replace an expression with its value, or read macros
...t to evaluate it and make its value a variable with its own value.
}
}
If this were Lisp I'd use backquotes (or "backticks", as some say) and commas—examples of read macros—to do this, but I can't find anything analogous for R. How might I accomplish this in R?

conditional value assignment
...m to get either incantation to perform the assignment. What would be a good way to do this?
Example data:
"TargetColor.1.18." "CannonOriB.1.18." "CannonOriR.1.18."
"B" 5 3
"R" 5 3
Example assignment of tco

list to data frame
...lesList[[22]], ineffFilesList[[23]], ineffFilesList[[24]], ineffFilesList[[25]], ineffFilesList[[26]], ineffFilesList[[27]])
What's an efficient way of doing this such that the computer will do the work of recurring through the list of elements of ineffFilesList?
Much appreciation,

return one vector that is the sum of a list of vectors
.... It seems like I should be able to map the primitive "+" operator onto a list or vector that contains the variable names. If that's a good way to go, what would that look like? Or if that's not a good way to go, would someone please point me in a good direction?
Sincerely,

tests for measures of influence in regression
...e influential by any of the measures. Looks
good! But how does it discriminate between the influential and non-
influential observations by each of the measures? Like does it do a
Bonferroni-corrected t on the residuals identified by the influence
measures or some other test?
Cheers,

transposing data
...Instead what I want is Subject plus up to 1,008 variables encoding RT
at every combination of CannonAngle, CannonOriB, CannonOriR,
nRedPelelts, TargetColor, and tbearing that occurred. Is that
something the reshape function can give me or should I be looking
elsewhere?
