the list last.warning.
Hopin' it helps,
