Dear list,
I am running R in slave mode to run some calculations on a remote cluster and
would like to somehow retrieve the last command in the case that it causes an
error. When an error occours, my job is just quitted and it takes me a lot of
work to find out which command in my rather lengthy scripts caused the problem.
With the following I manage to save the workspace in case of an error:
save.ws.error = function()
{
last.error <- paste('Last error: ',geterrmessage(),sep='')
save.image(file='filename.RData')
}
options(error=quote({save.ws.error()}))
I would like to include
history() or savehistory() in this call to get the command that caused the
error but when I run my script with:
R --slave < scriptname.R > text_output.out
i get the error message that there is no command history available.
Is there any way to achieve this?
Cheers
Jannis
