catch error/warning message in a loop
With situations like this, I often include something like "cat(i, '')" in the loop (where "i" is the index of the loop). If I'm writing a function to be used by others, I might use "try", as described, e.g. in Venables and Ripley (2000) S Programming (p. 48). hth. spencer graves

Hi, I am running cox regreesion (coxph) on a large number of independent variables, one variable at a time, using loop. At some point of the loop, the cox regression stopped due to some errors. How can I know at which variable the cox regression stopped so that I can pinpoint the variable that causes the problem? I guess this is not unique to cox regression, it is the problem of catching the error/warning message promptly in a loop. tahnks
