Thank you. I really appreciate the help. May i ask two questions.
In the example below: table <- structure(c(4, 7, 0.2, 3, .1, 7, 222, 3, 10, 5, 11, 8, 8, 10, 7), .Dim = c(5L, 3L), .Dimnames = list(c("gene1", "gene2", "gene3", "gene4", "gene5"), c("codon1", "codon2", "codon3"))) Library(ca) plot(ca(table, suprow=c(4, 5))) i get an output plot like this: http://r.789695.n4.nabble.com/file/n4456264/Screen_shot_2012-03-08_at_12.16.41.png is it possible to add in code somewhere so that the nodes of interest are not open circles, but are encompassed by a shading on them, similar to this: http://r.789695.n4.nabble.com/file/n4456264/Screen_shot_2012-03-08_at_12.18.34.png And my second question, in this line of the code here: plot(ca(table, suprow=c(4, 5))) is it possible to edit "suprow=c(4, 5)" to say "suprow=c(the genes that are in a certain file)", i.e rather than manually type each gene in, get the code to read in a file? When i try move "gene 4" and "gene 5" to a seperate file, and try to read it in, i get: > plot <- ca(table,suprow=c(file)) Error in sort.int(x, na.last = na.last, decreasing = decreasing, ...) : 'x' must be atomic Many thanks for your time. -- View this message in context: http://r.789695.n4.nabble.com/find-points-on-a-graph-tp4452746p4456264.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.
