I can't seem to determine how to get the name of a list member to substitute as a variable name:
ll <- list("a1" = "a","a2" = "b") t1[t==ll[1], "v"] <- 99 why doesn't this substitute to: t1[t=="a", "v"] <- 99 Thank you! -- Charles Stangor Professor -- Charles Stangor Professor [[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.
