Hello,

Please don't post datasets like this, it's unusable by us. Use dput().

?dput
dput(head(myData, 20))  # post the output of this.


Paste the output of that command in a post. It starts with 'structure'. Don't worry if it looks awkward, it is, on the contrary, very usefull. All we need to do s to paste it n an R session to have an exact copy of your data, dat <- structure(...etc...).

Hope this helps,

Rui Barradas

Hi Everyone,
    I could use help developing a for loop. I have a dataset with tallies for
a number of species within 7 different size classes. I need to uncollate the
data into the rawest form (ie: each row a different individual) & retrain
the metadata associated with each row (Date, Recorder, Site, Transect and
Species). Here is an example of the current format:

Could someone help me write a for loop? I am looking for something like this
(represents just the top 2 rows of the first table):

Date  Recorder  Site Transect  SpeciesSize Class
7/6/10  CSC     Puako   A       MOCA    5-10cm
7/6/10  CSC     Puako   A       MOCA    5-10cm
7/6/10  CSC     Puako   A       MOCA    20-40cm
7/6/10  CSC     Puako   A       MOPA    <5cm
7/6/10  CSC     Puako   A       MOPA    <5cm
7/6/10  CSC     Puako   A       MOPA    5-10cm
7/6/10  CSC     Puako   A       MOPA    10-20cm





Many Thanks!
Courtney
