This function performs all relevant checks to assess if a GADSdat complies with all of
Stata's dataset requirements. Run this before exporting a dataset as .dta, using
write_stata.
Usage
check4Stata(GADSdat, version = c("Stata", "Stata 19/BE", "Stata 19/MP"))Value
Either NULL if all checks are passed successfully, or a list of all
check results (see details for explanations of the keywords) if any problem was detected.
Details
Specifically, the following requirements are tested:
dots_in_varNames* | Variable names do not contain dots (checkVarNames). |
special_chars_in_varNames* | Variable names do not contain special characters. |
varName_length* | Variable names are not longer than the specific limit (checkVarNames). |
labeled_fractionals* | There are no labeled fractional values (checkLabeledFractionals). |
large_integers* | All labeled values can be coerced as.integer (checkIntOverflow). |
varLabel_length | Variable labels are not longer than the specific limit (checkVarLabels). |
valLabel_length | Value labels are not longer than the specific limit (checkValLabels). |
long_strings | String variables do not contain string values that are longer than the specific limit. |
too_many_rows* | The number of rows/observations does not exceed the specific limit. |
too_many_cols* | The number of columns/variables does not exceed the specific limit. |
Not complying with the marked (*) requirements will prevent a dataset from being exported to a
.dta file. Issues with unmarked requirements will be solved automatically by truncating.
Limits to different aspects of the dataset vary between versions of the software. By default
(version = "Stata"), compliance with the limits for Stata 19/SE is checked.
Checks against the limits for Stata 19/BE or Stata 19/MP can be requested by
specifying version with the corresponding string. For more details, see program_limits.
