Full Discussion: Match first two columns and average third from multiple files

[QUOTE=Scrutinizer;302933668]Try this modification:

Any awk:
Code:
awk '{v=$NF; sub(/ +[^ ]*$/,x); A[$0]+=v; C[$0]++} END{for(i in A) printf "%s%7.1f\n",i,A[i]/C[i]}' file1 file2




Turns out that the above code did not work for me, at least in the way that I am using it.

I have the following script set up:

Code:
foreach numb (`seq 1 100`)
awk '{array[$1 $2]+=$3; a[$1 $2]++} END { for (i in array) {print i, array[i]/(a[i])}}' /dir/of/data/${numb}02.pnt > output.txt
end

I expect the code to search through each of the 100 files and when the first 2 columns match, average the 3rd.

Input File 102:
Code:
43.1042	-78.6042	-6.07
25.2708	-81.1458	19.27

Input File 202:
Code:
43.1042	-78.6042	-4.88
25.2708	-81.1458	17.76


Output:
Code:
43.1042	-78.6042   -5.5
25.2708	-81.1458	18.52

Any suggestions are appreciated!

locale::codes::langfam

Locale::Codes::LangFam(3)				User Contributed Perl Documentation				 Locale::Codes::LangFam(3)

NAME

       Locale::Codes::LangFam - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a
       constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
