listMissings | R Documentation |
Missing can be NA and for character variables it can be certain strings too. This function is experimental and design may change in future releases.
listMissings(data, cols, by, na.strings = c("", "."), quiet = FALSE, as.fun)
data |
The data to look into. |
cols |
The columns to look for missings in. |
by |
If supplied, we are keeping track of the missings within the values of the by columns. In summary, by is included too. |
na.strings |
Strings that should be interpreted as missing. All spaces will be removed before we compare to na.strings. The default is c("",".") so say " . " is a missing by default. |
quiet |
Keep quiet? Default is not to. |
as.fun |
A function that will be run on the result before returning. If first input data set is a data.table, the default is to return a data.table, if not the default is to return a data.frame. Use whatever to get what fits in with your workflow. Default can be configured with NMdataConf. |
Invisibly, a data.frame including all findings
