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=1))) expr # b) - whereas this

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 documentatio...

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. Because...

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()

I think this is mostly a matter of taste, but I liked your version using eval() & substitute() a bit more. For me, do.call() is a heavy hammer I only like to use when needed.. Or wou...

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,

How to assign NULL value to pairlist element while keeping it a pairlist?
Thanks, this was what I expected. There is a desire to eliminate the usage of pairlist from user code, which suggests the alternative of allowing for function arguments to be stored in lists. That's a much deeper change though. On Wed, Oct 12, 2016 at 12:31 PM, Henrik Bengtsson <henrik.bengtsson at gmail.com> wrote: > Michael, thanks for this info. > > I've stumbled upon

error in parallel:::sendMaster
Hi, I am facing a very weird problem with parallel::mclapply. I have a script which does some data wrangling on an input dataset in parallel and then writes the results to disk. I have been using this script daily for more than one year always on an EC2 instance launched from the same AMI (no updates installed after launch) and processed thousands of different input data sets successfully. I now
