Dear R-ers,
I was trying to read in a large sas7bdat file (size 148094976 bytes) using
'read.sas7bdat()', but it did not read in the data correctly. E.g., the first
5 rows will come out like this (I'm omitting other columns to keep it readable):
PERSON_ID age
1 5.399114e-315 5.329436e-315
2 5.399114e-315 5.328302e-315
3 5.399114e-315 5.332026e-315
4 5.399114e-315 5.329112e-315
5 5.399114e-315 5.331055e-315
If I reduced the original sas dataset to the first 5 rows, 'read.sas7bdat' read
them in correctly:
PERSON_ID age
1 612569 55
2 612571 48
3 612580 78
4 612606 53
5 612617 66
So for now I first saved the sas dataset as .csv, then read using 'read.csv',
everything is fine.
Any suggestion why 'read.sas7bdat' didn't work, and if some fix in its code can
make it work?
Thank you.
