Hi, I seem to not be able to assign NULL to an element of a pairlist without causing it to be coerced to a plain list. For example:
> x <- pairlist(1, 2) > class(x) [1] "pairlist" > x[1] <- list(NULL) > class(x) [1] "list" This actually true for all [()<- assignments regardless of list value, e.g. > x <- pairlist(1, 2) > x[1] <- list(0) [1] "list" I also tried assigning a pairlist(), but still the same problem: > x <- pairlist(1, 2) > x[1] <- pairlist(0) [1] "list" The only workaround I'm aware of is to: x <- as.pairlist(x) at the end. Any other suggestions? Thanks, Henrik ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
