Dear group, apologies for asking a simple question. I have a file where the data looks like this: Probe Intensity 0:0 501.0 1:0 17760.5 2:0 511.0 3:0 18468.3 4:0 199.8 5:0 508.0 6:0 17241.8 7:0 507.5 8:0 17910.0 9:0 482.5 10:0 17480.3 11:0 434.0 12:0 17631.3 13:0 444.8 14:0 17423.0 15:0 505.3 16:0 16693.0 17:0 438.5 18:0 16920.0 19:0 491.3 20:0 16878.0 21:0 486.3 22:0 16582.0 23:0 483.8 24:0 16694.8 25:0 452.3 26:0 16221.5 27:0 438.3 28:0 17119.8 29:0 455.5 30:0 16579.0 31:0 424.5 32:0 16691.3 33:0 472.0
My question is how do I know the distribution of the intensities. My aim is to find out the number of intensities or probes that fall in a certain range. For example 500 probes has intensities ranging from 50 to 150. 300 probes has intensities ranging from 151-250 I have no clue how to do it for 500,000 probes. Can any one please help doing it in R. thanks and apologies again srini ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
