search for: collapse

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"...

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 r...

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.or...

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, 550) ) vapply(snp_groups, colla...

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' operation. The 'recycl...

Yes I'd expect that too. But the **collapse** operation in paste() has never been about collapsing **multiple** character vectors together. What it do...

...f 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 collapse should return a character vector of length one. Rather I'm pointing out that it could (perhaps should, imo) simply be an error, which is also consistent, in the strict sense, with previous behavior in that it is the developer simply declining to extend the recycle0 argument to the full paramet...

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[: addressdata].toggleClassName(''collapsed'') } %> </legend> ... some forms etc. here ... </fieldset> In CSS, I do a display:none for the class ''.col...

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 fredhutc...

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. > pas...
