I want to use persp to graph my data and it keeps giving me the error increasing 'x' and 'y' values expected, even though my data is in increasing order with respect to x and y.
Here is the code I'm currently using: bob= scan ("SBA3dataTaxonB.txt",what="char") labels = bob[1:3] bob=bob[-c(1,2,3)] bob=as.numeric(bob) bob=array(bob,dim=c(3, length(bob)/3)) bob=t(bob) data.frame(bob) -> bob bob = bob[order(bob[,1], bob[,3]),] persp(bob[,1], bob[,3], bob[,2], log="bob[,1]") The first few lines of the txt file SBA3dataTaxonB.txt look like this: variable TaxonB central 10 19 0.002 10 25 0.002 10 26 0.002 1 17 0.002 1 23 0.002 1 16 0.002 0.1 48 0.002 0.1 47 0.002 0.1 57 0.002 10 15 0.004 10 22 0.004 10 22 0.004 1 21 0.004 1 22 0.004 1 27 0.004 0.1 73 0.004 0.1 62 0.004 Can anyone help me figure out why I am getting this error? And also a possible solution would be greatly appreciated. -Thanks, Amanda -- View this message in context: http://r.789695.n4.nabble.com/error-with-persp-increasing-x-and-y-values-expected-tp4404834p4404834.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.
