I have a table in the following format which provides some information (counts of mapped reads) about exons in some genes across some samples.
Exon Gene sampleA sampleB sampleC E1 A 43 52 12 E2 A 0 24 34 E3 A 19 48 32 E4 A 76 0 23 E5 A 5 87 12 E1 B 12 109 98 E2 B 32 76 11 E1 C 12 0 5 E2 C 4 8 76 E3 C 0 0 32
That is, information about every exon of every gene. I wish to generate a per sample plot (therefore, 3 plots) of counts of all exons in all 3 genes. Within each sample plot, my X-axis would be the exon number and the Y-axis would be the count. And so, I would have 3 "data series" lines (since there are 3 genes) within each plot.
I am new to R and I have no clue how to go about it.
I am wondering if I have to "factor" the gene column in any way to get the exons specific for that gene.?
Any suggestions would be much appreciated.
