Hello,
This is my first attempt at using R. Still trying to figure out and understand
how to work with data frames.
I am trying to plot the following data(example). Some experimental data i am
trying to plot here.
1) i have 2 files
2) First File:
Number Position
1 120
2 134
3 156
4 169
5 203
3) Second File:
Col1 Col2 p-val
1 2 0.45
1 2 0.56
2 3 0.56
2 3 0.68
2 3 0.88
3 4 0.76
3 5 0.79
3 5 0.92
I am trying to plot this with "position" as x-axis and "p-val" as the y-axis.
The col1 and col2 in the second file correspond to the number column in first
file.
I am having trouble to figure out how to associate the col1 and col2 with
their corresponding position values
The x-axis should start with 120 as that is the min value and next values
should be spaced proportionally away from the
first. I tried using the percentage method to place them...but couldnt
completely get it correct.
so it would look like :
| | | | |
120 134 156 169 203
Hopefully i explained it correctly.
i would like to plot the p-value as horizontal lines drawn between the col1
and col2 values (ie: positions)
So, the plot will have as many horizontal lines as the rows in the second file.
And ONE reference horizontal line passing thru the plot at p-val=0.5, to see
what values lie below that and what above it.
I have made some progress in plotting the horizontal axis, but having trouble
bringing all the data together.Not sure yet how to
manipulate them using the data frames:(
Any suggestions and tips will be greatly appreciated.
Thank you
-Kiran
