Hello. First, I'm thankful about your wonderful project.
However, I have serious worries about the reliability of R. I found the next bug which I consider important because in my job everytime We work with datanames like next. Please see below: b=data.frame(matrix(1:9,ncol=3)) names(b)=c("q99","r88","s77") >b q99 r88 s77 1 1 4 7 2 2 5 8 3 3 6 9 > b$q9 [1] 1 2 3 Please note that the variable q9 does not exist in the dataframe, but you can see that R show q9 (as q99).
