R help - Nov 2011 - skip on error

Dear all,
I have a different data sets and I am doing some calculations over time,

For that every data set is split into junks based on the time stamps
so one data set has like 10 timestamps.

There is also the case that one data set has less than 10 timestamps.

In my code I was doing the following

lapply(Datasource,analysis_for_one_data_source)

lapply(TimeFrames,analysis_for_one_data_source_and_one_time_frame)

as you can imagine there are times where the second lapply will
"explode"


analysis_for_one_data_source_and_one_time_frame<- function( DataSource,
TimeFrame,) {
        return( do_analysis(DataSource,TimeFrame))
        
}

as you can understand this will return an error for a given Datasource that does
not have a timestamp. I was looking though if I can ask from R to handle the
error by continuing to the next one. So the lapply that returns and error can
for example to store the error message to the list it returns and continue to
the next element of the lapply list

Would that be possible in R?
B.R
