search for: expession

...s of the list, stored as an vector of names: nn <- c("A", "B", "C"), so that I could get list elements like a$nn[1], a$nn[2], etc. Obviously it doesn't work. Instead I do: nn.Exp <- substitute(expression(a$b), list(b=nn[1])) eval(nn.Exp) in a result I get expession(a$"A") but not the value stored in the list. Meanwhile if I manually construct expression as expression(a$"A") and then evaluate it, it works fine. How do I solve that problem? Perhaps using such a list with "stringified" names are not very good programming style, but...

...gh orders anyhow. The issue is that I pass a vector of strings to the function and want to use it as: update(.~.+ do.something.to.the.string(vector.argument.of.strings[i]) or in the code below update(.~.+unknown(facvec[i])) I've tried a whole bunch of things I don't understand parse(),as.expession() and the as.name() below but none seem to work. Here is the function I am using: function(facvec,base.lm){ if ( missing(facvec) || missing(base.lm) ){ cat("This script assesses the contribution of terms in a lm model.\n") cat(" It expects a vector of names and a lm.object...
