Hi Keith,
You do need to reorganize your data. cor() will work on any number of variables
as long as they are columns in a matrix or data frame.
There are a lot of ways to reorganize data, of various power and complexity.
Here's one simple way:

Dear list,
I have 9 repeated measures (measurement variable == 'Delta13C') for
individuals (ID variable == 'Individual_ID'. Each repeated measure is
indexed (right term?) by the variable 'FeatherPosition' and given as
c('P1', 'P2', 'P3', 'P4', 'P5', 'P6', 'P7', 'P8', 'P9'). I would like

Hi Gireesh,
I seem to be missing something.
Could you give me the formula you think should be used to calculate this?
I don't get how you wish to get a correlation for only one pair of
numbers.
(or maybe I didn't understood what you explained - please try a simpler
example)
in one output
x - S1 i.e. 112 with all combinations ex:
112 vs 3 [ x-S1 vs a -S1]
112 vs 4 [ x-S1 vs a- S2 ]
112 vs 45
112 vs 34
112 vs 23
112 vs 112
.
..
112 vs 1
in second output
x - S2 i.e. 0 with all . ex:
0 vs 3
0 vs 4
0 vs 1
in next output
x-S3

Hi there,
I'm not sure I understand your question.
What are the two vectors you wish to check their correlation?
Are they the two rows x and a?
Because from your example it seems you are trying to do a correlation
between two singular numbers (so probably I didn't get something straight).

Dear All,
I have a matrix of size 1 x 50. I would like to calculate all possible
pair-wise correlation coefficient (5x10^7 combinations) using cor(). How can I
efficiently calcualte and save the result in a matrix?
Thanks in advance.
Kind regards,
Ezhil
