Subplot positioning

Question

I have a csv file with x, y data and x,y location columns. i.e.

Test,Xloc,Yloc,X,Y
1,1,1,1,1
1,1,1,2,2
1,1,1,3,3
1,1,1,4,4
2,4,4,1,1
2,4,4,2,2
2,4,4,3,3
2,4,4,4,4

Assuming the subplot is 4x4 how could I put a line plot at the 1,1 location for test 1, and the 4,4 location for test 2?

I have ggplot2, and ggsubplot packages installed. Seems maybe it's facet_grid, but not sure and not finding o good examples. Basically there is going to be areas on the figure where there is no subplot.

So this is the data you want to plot? How do you plan to use subplot with this? Can you give some idea what the output will be? — MrFlick, May 30 '14 at 04:39
Not the data I want to plot, but you have to start small. The file I am using has over 1 million lines. I am going to pull the X,Y values from specific tests given a criteria and then plot those all onto one figure depending on their XY locations contained in the csv file. I can read the file and get all the data I want no problem. The best pic I have found that is somewhat similar is here http://revolution-computing.typepad.com/.a/6a010534b1db25970b0177448319ad970d-pi Mine would be line plots not bar plots. In python I used subplot2grid to accomplish this. — user3646105, May 30 '14 at 04:56
Even in that picture though not really what I will do. I want each plot to have it's own X and Y axis values to show for each sub plot. — user3646105, May 30 '14 at 05:00
It's best to edit your original question rather than adding info in comments. It can be more neatly organized that way. I must admit i'm still having a hard time understanding this because it's abstract. See the guide on [how to create reproducible examples](http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) for ideas about building sample data sets to illustrate your point. Please don't post 1 million lines, just enough to get the idea of what you want. — MrFlick, May 30 '14 at 05:04
This python plot is closer to what I want to do http://matplotlib.org/users/tight_layout_guide-5.png but what I am plotting is tested over a circular pattern, so the sub plots would be laid out in a circular fasion. Basically trying to see if issues exist on certain areas of the surface tested. — user3646105, May 30 '14 at 05:13

Is this is what you are trying to achieve?

temp <- read.csv(text = "
Test,Xloc,Yloc,X,Y
1,1,1,1,1
1,1,1,2,2
1,1,1,3,3
1,1,1,4,4
2,4,4,1,1
2,4,4,2,2
2,4,4,3,3
2,4,4,4,4")

library(ggplot2)
ggplot(temp, aes(X, Y)) + geom_line() + facet_wrap(~ Test, scales = "free")
