cbind(deparse.level=2,...) problems
Should the deparse.level=2 argument to cbind and rbind be abandoned? It is minimally documented, not used in any CRAN package, and causes some problems. E.g., (a) If a matrix input has row names but not column names cbind(deparse.level=2,...) stops. > m<-matrix(11:14,nrow=2,ncol=2,dimnames=list(Row=c("R1","R2"),Col=charact er())) > cbind(m, 101:102,

Mitigating Stalls Caused by Call Deparse on Error
...r "do.call(paste0, list(abs, x))" ??? ##? $ : chr "system.time(do.call(paste0, list(abs, x)))" The first time I noticed this I thought my session had frozen/crashed as the standard interrupt ^C does not work during the deparse.? The stall happens when on error the call stack is deparsed prior to being saved to `.Traceback`.? The deparsing is done by `deparse1m` in native code, with the value of `getOption('deparse.max.lines')` which defaults to all lines. Since there is little value to seeing millions of lines of deparsed objects in `traceback()`, a simple work-around is...

[External] Mitigating Stalls Caused by Call Deparse on Error
...our entire R session externally. It seems a shame to allow a big usability issue for `do.call` to remain when there is a simple solution at hand, especially since the complete deparse of large objects likely serves no purpose in this case. Obviously, if storing the actual calls instead of their deparsed equivalents in .Traceback causes problems I'm not anticipating, then that's different.? Is that the case? Best, Brodie.

deparse - width.cutoff
I have a question about "deparse" function in R What is the reason that "deparse" use an argument like "width.cutoff" ? Why the maximum cutoff is 500? I was manipulating an R formula and used "deparse". Since the length of user's formula was greater then 500, my code didnt work. thanks Johan johan Faux <johanfaux@yahoo.com> wrote: I have a

Parsing and deparsing of escaped unicode characters
In both R and JSON (and many other languages), unicode characters can be escaped using a backslash followed by a lowercase "u" and a 4 digit hex code. However when deparsing a character vector in R on Windows, the non-latin characters get escaped as "<U+" followed by their 4 digit hex code and ">": > x <- "I like \u5BFF\u53F8" > cat(x) I like

deparse with parentheses for SUBSET
Hi, maybe there?s a reason for it, but the discrepancy between the handling of `[` and `$` in deparsing seems odd to me: > substitute(a[1], list(a = quote(x * y))) x * y[1] > substitute(a$b, list(a = quote(x * y))) (x * y)$b The former is still executed in the right order (`*` first, then `[`), which is not what you?d expect looking at the deparse result. Some code that shows the execution

question about deparse(substitute(...))
Dear R helpers: I like to apply deparse(substitute()) on multiple arguments to collect the names of the arguments into a character vector. I used function test.fun as below. it works when there is only one input argument. but it does not work for multiple arguements. can someone kindly help? test.fun <- function(...){deparse(substitute(...))} test.fun(x) #this works test.fun(x,y,z) # I like

nlme: bug in getCovariateFormula (PR#1038)
I found that predict.gnls failed with a wierd error message about a non-numeric argument to a binary vector in one of three nearly identical uses. Error in Inh/Ki : non-numeric argument to binary operator (Inh and Ki are arguments to the function used in the formula for the object whose predictions were requested). It turns out that the problem is in getCovariateFormula(). The final line in

deparse(substitute(foo))
I see that plot.default uses deparse(substitute(x)) to extract the character name of an argument and put it on the vertical axis. Hence: foo <- 1:10 plot( foo ) will put the label "foo" on the vertical axis. However, for a function that takes a "..." list as an input, I can only extract the first argument name: x <- 1:10 y <- 10:20 foo <- function(...) {

deparse operators in expressions
Hi, I observed a slight problem in deparse(): it will add spaces around most operators except /. I wonder if this is easy to fix. I know this is quite trivial, but I will appreciate if / is not treated as an exception. Examples: > deparse(expression(1/1)) [1] "expression(1/1)" > deparse(expression(1+1)) [1] "expression(1 + 1)" > deparse(expression(1%in%1)) [1]

why does do_stop call R_GetTraceback ?
I'm using: R 2.15.1 (beta), 2012-06-11, svn.rev 59557, x86_64-unknown-linux-gnu And I normally use: options("error"=recover) I recently ran into a problem where when my code called stop(), recover() was incredibly slow (hours) because it was trying to deparse an extremely large call. I worked around that by instead using my own recover function which avoids deparsing anything

Issue when calling deparse(substitute(x)) from C with "anonymous" R vectors ?
Dear list, When calling R from C, what appears like a spurious error can be triggered during the execution of chisq.test(x, y). This is happening when the following conditions are met: - x and y are "anonymous" C-level R vectors (they do not have a symbol), but they are protected from garbage collection - x and y are "not too small" (it was experienced as soon as they are

Too many spaces in deparsed complex numbers with digits17 control option
If you set the "digits17" control option in deparse, you get a lot of unnecessary space in the representation of complex numbers. > deparse(0 + 0i) [1] "0+0i" > deparse(0 + 0i, control = "digits17") [1] "0 + 0i" As far as I can tell, the logic for this comes from this piece of /src/main/deparse.c: if (TYPEOF(vector) == CPLXSXP

deparse() and the 'else' statement
Hi all, It is recommended in ?'if' that we use 'else' right after '}' instead of starting a new line, but I noticed deparse() will separate '}' and 'else' when the 'if...else' clause is used inside {...} (e.g. function body). Here is an example: ## if/else inside {} > cat(deparse(parse(text='function(){if (TRUE) {1} else {2}}')),
