Yes, I agree it looks like a bug, and it's still there in R-devel. The problem is that the assignment sets the R_Visible flag to false, and the indexing never sets it to true. The same problem happens with a[t <- 'b'], whether a is a list or not: > a <- c(b=5, c=6, d=7) > a[t <- 'b'] > .Last.value b 5 Duncan Murdoch ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
