Hi
I did not see any response and actually I can not offer any ready made
solution too. For such problems there could be various solutions from
cycles to *apply, reshape or plyr options.
However for anybody to start with it would be nice to get rather more
clear description together with some small toy ready available data
(preferably produced by dput) and desired result.

Hello,
I have a very large content analysis project, which I've just begun to
collect training data on. I have three coders, who are entering data on
up
to 95 measurements. Traditionally, I've used Excel to check coder
agreement
(e.g., percentage agreement), by lining up each coder's measurements
side-by-side, creating a new column with the results using if
statements.
That is, if (a=b, 1, 0). With this many variables, I am clearly
interested
in something that I don't have to create manually every time I check
percentage agreement for coders.
The data are set up like this:
IDCODER V1 V2 V3 V4 ... V95
ID1 C1 y int doc y
ID2 C1 y ext doc y
ID1 C2nint doc y
ID2 C2nint doc y
ID1 C3 n int doc y
ID2 C3 n int doc y
I would like to write a script to do the following:
For each variable compare each pair of coders using if statements (e.g.,
if
C1.V1.==C1.V2, 1, 0)
IDC1.V1 C2.V1 C3.V1
ID1 y y y
ID2 yy y
For each coding pair, enter the resulting 1s and 0s into a new column.
The new column name would reflect the results of the comparison, such as
C1.C2.V1
I'd ideally like to create this so that it can handle any number of
variables and any number of coders.
I appreciate any thoughts, help, and pointers on this.
Thanks in advance.
Best,
