Re: [R] try-error within for loop

Assigning the value directly to result[i] would give a null to result. Like that: result[[i]]<-taxondiveO(abd,taxa) result[[i]]<-as.data.frame(result[[i]])[1,] In fact your code's result should have null elements in it. You lost your nulls through do.call process. I can't find a way to assign t

[R] try-error within for loop

Dear all, I run a loop wrapped in try(), and for each of the rows where "try-error" is true I want to fill that row with NA (at the moment it is omitted). So I would expect to get a dataframe with 1000 rows some of which would be empty, but instead I get a dataframe with 995 rows. In this case mi
