Calling substitute(expr, list(a=1)) when expr <- expression(a+b+c)
# The result I am after is the result after a substitution in an expression, such as substitute(expression(a+b+c), list(a=1)) expression(1 + b + c) # However, the way I want to do it is for a an expression "stored as a variable" as (expr <- expression(a+b+c)) expression(a + b + c) # a) The following does not work (expr2 <- substitute(expr, list(a...

stopifnot
A private reply by Martin made me realize that I was wrong about stopifnot(exprs=TRUE) . It actually works fine. I apologize. What I tried and was failed was stopifnot(exprs=T) . Error in exprs[[1]] : object of type 'symbol' is not subsettable The shortcut assert <- function(exprs) stopifnot(exprs = exprs) mentioned in "Warning" section of the documentati...

stopifnot
Another possible shortcut definition: assert <- function(exprs) do.call("stopifnot", list(exprs = substitute(exprs), local = parent.frame())) After thinking again, I propose to use ??? ? ? stop(simpleError(msg, call = if(p <- sys.parent()) sys.call(p))) - It seems that the call is the call of the frame where stopifnot(...) is evaluated.

How to test if an object/argument is "parse tree" - without evaluating it?
This may have been asked before, but is there an elegant way to check whether an variable/argument passed to a function is a "parse tree" for an (unevaluated) expression or not, *without* evaluating it if not? Currently, I do various rather ad hoc eval()+substitute() tricks for this that most likely only work under certain circumstances. Ideally, I'm looking for a isParseTree() function such that I can call: expr0 <- foo({ x <- 1 }) expr1 <- fo...

How to assign NULL value to pairlist element while keeping it a pairlist?
...ment lists (which are > pairlists, but the user does not need to know really). > Or did you imply, Henrik, that would you want is not achievable > with these? Martin, thanks for bringing these options up. Just to make sure no one misreads these comments - I'm not operating on as.list(expr) - it was just used to show the content of the expression. In my case, I'm operating / modifying expressions and not functions per se, e.g. expr <- quote(function(x = 1) x) It's not clear to me how I would go about to modify this to be the equivalent of: expr <- quote(functi...

matching last argument in function
I often want to temporarily modify the options() options, e.g. a <- seq(10000001, 10000001 + 10) # some wide object with.options <- function(..., expr) { options0 <- options(...) tryCatch(expr, finally=options(options0)) } Then I can use: with.options(width=160, expr = print(a)) But I'd like to avoid explicitly naming the expr argument, as in: with.options(width=160, print(a)) How can I do this with R's argument matching?

function curve() (PR#14191)
Full_Name: Georgi Boshnakov Version: 2.10.1pat OS: Windows XP Submission from: (NULL) (130.88.123.205) When calling programmatically function curve() from package:graphics I experienced some trouble since it reports stop("'expr' must be a function or an expression containing 'x'") even if expr is "expression". Naturally, the user message uses "expression" in its usual generic meaning but it is somewhat confusing that an object of type "expression" is rejected. The message i...
