Without 'collapse', 'paste' pastes (concatenates) its arguments elementwise (separated by 'sep', " " by default). New in R devel and R patched, specifying recycle0 = FALSE makes mixing zero-length and nonzero-length arguments results in length zero. The result of paste(n, "th", sep = "", recycle0 = FALSE) always have the same length as

There is still the situation where **both** 'sep' and 'collapse' are specified: > paste(integer(0), "nth", sep="", collapse=",") [1] "nth" In that case 'recycle0' should **not** be ignored i.e. paste(integer(0), "nth", sep="", collapse=",", recycle0=TRUE) should return the empty string

i have a data frame(dat) which has many variables.and i use the following script to get the crosstable. >danx2<-c("x1.1","x1.2","x1.3","x1.4","x1.5","x2","x4","x5","x6","x7","x8.1","x8.2","x8.3","x8.4","x11",

I agree with Herve, processing collapse happens last so collapse=non-NULL always leads to a single character string being returned, the same as paste(collapse=""). See the altPaste function I posted yesterday. Bill Dunlap TIBCO Software wdunlap tibco.com On Fri, May 22, 2020 at 9:12 AM Herv? Pag?s <hpages at fredhutch.org> wrote: > I think that > >

Totally agree with that. H.

Gabe, It's the current behavior of paste() that is a major source of bugs: ## Add "rs" prefix to SNP ids and collapse them in a ## comma-separated string. collapse_snp_ids <- function(snp_ids) paste("rs", snp_ids, sep="", collapse=",") snp_groups <- list( group1=c(55, 22, 200), group2=integer(0), group3=c(99,

I think that paste(c("a", "b"), NULL, c("c", "d"), sep = " ", collapse = ",", recycle0=TRUE) should just return an empty string and don't see why it needs to emit a warning or raise an error. To me it does exactly what the user is asking for, which is to change how the 3 arguments are recycled **before** the 'sep'

Yes I'd expect that too. But the **collapse** operation in paste() has never been about collapsing **multiple** character vectors together. What it does is collapse the **single** character vector that comes out of the 'sep' operation. So paste(x, y, z, sep="", collapse=",") is analogous to sum(x + y + z) The element-wise addition is analog to the 'se...

I understand that this is consistent but it also strikes me as an enormous 'gotcha' of a magnitude that 'we' are trying to avoid/smooth over at this point in user-facing R space. For the record I'm not suggesting it should return something other than "", and in particular I'm not arguing that any call to paste *that does not return an error* with non-NULL

Hi all, I use txtProgressBar to monitor progress of large computations. What I miss is the ability to redirect the progress bar to a stream other than stdout, specifically to the message stream. This would be useful for running Sweave scripts: When redirected to stderr, the bar could be visible even though console output is diverted to the output file (and there would be no cluttering of the

Hey there, (First steps in Ruby and Rails...) I''m trying to make a fieldset collapsible, like they are, for example, on many Drupal pages. What I''ve figuared out is the following: <fieldset id="addressdata" class="collapsible collapsed"> <legend> <%= link_to_function("Show/Hide Addressdata") { |page| page[:

Apparently there is one or more concepts that I do not fully understand from the descriptions of a function and the apply material. I have been reading the mail from this forum and have learned much but, in this case, what I have been reading here and from the manual isn't enough. The following code produces what I want with the for loop. From what I have read from this forum, a for

Hi all, This makes sense to me, but I would think that recycle0 and collapse should actually be incompatible and paste should throw an error if recycle0 were TRUE and collapse were declared in the same call. I don't think the value of recycle0 should be silently ignored if it is actively specified. ~G On Fri, May 15, 2020 at 11:05 AM Herv? Pag?s <hpages at fredhutch.org> wrote: >

I agree: paste(collapse="something", ...) should always return a single character string, regardless of the value of recycle0. This would be similar to when there are no non-NULL arguments to paste; collapse="." gives a single empty string and collapse=NULL gives a zero long character vector. > paste() character(0) > paste(collapse=", ") [1] "" Bill
