...ion halted My package depends on ape, but not Matrix. Matrix is installed, though, on my workstation, as are the other ape dependencies. The check works fine by default and with the --timings option. What is different about --as-cran that makes it unable to find Matrix?

Hello list members I have a problem with modifying a data.frame. As an example given is a data.frame called ex : ex<-data.frame(id=c(1,2,3,4,5,6),obs=c(14,9,20,36,55,47),eff=c("A","A","B","C","C","C")) After that I would like to modify the object ex with the following short script: for (i in ex) { if(ex[i,3]=="A"||

I want to take the first row of each unique ID value from a data frame. For instance > ddTable <- data.frame(Id=c(1,1,2,2),name=c("Paul","Joe","Bob","Larry")) I want a dataset that is Id Name 1 Paul 2 Bob > unique(ddTable) Will give me all 4 rows, and > unique(ddTable$Id) Will give me c(1,2), but not accompanied by the name column.
