Hi everyone, I'm using the following code to go over every element of a data frame (row wise). The problem I am facing is that the outer 'x' variable is not incrementing itself, thus, only one row of values is obtained, and the program does not proceed to the next row.
This is the code: while(x<=coln) { while(y<=rown) { n<-as.numeric(df[[y]][x]); if(n>0) { lim<-(n-1); S<-100; (...) } opdf[[y]][x]<-sum; } y<-y+1; } x<-x+1; } Here is a sample of the input data: GENE A CD EF GH IK LM NP QR ST VW Y 2amt:Amet_0001 29 023 3417 1612 4229 39635 20 1325 3427 323 12 3amt:Amet_0002 19 315 4212 188 3525 437 2613 914 2120 30 0 8 [[alternative HTML version deleted]] ______________________________________________ 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.
