So I have a text file that looks like this:
"Label" "X" "Y" "Slice"
1 "Field_1_R3D_D3D_PRJ_w617.tif" 348 506 1
2 "Field_1_R3D_D3D_PRJ_w617.tif" 359 505 1
3 "Field_1_R3D_D3D_PRJ_w617.tif" 356 524 1
4 "Field_1_R3D_D3D_PRJ_w617.tif" 2 0 1
5 "Field_1_R3D_D3D_PRJ_w617.tif" 412 872 1
6 "Field_1_R3D_D3D_PRJ_w617.tif" 422 863 1
7 "Field_1_R3D_D3D_PRJ_w617.tif" 429 858 1
8 "Field_1_R3D_D3D_PRJ_w617.tif" 429 880 1
9 "Field_1_R3D_D3D_PRJ_w617.tif" 437 865 1
10 "Field_1_R3D_D3D_PRJ_w617.tif" 447 855 1
11 "Field_1_R3D_D3D_PRJ_w617.tif" 450 868 1
12 "Field_1_R3D_D3D_PRJ_w617.tif" 447 875 1
13 "Field_1_R3D_D3D_PRJ_w617.tif" 439 885 1
14 "Field_1_R3D_D3D_PRJ_w617.tif" 2 8 1
What it represents are the locations of centromeres per nucleus in a
microscope image. What I need to do is do a dist() on each grouping (the
grouping being separated by the low values of x and y's) and then compute an
average. The part that I'm having trouble with is writing code that will
allow R to separate these objects. Do I have to find some way of creating
separate data frames for each object? Or is there a way to parse the file
and generate a single data frame of all the pairwise distances? Any
suggestions or example code would be much appreciated. Thanks!
