How to obtain multiple lines in a single density plot, with a corrected scale?
- by user1677055
I have recently started working with microarray datasets and am trying to get my hands on R. I wish to make some plots out of my result data, but however I am stuck at the following.
I have the following data (myData),
cpg samp1 samp2 samp3
cpg1 0.43 0.32 0.21
cpg2 0.43 0.22 1.00
cpg3 0.11 0.99 0.78
cpg4 0.65 0.32 0.12
cpg5 0.11 0.43 0.89
And I wish to obtain a density plot for this,
I did the following,
plot (density(MyData$samp1), col="red")
lines (density(MyData$samp2), col="green")
lines (density(MyData$samp3), col="blue")
But doing this does not give me correct plots, because not all sample curves fit within the plot limits. I did try looking for answers, but honestly i am still not able to work this out.
Can you help me know how do i set my scale for the above? Or what additional should I do to the above code, so that all the curves are in range?? I have got many samples, so i need a something that could also automatically assign a different colour curve for each of my sample, after scaling it right.
Thanks in advance..
