ReplyDeletecan some one please explain why it is D
ReplyDeletethanks
with DSD option two consecutive delimiters are not consider as one, so missing value is assigned to item2 and as item2 is character variable it has missing character value " ". Without DSD Item2 will be table. Hopefully that helps.
ReplyDeletehi..without dsd it should be error...
ReplyDeleteyes.without dsd it will be error.else you should use dlm=',' option.then consecutive commas will be considered as one.the dataset will have only one observation.for the second reord it will go past the record.
