How to average the third column for each value of the first column?
So I have a large amount of comma delimited data that looks like this:
I need to change this data such that the third column is averaged for each different value of the first column. So I would have something like this:
So for each unique value in the first column the third column is averaged. (only the first column matters because there are no two rows in my data with the same first column but different second columns0
I have tried numerous awk and Perl solutions to similar problems online. I am stumped.
If someone could point me in the right direction that would be incredible.

Hi I have fakebook.csv as following:

Hi, I tried to do this in excel but there is a limit to how many rows it can handle.
All I need to do is average each column in a file and get the final value.
My file looks something like this (obviously a lot larger):
Joe HHR + 1 2 3 4 5 6 7 8
Jor HHR - 1 2 3 4 5 6 7 8
the output... (1 Reply)
Dear All,
I have this file tab delimited
A 1 12 22
B 3 34 33
C 55 9 32
A 12 81 71
D 11 1 66
E 455 4 2
B 89 4 3
I would like to make the average every column where the first column is the same, for example,
A 6,5 46,5 46,5
B 46,0 19,0 18,0
C 55,0 9,0 32,0
D 11,0 1,0 66,0... (8 Replies)
Hi,
I would like to calculate the average of column 'y' based on the value of column 'pos'.
For example, here is file1
id pos y c
11 1 220 aa
11 4333 207 f
11 5333 112 ee
11 11116 305 e
11 11117 310 r
11 22228 781 gg

Hi,
I am searching for an awk-script that computes the mean values for the $2 column, but addicted to the values in the $1 column. It also should delete the unnecessary lines after computing...
An example (for some reason I cant use the code tag button):
cat list.txt
1 10
1 30
1 20... (2 Replies)
I have a file that looks like this:
id window BV
1 1 0.5
1 2 0.2
1 3 0.1
2 1 0.5
2 2 0.1
2 3 0.2
3 1 0.4
3 2 0.6
3 3 0.8
Using awk, how would I get the average BV for window 1? Output like this:
window avgBV
1 0.47
2 0.23 (10 Replies)
Hi,
My input file
Gene1 1
Gene1 2
Gene1 3
Gene1 0
Gene2 0
Gene2 0
Gene2 4
Gene2 8
Gene3 9
Gene3 9
Gene4 0
Condition:
If the first column matches, then look in the second column. If there is a value of zero in the second column, then don't consider that record while averaging.

Hi all,
Does anyone know of an efficient unix script to average each numeric column of a multi-column tab delimited file (with header) with some character columns.
Here is an example input file:

set_color
set_color(1) fish set_color(1)NAME
set_color - set_color - set the terminal color
set_color - set the terminal color
Synopsis
set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]
Description
Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
cyan, white and normal.
o -b, --background Set the background color
o -c, --print-colors Prints a list of all valid color names
o -h, --help Display help message and exit
o -o, --bold Set bold or extra bright mode
o -u, --underline Set underlined mode
o -v, --version Display version and exit
Calling set_color normal will set the terminal color to whatever is the default color of the terminal.
Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
font color, while set_color --bold white will result in a white font color.
Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.
set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
ncurses and recompile fish against it in order to fix this issue.
