Hi all, I have read posts of heat map creation but I am one step prior -- Here is what I am trying to do and wonder if you have any tips? We are trying to map sequence reads from tumors to viral genomes.
Example input file : 111 abc 111 sdf 111 xyz 1079 abc 1079 xyz 1079 xyz 5576 abc 5576 sdf 5576 sdf How may xyz's are there for 1079 and 111? How many abc's, etc? How many times did reads from sample (1079) align to virus xyz. In some cases there are thousands per virus in a give sample, sometimes one. The original file (two columns by tens of thousands of rows; 20 MB) is text file (tab delimited). Output file: abc sdf xyz 111 1 1 1 1079 1 0 2 5576 1 2 0 Or, other ways to generate this data so I can then use it for heat map creation? Thanks for any help you may have, rtsweeney palo alto, ca -- View this message in context: http://r.789695.n4.nabble.com/frequency-count-rows-data-for-heat-map-tp2338363p2338363.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
