Dear all
I have a data.frame like that :
father mother num_daughter daughter
291 3906 0 NULL
275 4219 0 NULL
273 4236 1 49410
281 4163 1 49408
274 4226 1 49406
295 3869 2 49403
49404
287 4113 0 NULL
295 3871 1 49401
292 3895 4 49396
49397
49398
49399
291 3900 3 49392
How to read it into R and transform it like that:
father mother num_daughter daughter1 daughter2 daughter3 daughter4
291 3906 0 NULL
275 4219 0 NULL
273 4236 1 49410
281 4163 1 49408
274 4226 1 49406
295 3869 2 49403 49404
287 4113 0 NULL
295 3871 1 49401
292 3895 4 49396 49397 49398 49399
291 3900 3 49392
library (plyr) and library (reshape2) and other good packages are OK for me.
Thanks a lot!
