Retrieve parsing problems


vroom will only fail to parse a file if the file is invalid in a way that is unrecoverable. However there are a number of non-fatal problems that you might want to know about. You can retrieve a data frame of these problems with this function.


problems(x = .Last.value, lazy = FALSE)



A data frame from vroom::vroom().


If TRUE, just the problems found so far are returned. If FALSE (the default) the lazy data is first read completely and all problems are returned.


A data frame with one row for each problem and four columns:

  • row,col - Row and column number that caused the problem, referencing the original input

  • expected - What vroom expected to find

  • actual - What it actually found

  • file - The file with the problem
